Why Is Water So Important? Here’s What You Need to Know

How water works in your body, how much water do you need, how to stay hydrated.

Water is a major component of your body, accounting for 50–60% of your total weight. It is vital for many important body functions, from flushing out waste to lubricating your joints.

Your body constantly loses water throughout the day through urinating, sweating, and breathing. You should consume enough water from foods and beverages daily to prevent dehydration .

This article covers research-backed reasons why your body needs water and how much you need each day.

All body cells, organs, and tissues require water to function. Generally, a person can only survive without water for a few days.  

It Maintains a Normal Body Temperature

Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat).

When the body becomes too hot, it loses water through sweat . The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.

If a person becomes dehydrated, they can't produce enough sweat to cool their body. This can cause the body's temperature to reach dangerous levels, leading to heat stroke .

Avoid dehydration by drinking plenty of water if you're working outside or sweating more than usual.

It Protects Your Joints, Spinal Cord, and Other Tissues

Water acts as a lubricant in the mouth (through saliva ) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid , which lubricates, cushions, and protects the joints.

Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It Transports Nutrients and Gets Rid of Waste

As a major component of blood, water helps transport nutrients and oxygen to cells throughout the body. Water also helps carry waste from the body for excretion through perspiration, urination, and bowel movements.

The kidneys need water to effectively filter waste from the blood and flush it from the body as urine. Staying adequately hydrated helps prevent kidney stones and urinary tract infections (UTIs) , which can harm the kidneys.

Prevents Dehydration

Drinking water daily can help prevent dehydration, a condition that occurs when you lose more fluids than you absorb.

Early signs of dehydration include:

  • Feeling thirsty
  • Dark-colored urine
  • Urinating less than usual

Because water is involved in so many body functions, dehydration can eventually cause life-threatening symptoms, including:

  • Rapid breathing
  • Rapid heartbeat
  • Inability to urinate

People who exercise in the heat, work outdoors, or have certain health conditions that cause them to urinate or sweat more than usual are at a greater risk of dehydration.

It Aids Digestion

Your saliva is primarily made up of water. Saliva is a digestive juice that moistens food, allowing it to move easily through the esophagus into your stomach. Saliva also contains enzymes that help break down starches in food.

As the digestive process continues, water helps break down food, allowing your body to absorb nutrients. Water also makes bowel movements easier.

It Protects Against Chronic Illness and Boosts Longevity

Adequate hydration is linked to healthy aging and longevity. One potential reason for this is that decreased water intake can lead to higher sodium concentrations in the blood, which raises the risk of chronic disease.

Studies suggest that adults who stay hydrated are healthier and less likely to develop chronic diseases, including heart and lung disease . Well-hydrated adults also seem to live longer than adults who don't consume enough fluids.

It Improves Mood and Cognitive Function

Dehydration may cause fatigue and confusion and may be linked to symptoms of anger and depression. In a small study, it was linked to poor cognitive function, potentially affecting attention span and working memory.

One study of young adults looked at the effects of water on cognitive performance and mood after 12 hours of water restriction. Researchers found that 200 milliliters of water improved thirst, anger, fatigue, and overall mood. However, 500 milliliters was optimal, improving mood and cognitive performance.

The amount of water you need depends on several factors, including age, sex, activity level, and health status.

For healthy individuals, the adequate daily water intake is around 11.5 cups for women and about 15.5 cups for men. This includes fluids consumed from all foods and beverages.

Experts estimate that most people get around 20% of their daily water intake from food. This means women should drink about 9 cups of fluid daily, while men should aim for 13 cups to maintain adequate hydration.

People who live in warmer climates, are more physically active, or are experiencing an illness that causes fever and/or diarrhea or vomiting have increased fluid needs.

One easy way to see if you are properly hydrated is to check the color of your urine. If you are drinking enough water, your urine will be pale yellow. If it is dark, you may need to increase your consumption.

Individuals with heart failure or kidney disease may need to limit their fluid intake.

Can You Drink Too Much Water?

Drinking too much water can lead to water intoxication or overhydration, which occurs when the kidneys cannot flush out excess water. This can cause a medical emergency due to decreased sodium concentrations in the blood ( hyponatremia ). To avoid water intoxication, do not drink more than 48 ounces, or six cups, per hour.

If you find it challenging to stay hydrated, here are some helpful tips to keep in mind:

  • Keep a reusable water bottle with you and refill it throughout the day
  • Choose water or sparkling water instead of sugary beverages
  • When you feel thirsty, drink water
  • Change things up by squeezing fresh lemon or lime into your water or adding a few berries or cucumber slices
  • Snack on water-rich fruits and vegetables , including watermelon, cantaloupe, lettuce, and celery, throughout the day
  • Keep track of your water intake by using a water tracker app
  • Drink water with all meals

Water is vital for your health. It is necessary for temperature regulation, digestion, nutrient absorption, and body waste removal. Drinking water daily can prevent dehydration, a condition that can cause mood and memory problems, constipation, and kidney stones.

People who work in high temperatures, exercise at high intensities, or are sick are at a greater risk of dehydration. Talk to a healthcare provider or registered dietitian to determine the right amount of water for you.

Have you noticed that everything alive needs water? Your pets, trees, and your family, too. So why do you think that is? It’s true that our bodies and other living things are made from all sorts of different things but water makes up a lot of it. Also, when you look at a globe of Earth, there really is a lot of water! Scientists have found that all living things need water. So, if we would like to try to find living things from some other planet, then maybe we should look for places that also have water.

Disciplinary Core Ideas

LS1.C: Organization for Matter and Energy Flow in Organisms: All animals need food in order to live and grow. They obtain their food from plants or from other animals. Plants need water and light to live and grow. (K-LS1-1)

ESS3.A: Natural Resources: Living things need water, air, and resources from the land, and they live in places that have the things they need. Humans use natural resources for everything they do. (K-ESS3-1)

LS2.A: Interdependent Relationships in Ecosystems: Plants depend on water and light to grow. (2-LS2-1)

ESS2.B: Plate Tectonics and Large-Scale System Interactions: Maps show where things are located. One can map the shapes and kinds of land and water in any area. (2-ESS2-2)

Big Ideas: Water is critical for life. Living things are made up of water. When looking for life beyond Earth, places that have water are of great interest.

Boundaries: Students in this grade band describe patterns of what plants and animals (including humans) need to survive. Examples of patterns could include that animals need to take in food but plants do not; the different kinds of food needed by different types of animals; the requirement of plants to have light; and that all living things need water. (K-LS1-1)

K-8 Water in the Biosphere. In this one-hour lesson, students make their own qualitative observations outdoors. Then they examine the life they saw and how water in the biosphere is part of the greater water cycle on Earth. This lesson can stand alone or be a part of a larger unit which includes the water cycle, Earth’s water and interacting spheres. NASA . https://pmm.nasa.gov/education/lesson-plans/water-biosphere

K-8 The Water Cycle. In this one-hour lesson, students participate in a web quest to learn about the water cycle, and then build a mini-model of the water cycle to observe how water moves through Earth’s four systems.

Grades 3-5 or Adult Emerging Learner

All living things on Earth need water. Everything from people, plants, animals, and even mushrooms and things too small to see need water to survive. Even things like cacti in a desert need some water to live. Water seems to be very important for life. Have you ever looked at a globe – there is a lot of water! Since all living things that we know of need water and many of us want to know if there could be other living things out there beyond Earth, then one thing we can do is investigate places with water beyond Earth. Mars had rivers and lakes of water a long time ago and there could still be some water deep underground there today. Also, there are some moons around other planets that have lots of water. We need to continue to investigate these places and more because if there is water, then there might be life, too.

ESS2.A: Earth Materials and Systems: Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity break rocks, soils, and sediments into smaller particles and move them around. (4-ESS2-1) *Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather. (5-ESS2-1)

ESS2.B: Plate Tectonics and Large-Scale System Interactions: The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near their edges. Maps can help locate the different land and water features areas of Earth. (4-ESS2-2)

PS3.D: Energy in Chemical Processes and Everyday Life: The energy released [from] food was once energy from the Sun that was captured by plants in the chemical process that forms plant matter (from air and water). (5-PS3-1)

LS1.C: Organization for Matter and Energy Flow in Organisms: Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion. (5-PS3-1) *Plants acquire their material for growth chiefly from air and water. (5-LS1-1)

LS2.A: Interdependent Relationships in Ecosystems: The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants.

LS2.B: Cycles of Matter and Energy Transfer in Ecosystems: Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. (5-LS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Nearly all of Earth’s available water is in the ocean. Most freshwater is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere. (5-ESS2-2)

Systems and System Models: A system can be described in terms of its components and their interactions. (5-ESS2-1, 5-ESS3-1)

Big Ideas: All living things on Earth need water. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. In the past, Mars had an abundance of water and it still has water today as do some of the moons around other planets in our solar system. These may be the best places to find life outside of Earth.

Boundaries: Students in this grade band are learning to graphically represent the distribution of water on Earth, including its oceans, lakes, glaciers, ground water, and polar ice caps. (5-ESS2-2)

One attribute that is common to all living things that we know of is the need for water to survive. Even organisms that live in very dry places need water to live. Why? Why is water so important to living things? One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get energy in and to move waste out.

Water is made up of two atoms of hydrogen and one atom of oxygen that make a molecule. But water is a certain type of molecule called a “polar molecule”. Polar molecules have one side of the molecule that’s a bit more positively charged and the other side a little more negatively charged. This allows water to more easily break apart or dissolve other molecules. That’s why you can dissolve salt in water! There are actually a lot of other liquids that can do this but water has other advantages as well. Water is very plentiful. About 70% of the surface of Earth is covered by water, from our oceans and our lakes to our rivers and streams. It turns out that water is also plentiful in the solar system. Comets have a lot of water within them, there is ample evidence that liquid water existed on ancient Mars in great quantities, and many moons have water under their surfaces.

Water is super important for life as we know it! There might be other forms of life out there that don’t rely on water the way we do, but looking for alien life in places with lots of water is one good way to start searching for possible extraterrestrial life.

LS1.C: Organization for Matter and Energy Flow in Organisms: Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (MS-LS1-6)

PS3.A: Definitions of Energy: The term “heat” as used in everyday language refers both to thermal energy (the motion of atoms or molecules within a substance) and the transfer of that thermal energy from one object to another. In science, heat is used only for this second meaning; it refers to the energy transferred due to the temperature difference between two objects. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

PS3.D: Energy in Chemical Processes and Everyday Life: The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen.

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water’s movements — both on the land and underground — cause weathering and erosion, which change the land’s surface features and create underground formations. (MS-ESS2-2)

ESS3.A: Natural Resources: Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. (MS-ESS3-1)

Structure and Function: Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function. (MS-LS1-2)

Big Ideas: All living things on Earth need water. It is critical to cellular function. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. As a polar molecule, it has specific chemical properties, like the ability to dissolve other molecules. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, astrobiologists look for water on other worlds as an indicator of possible life.

Boundaries: Students in this grade band construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes. Emphasis is on how these resources are limited and typically non-renewable. (MS-ESS3-1)

An outstanding curiosity is that in the polar regions, some craters appear to have ‘anomalous reflectivity’ in the shadowed areas of these craters. One interpretation is that this is caused by subsurface ice. The MESSENGER spacecraft hopes to explore this issue in the next few years. In this activity, students measure the surface areas of these potential ice deposits and calculate the volume of water that they imply.

Grades 9-12 or Adult Sophisticated Learner

All life on this planet needs water to survive. Some life can live with very little water in extremely dry places but they still need water. As we strive to find life beyond Earth, it is important to consider what life on Earth tells us about where to look. Why is water so important for life? Water supports cell functions. All organisms are made of cells, from microbes to the largest animals. All of life’s functions are completed within cells. Life needs chemical reactions to take place in order to gain energy, grow, and get rid of waste. Water is a liquid which allows the chemistry of life to take place. It is also a polar molecule which allows most other molecules to be dissolved. Because of this, we call water a “solvent”. Having such a good solvent as water is critical for the functions of life. But there are also some other reasons why water is so important:

Water is plentiful! Hydrogen is the most plentiful element in the universe and oxygen the most plentiful in Earth’s crust. On Earth, about 70% of the surface is covered by water. But there’s also lots of water in other places in our solar system. For instance, we’ve found many lines of evidence that lots of water existed on the surface of Mars during its early times, and Mars currently has a lot of frozen water under its surface. Comets contain mostly water ice. There are lots of moons in our solar system that are made of a lot of water ice, and there are even some moons with liquid water oceans under their icy crusts (like Europa and Enceladus).

Water still has other advantages as a solvent for life. For instance, water stays in the liquid phase over a large range of temperatures compared to some other solvents. That allows more places to have the potential for liquid water. It also has a high heat capacity. This means that water offers some protection to organisms from quick or drastic temperature changes.

Water also has an interesting property with regard to the density of ice. For many molecules, the solid has a higher density than the liquid. So, for most molecules, the solid would sink in the liquid. But this isn’t the case with water. For water, ice is actually less dense than liquid water. This is why ice floats! If this didn’t happen, then all of the organisms that live in the bottoms of lakes in the winter time would be completely frozen. But, even worse, during times in our planet’s history when the world has become very cold (causing what we call Snowball Earth), if frozen water sank, then all of Earth’s ocean life would have become frozen and maybe died!

If we want to understand how life works, then it’s really important to understand the chemistry of water. And astrobiologists who are wondering if we’re alone in the universe need to be aware of the potential for water to be important for other kinds of life as well. Right now, we’re investigating worlds like Enceladus and Europa, Mars, and other solar system bodies that show signs of water. Also, beyond our solar system, we’re looking for exoplanets that have the potential for liquid water at their surfaces, since they might be important places for us to look for possible extraterrestrial life.

PS3.A: Definitions of Energy: Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. (MS-PS3-1) ▪A system of objects may also contain stored (potential) energy, depending on their relative positions. (MS-PS3-2) Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

PS3.D: Energy in Chemical Processes and Everyday Life: The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (MS-LS1-6)

LS2.C: Ecosystem Dynamics, Functioning, and Resilience: Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health. (MS-LS2-5)

ESS2.A: Earth’s Materials and Systems: All Earth processes are the result of energy flowing and matter cycling within and among the planet’s systems. This energy is derived from the Sun and Earth’s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth’s materials and living organisms. (MS-ESS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land. (MS-ESS2-4) ▪ Global movements of water and its changes in form are propelled by sunlight and gravity. (MS-ESS2-4)

ESS3.A: Natural Resources: Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. These resources are distributed unevenly around the planet as a result of past geologic processes. (MS-ESS3-1)

ESS2.D: Weather and Climate: Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns. (MS-ESS2-6) The ocean exerts a major influence on weather and climate by absorbing energy from the Sun, releasing it over time, and globally redistributing it through ocean currents. (MS-ESS2-6)

Stability and Change: Much of science deals with constructing explanations of how things change and how they remain stable. (HS-ESS2-7)

Big Ideas: All living things need water. Water is critical to cellular function, chemical reactions, and thermal regulation. Water is less dense when a solid and stays in the same state over a wide temperature range. It is abundant on Earth and a common thread between all living things. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, Astrobiologist look for water on the surface and atmosphere of exoplanets as an indicator that the planet could support life. Understanding the chemistry of water is important to understanding how life works.

Boundaries: In this grade band, students investigate the properties of water and its effects on Earth materials and surface processes including chemical investigations like chemical weathering and recrystallization. (HS-ESS2-5)

Storyline Extensions

Water is so cool.

The range of temperatures at which water stays liquid is rather large compared to most other common solvents. For instance, at sea level methane freezes at -182 Celsius © and boils at -162 C (a range of 21 C) and ammonia freezes at -78 C and boils at -34 C (a range of 44 C), meanwhile water freezes at 0 C and boils at 100 C (a range of 100 C). This means that the range of temperatures where water is liquid is more than twice that of ammonia and almost five times more than that of methane.

Water has a high surface tension. This means that that the molecules at the surface of a body of water are attracted to each other and hold each other together. You can see this yourself by filling a glass with water to the very tippy top and then seeing how many more drops of water you can get into it. You’ll be surprised to find that you can actually get a good bit more water into the glass! The high surface tension of water is also why some insects, like water striders, are able to move around on top of water without sinking into it. It also is related to something called “capillary action”, which is used by many plants to draw water up from the ground against gravity.

It’s actually really rare for a solvent to be more dense as a liquid than as a solid. We know of other elements and molecules that are more dense as liquids, but it’s far more common for the solid form of a substance to be more dense.

[note: this is fairly advanced] Oxygen is a member of the group of elements known as the “oxygen family” (also sometimes called the chalcogens). These are the elements in the periodic table that are in group 16 (the vertical column starting with oxygen and going down). They include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). All of these elements can form bonds with two hydrogen atoms. However, none of the other chalcogens come close to oxygen in its large range of temperatures where it is a liquid. This is because oxygen is much more electronegative (much greedier for electrons) and makes a far more polar molecule than the others.

The water was crystal clear, and the colours of the fish and coral were so vibrant and beautiful. After snorkelling, we stopped at a small beachside restaurant for lunch, where we enjoyed fresh seafood and cold drinks while watching the waves roll in. It was a memorable day, and I will always cherish the time I spent in the water on that trip. This trip reminded me that one of my best memories was only possible because water exists. It showed me the life that water holds below land, like coral reefs and also how beautiful animals exist, like turtles.

One of the most important resources we have on the earth is this all-purpose solvent. Water is essential to life, and we cannot exist without it. After all, it covers about 70% of the planet.

Essay on Save Water Save Life

Water is the most important and valuable natural resource on Earth. It sustains all life. There is no life without water. Water is not only important for human beings but for the entire ecosystem. Without enough water, the existence of humans, as well as animals, is next to impossible. After fresh air, water is the second most important natural resource for the survival of any living being. 

Water is necessary for the survival of each living creature on this planet, be it a small worm, plant, or full-grown tree.  Animals and plants  cannot survive without water. About 71% of Earth’s surface is covered with water. Unfortunately, only 3% of the water available  is freshwater. About two-thirds of the freshwater lies in the form of frozen glaciers and ice caps. The rest of the small portion is available in the form of groundwater and surface water. 

We totally depend on water for multiple purposes. Water is used in agriculture for the irrigation of crops. We use water for drinking, cooking, cleaning, bathing, and other domestic purposes. Water is used for recreational activities. In industries, water is used as a coolant, solvent and also used in other manufacturing purposes. Hydroelectricity is generated with the help of water. Water is also used for navigation and transportation of goods. This tells us how water is the most essential component of life and every drop of water is vital for sustenance. Therefore, water conservation is important to save life on this planet.

Importance of Water:

The basic use of water is drinking, bathing, agriculture, irrigation, hospitality, factories, etc.

Water helps in blood circulation and improves metabolism in the human body

The entire aquatic ecosystem is located in water. It is a home for all the aquatic animals

Water is a major source of transportation after land and air.

Water aids in saliva secretion and oxygen delivery to our bodily cells.

 Some countries have abundant water resources for their residents and serve        the people, whereas others lack natural resources even for survival.

Depletion of fresh water has become a threat to our existence. According to some scientists, the quantity and the quality of water are degrading day by day. Although Earth is covered with almost 71% of water, the quality is that we cannot use it in day-to-day life for domestic purposes. Water quality is so poor that people in some places are prone to several water-borne diseases such as Eluru, caused by contaminated water. 

These instances are eye-opening examples and should be taken seriously for better living conditions for us and our future generation.

Below are the Reasons for Shortage of Fresh Water:

Growth of population leads to excessive consumption of water. 

Daily excessive wastage of water.

The rapid growth of industries has increased the problem of proper disposal of waste material from them. The waste products from these industries contain extremely poisonous elements that are polluting the rivers and other water bodies. 

Pesticides and chemical fertilisers that are used to treat crops also pollute the fresh water. 

Sewage waste that is dumped into the rivers is making the water unsuitable for drinking and washing causing several water-borne diseases like cholera, jaundice and typhoid.  

Use of plastics and disposing them carelessly in the water bodies are affecting aquatic life and further disturbing the entire ecosystem.

Global warming is another major reason for the scarcity of water on earth. According to several types of research, because of global warming, the world will face more stress for water scarcity till the year 2050.

 We now need to be aware of the depletion of fresh water and take adequate    measures to stop this. 

Saving Water: Need of the Hour

Many places face extreme water scarcity due to extremely bad weather conditions, leading to less rainfall and groundwater depletion. In other parts of the world, groundwater is either unusable or overused. As the world's population is growing, so increase in industries and globalisation, causing groundwater to be overused and resulting in water scarcity.

The World Health Organisation (WHO) data shows that many people on this planet don't have access to clean and fresh drinking water. These situations are becoming worse day by day, and we need an immediate plan to control this situation. Various collective measures have to be taken by every individual on this planet and the government of every country to control water scarcity.

Government should impose some strict rules for the conservation of water. The government and the citizens have to take the initiative to create awareness and promote the “conservation of water.” One such initiative taken by the Modi government in India was “JANSHAKTI FOR JALSHAKTI.” This programme began as a means of working toward a brighter future.

Initiatives taken by Some State Governments:

The Punjab government contributed to saving water resources by avoiding waterlogging and fixing the drain  leakage.

The Rajasthan government has taken the initiative to construct small ponds, which  helped the local people of Rajasthan in many ways.

Villages of Telangana have constructed water tanks to conserve rainwater for future use.

These states are an inspiration, and others should also take a step forward to conserve and clean the water, water bodies, and groundwater.

Water saving should be and is the universal responsibility of every human being, living on this Earth.

There are many ways in which we can save water and reduce their pollution:

Be responsible to save water daily. Use only the required amount of water and avoid wastage. We should use water wisely.

We should use a washing machine to full capacity for washing clothes. 

We should not let the tap run while washing hands and face. 

We should water plants in the evening or early morning to minimise evaporation.

We should make provisions to store rainwater on rooftops and reuse the water for household purposes.

Bigger Communities and farmers should adapt to the practice of Rainwater harvesting. 

The industrial waste should be treated properly instead of dumping it into rivers.

We should stop using plastics and dispose of them in an adequate way.

We can make people aware about water problems by means of social campaigns and other ways.

 We should educate our children about water saving from an early age. 

Reusing the water is an important way to save and prevent the scarcity of water. Bathing water can be recycled and used for planting or cleaning.

Rainwater harvesting is the method of collecting rainwater and conserving them for future use.

Conservation of groundwater is another important method in the preservation of groundwater and using it in the future.

 Prevention of waterlogging.

We cannot imagine our lives without water. It is unfortunate that mankind has neglected this precious gift from God. Conservation of water is a necessity to save life. All living organisms on this planet need water to survive. If we do not give importance to saving or conservation of water then our future generations will face water scarcity.


FAQs on Save Water Save Life Essay

1. How to minimise wasting water?

We can minimise wasting water by using only the required amount of water.    We should not let the tap run while washing hands and face. Furthermore, checking for leaks in pipelines and getting them resolved in time and taking shorter baths and reducing the use of showers can also help.

2. When is World Water Day celebrated and why?

World Water Day is celebrated on 22nd March every year. It is celebrated to remind us of the importance of water and how we should minimise wastage of water.

3. Why is it important to save water?

It is important to save water because only 3% of available water is freshwater. Water is vital for the sustenance of living beings on this planet. If we don’t use water properly then our future generations will face the scarcity of water.

4. What methods should farmers adopt for irrigation?

The farmers should stop using pesticides and chemical fertilisers to minimise    pollution in water and adapt to the method of Rainwater harvesting.

5. How to save water daily?

We should close the tap tightly after use, use the required amount of water, check the water level in the tanks, and stop them from overflowing, making rainwater harvesting tunnels to save and reuse rainwater after its purification. These are some basic steps to save water at an individual level.

6. Where can I find more information on water and how to save water?

You can find more information, along with answers to your commonly asked questions, on the Vedantu website and mobile app. So, browse through them to get all your questions answered easily.

Dehydration and Importance of Water Essay

Introduction, importance of water in health maintenance, functions of water in the body, what happens to the body when there isn’t enough water, how different electrolytes function in the body, effects of alcohol and caffeine on hydration levels in the body, steps to be taken to ensure that one does not become dehydrated.

Water is a chemical compound that exists as a liquid in the body. It is a crucial part of the body systems and has even been called ‘the liquid of life.’

Water has been known to prevent a number of illnesses hence restoring ones health. Most of these illnesses are; cancer of the colon, breast and the lungs. Drinking water may not necessarily eliminate the possibility of getting these cancers; it simply reduces the probability of their occurrence.

Due to the crucial role played by water, lack of it causes some immediate symptoms. First of all, one experiences headaches and fatigue. Subsequently, one may loose part of their memory and may have trouble remembering small things. Water ensures that one does not have trouble concentrating because it is said that absence of water reduces one’s concentration span. (Kent, 1997)

Constipation is prevented by water. This is done through easing digestion by providing a solvent in which the toxins can dissolve.

Water is said to be the perfect moisturizer for our skin and prevents patchiness. It is also used to control one’s emotions.

Water has numerous bodily functions. Perhaps its most important is the fact that it is a constituent of most cells, organs and systems in the body. It is a fact that water makes up about 90% of the lungs, over ninety percent of the brain and about eighty percent of blood. There are plenty of fluids in the body that mainly consist of water; one of these is saliva.

Water is used to protect the interior organs from external shock. One such organ is the heart. In line with this role, water makes up most of the fluid that is found in between joints, as such, it is used as a lubricant to ease bodily movements.

Transportation in the body is mainly done by water. It transports waste products from their areas of production such as the kidneys to the external environment. It therefore gets rid of toxins from the body. Water also transports oxygen from the lungs to other parts of the body that are in need of it. Nutrients are also transported by water from the digestive system to muscles and other body parts in need of it.

Temperature regulation is another very important function of water. It acts as a kind of thermostat in the body. When body temperature exceeds optimum levels, the body sweats. Sweat mainly consists of water which normally leaves with a lot of heat when it evaporates thus cooling the body. This property of water is called high latent heat of vaporization.

Water is used for detoxification purposes by getting rid of wastes that are carried by the intestinal tract. As such it ensures that the body is in great health.

Lack of water in the body causes thirst. This is incase the amount of water under consideration is a small amount. The thirst then graduates to a more uncomfortable symptom; fatigue. One’s body feels restless and inactive. Eventually, headaches set in as the brain is now complaining. If the condition persists, then dizziness sets in and eventually one complains of feeling heaviness in their head. These are all signs of dehydration.

When the body is constantly denied access to water, reverse osmosis occurs. Instead of water leaving the body and getting filtered into the brain cells, the opposite occurs. Water leaves the cells and enters the system. This means that the body develops an elevated blood pressure since it is going against the norm. High blood pressure can be disastrous if allowed to continue without checking it.

There are some emotional manifestations of a lack of water in the body. One who has not had a lot of water is normally quite irritable and moody. They are quick to anger and are full of impatience.

Constant dehydration also causes a number of illnesses that may be fatal. Some of these include; weak immunity, hypertension and the very dangerous diabetes.

Sodium is mostly obtained from salt which is a compound made of both sodium and chlorine. It is put to use in the nervous systems during transportation of a message from one part of the body to another or from the external environment to the body. These messages may include; pain, heat and electric shock. There is a need for proper electrolyte balance within the body for any stimulant to be recorded well by the body.

Potassium is used to control the sodium balance within the body to ensure that metabolic systems function well. Chlorine serves to neutralize sodium because it is negatively charged while sodium is a positively charged ion. The two complement each other and thus chlorine maintains adequate balance in the body.

There’s a hormone in the body that is responsible for absorption of water back from the kidneys. It is called vasopressin. This hormone helps the body to maintain a balance of water thus preventing excessive loss. Consumption of alcohol causes a depression of Vasopressin meaning that plenty of water will not be reabsorbed and most of it will go to waste as urine. (Ellen, 1980)

Alcohol also causes severe loss in nutrients that are quite important to the body. These nutrients include; calcium, zinc, potassium and sodium. This in turn affects the body’s nervous system and balance of fluids.

It causes prolonged dehydration; this was shown in a research where people’s blood was tested. Most of them were found to have thicker blood especially due to frequent urination.

Caffeine also lowers levels of hydration. This happens by dieresis which is the process of excess absorption of water from blood in the kidneys. Caffeine also inhibits the reabsorption of sodium hence interrupting the hydration process.

The first step is to drink plenty of water. Doctors advise us to take about 8 glasses of water per day. This will ensure proper physical and psychological health.

One should avoid alcohol and caffeinated drinks. This is because the latter mentioned substances enhance the loss of water through the kidneys and must be kept at a minimum or avoided altogether (Barbara, 2004).

If one engages in heavy activities, then one should not wear heavy clothes because they increase the rate at which a body is sweating. The more one sweats, the more the fluid they loose from the body and the more the chances of dehydration.

There are some tell – tale signs that come with hydration. Individuals must learn to recognize them as soon as possible and to do something about them. These include; patchy or dry lips, thick urine, heavy eyes and mild headaches.

Individuals must also protect themselves from excessive sunshine which brings about sweatiness hence water loss from the body. They can do this by standing under a shade when exposed.

Water represents life. Water is a precious resource, a fundamental human requirement, and a valuable asset that all living things possess. Every child should understand the importance of water in daily life.

There are many reasons why water is considered one of the most important and valuable resources on our planet. Let us look at this in a more detailed manner.

Significance Of Water

Water is the cornerstone of human survival when it comes to life. A human body requires water every single day. We might be capable of not eating for seven days; however, we won’t last even three days without drinking water. Furthermore, approximately 60% of human bodies are made up of water which aids our body’s normal functioning. As a result, ingesting impure water will cause major health issues in humans. Therefore, the amount and quality of water we drink are critical to everyone’s physical health and wellness.

Furthermore, our everyday activities would be incomplete without water, like brushing our teeth or preparing meals. Also, many companies use water on a massive scale as almost every single activity of their procedure requires water.

Water has an important function in the lives of all living organisms. From the tiniest insect to the largest whale, each life requires water to stay alive. Water is not just a human need but also flora and fauna. Water is necessary for the planet’s life to function. We should not be self-centred and utilise it for our purposes without caring for the consequences.

Water For Life Processes

  • Water plays a crucial part in most biological functions as a solvent. Several waste materials are also eliminated as a solution via urination and sweat.
  • Water aids in maintaining body temperature. We take plenty of fluids when it’s hot outside, which keeps the body temperature stable. Water also escapes from the body’s surface as sweat, which removes heat from the body and gets to normal temperature.
  • Water is required for plants to make food.

Uses Of Water

  • In our daily lives, water is utilised for drinking, dishwashing, baking, showering, and wiping.
  • We need water daily for our home gardens too.
  • A hydroelectric power plant uses water to create energy.
  • Water is being used to irrigate crops and create a variety of items.
  • Many water sports include swimming, sailing, kayaking, etc.
  • Water can also be used to put out fires.
  • Water is necessary for the correct operation of farmed fish, dairies, and many other non-farm operations.
  • The majority of fresh water is frozen.
  • The oceans contain just about all the water on the planet.
  • The salt content of salty water fluctuates.
  • One single drop could hold a great deal of life.
  • Comets might have also provided some water in the earth’s history. 

Your child will learn how to improve their writing and creative abilities. They will also discover how important water is for their bodies and the ecosystem and the various ways they might use it. They will learn about the importance of water on this planet, not just for humans but for all living things. Last but not least, students will learn about several water-related facts.

1. What Will Happen If Water Vanishes?

Complete vegetation would die rapidly without water, making the earth brown instead of greenish-blue. As clouds will fail to develop and there will be no rainfall, the climate will be dominated entirely by atmospheric circulation. Life as we know it would cease to exist. 

2. Why Should We Not Waste Water?

Water is scarce, despite its abundance, and cannot be regenerated. We must utilise it with caution.

To summarise, water is indeed the foundation of all living things on the planet. Recognising fresh water’s importance and educating people about it is necessary.

Importance of Water Essay

Essay on Importance of Water

Water is a critical and life-supporting resource for life on Earth. It is essential for the survival of all living organisms, including humans. In addition to being a vital component of our bodies, water is also necessary for various other purposes from our day-to-day activities and maintaining the climatic conditions. Water has various functions and is important in maintaining a healthy ecosystem. Without water, no living organisms can survive and because of this, only our planet can support life. The presence of Water is what gives our planet its name of ‘Blue Planet’. About 70% of our earth is filled with water.

Water is a crucial component and life maintaining resource of the human body as water constitutes around 60% of an adult human body and plays a vital role in maintaining bodily functions. It regulates our temperature, transports nutrients, and oxygen to cells, removes waste products and maintains overall health. Our blood is made up of water with this only circulation of other major and important elements takes place. In fact our cells the smallest constituent of the human body are made up of water. Our bodies without water can not function. That’s why drinking sufficient amounts of water is essential to keep our bodies hydrated, which can help prevent dehydration, heat stroke, and other related illnesses.


Not only for humans but water is essential for all living organisms like plants, trees and marine organisms. Water is not just essential for living but it also forms an ecosystem. Water forms many ecosystems like ocean ecosystems, river ecosystems, and lake and pond ecosystems. All these ecosystems support various forms of life from plants to organisms including microorganisms. With the evolution of these organisms, only terrestrial organisms evolved. So if it was not for water no life would have evolved millions of years back on the earth and we would be like every other planet lifeless and barren.

Aside from this water is also essential for the environment. It plays a crucial role in maintaining the balance of ecosystems, including rivers, lakes, and oceans. It helps to regulate the water cycle in the environment among different water bodies. Due to this water cycle climatic conditions are maintained. Distribution of water occurs due to this which also helps to maintain the temperature of Earth. Water helps to regulate the temperature of the environment, acting as a natural coolant. Without sufficient water, ecosystems can become imbalanced, leading to droughts, famines, and other environmental disasters. Water is necessary for the growth of plants, which provide food and habitat for wildlife also.

Flora and Fauna of any region are maintained because of water. Water is necessary for plants as without it photosynthesis will not take place and without photosynthesis oxygen will not be released and carbon dioxide will not be taken up by plants both of which are necessary for the survival of any living organisms. Plants are the ultimate source of food for other organisms and without food, no one can survive. Water is also critical to agriculture, which is a primary source of food for many people around the world. Crops grown by humans as food require water to grow, and without sufficient amounts of water, there will be no yields and which directly affects humans.

Water is important in many industries also, including manufacturing and mining, which require large amounts of water to operate. Due to the excessive use of water, the water bodies are getting polluted. Contaminated water can pollute the nearby rivers and lakes, making it difficult for the survival of plants and wildlife. In fact contaminated water is a threat to humans also and if consumed can cause many diseases and even death. Additionally, water is a valuable resource for recreation. Lakes, rivers, and oceans provide opportunities for swimming, boating, and fishing. These activities not only provide a source of enjoyment for people but also contribute to the tourism industry, creating jobs and economic benefits.

Humans are dependent on water not for their biological need but for their economical needs also. Despite the many benefits of water and the huge amount of it present on the earth’s surface, we have to remember that it is a finite resource. Only a small percentage of the Earth’s water is suitable for human consumption, and much of it is already polluted or contaminated. In many parts of the world, access to clean and safe water is limited, leading to water shortages and related health issues. As the global population continues to grow, the demand for water is also increasing, making it essential to manage this resource responsibly.

In conclusion, water is a crucial resource that is essential for life on Earth. It is necessary for human health, maintaining ecosystems, agriculture, industrial processes, and recreation. However, water is a finite resource that requires responsible management to ensure its availability for future generations. It is essential to conserve water resources and prevent contamination to ensure that this vital resource remains available to all.

  • October 9, 2021

importance of water for life essay

Water is one of the most important things for our life. It is necessary for all living beings and it is also a necessity for human body to survive. There are many ways in which we can use water to make our lives easier, but there are some other ways in which we can use it as well.

Importance of water in our life essay. Water is an essential part of our life and we need to take care of it.

We all understand the significance of water in our lives, but just to clarify, water is something that all humans need to survive in this planet. If the earth’s water supply is entirely depleted, the human species will be extinct within a day. Well, water is utilized for a variety of reasons and for a variety of things . Here are a few examples of the many applications we utilize in our daily lives.

The act of drinking water is what keeps a person alive. People would certainly consider and make themselves more comfortable for the period if they do not drink water for more than 12 hours. Water consumption is a healthy habit that all physicians suggest. A typical individual should drink at least 2 to 3 liters of water each day.

We all want a clean environment to live in and visit. However, we all know that water is required for any kind of cleaning. We need water to keep our clothing neat and clean, ware to keep our floors clean, and water to keep our toilets clean . As a result, water is required for every requirement that arises in your everyday activity.

What does wish to do well after drinking and cleaning is something that is needed not only for humans but also for animals and plants. Plants can’t develop without water, therefore if a farmer doesn’t receive water in a timely manner, his crop will be lost in 2 to 3 days. The farmer may simply produce veggies with the assistance of water.

The majority of people have no idea what the water cycle is. Also, how can we obtain water from the sky? Well, it’s quite simple; we’ve all learned in school that clouds contain water, but how do the clouds get this water?

This water cycle is maintained with the assistance of the sun. For example, the sun warms the water, which causes it to evaporate. Once evaporated, the water condenses into a cloud, which then travels to the city center and rains.

There are two major sources of water: surface water and groundwater. Let’s speak about surface water for a moment; most people are familiar with it. Surface water may be found in rivers, lakes, and the ocean, and it raises a voice that is utilized by humans to transport and survive for their lives.

Now it’s time to speak about groundwater. Ground water is water that is found under the earth’s surface. People discover this groundwater and begin to use it. No one knows how groundwater came to be, but as people start learning about it, they realize that most rivers are also linked to the ground from the surface, thus it is in some way related to the oceans for water.

Water is a very important part of our life. It is the most essential resource for human beings and it comes from rain, rivers, lakes, etc. Reference: essay on importance of water for class 4 .

250 Words Essay on Water Is Life


Water, a simple molecule composed of two hydrogen atoms and one oxygen atom, is the lifeblood of our planet. It is the most abundant and essential resource, without which life as we know it would not exist.

The Essence of Life

Water is the fundamental building block of life. It is involved in every bodily function, from digestion and circulation to temperature regulation and waste removal. The human body is approximately 60% water, reflecting its importance in maintaining life and health.

Water and the Environment

Water’s role extends beyond the individual organism. It is integral to maintaining Earth’s delicate ecosystems. Water cycles through our environment, from the atmosphere to the earth and back again, supporting plant and animal life, shaping landscapes, and influencing climate patterns.

The Social and Economic Impact of Water

Water also plays a significant role in social and economic structures. It is vital for agriculture, industry, and energy production. Access to clean water is a determinant of societal health and prosperity. Yet, water scarcity, pollution, and mismanagement pose major challenges, with profound implications for human rights, social equity, and global stability.

In conclusion, water is life. It is the essence of biological function, the driver of ecological systems, and the underpinning of social and economic structures. As we face a future of increasing water scarcity and pollution, understanding and respecting the critical role of water is more important than ever. We must strive to conserve and protect this invaluable resource, for it is not just water, but life itself.

500 Words Essay on Water Is Life

The essence of life: water.

Water, the most vital natural resource, is the lifeblood of every living organism on Earth. From microscopic organisms to the largest mammals, all life forms depend on water for survival. This universal solvent, often referred to as the “elixir of life,” performs essential roles in biological processes, climatic regulation, and economic development.

Water: The Biological Imperative

Water is crucial to the existence and sustenance of life on Earth. It comprises about 60-70% of a human body, acting as a medium for biochemical reactions, a transporter of nutrients and waste, and a temperature regulator. It is the primary component of cells, tissues, and organs, and without it, life as we know it would cease to exist.

In the plant kingdom, water is instrumental for photosynthesis, the process by which plants produce food. It also facilitates the transportation of nutrients from the roots to other parts of the plant. Hence, the absence of water would disrupt the food chain, leading to catastrophic effects on all life forms.

Water and Climate

Water plays a significant role in regulating Earth’s climate. The hydrological cycle, involving evaporation, condensation, precipitation, and runoff, is a key driver of weather patterns. Oceans, which hold about 97% of Earth’s water, absorb heat from the sun and distribute it around the globe through ocean currents, thereby moderating global temperatures.

Furthermore, water in the form of ice at the poles and high altitudes reflects sunlight back into space, helping to stabilize Earth’s temperature. The melting of this ice due to global warming is a cause for concern as it could lead to a rise in sea levels and drastic changes in climate.

Economic Importance of Water

Water is indispensable for economic development. It is essential for agriculture, which is the primary source of livelihood for a large portion of the global population. Industries such as power generation, manufacturing, and tourism also rely heavily on water. Moreover, waterways serve as important routes for trade and transportation, contributing significantly to the global economy.

Water Scarcity and Conservation

Despite its abundance, water scarcity is a pressing issue in many parts of the world due to factors like overpopulation, overexploitation, pollution, and climate change. This underscores the need for efficient water management and conservation.

Water conservation can be achieved through strategies like rainwater harvesting, recycling and reusing wastewater, and adopting water-efficient technologies. It is also crucial to create awareness about the importance of water and the need for its conservation.

In conclusion, water is not just a life-sustaining resource but the very essence of life. It is a critical component of biological processes, a key climate regulator, and an economic catalyst. However, the growing water scarcity necessitates urgent action to conserve and manage this invaluable resource. As we recognize water’s integral role in our lives, it becomes our collective responsibility to ensure its availability for future generations. After all, water is life.

An Essay on Importance of water

An Essay on Importance of water in life (1000 words)


Water is one of the most abundant substances on Earth and yet it takes a lot of work to obtain, purify, and distribute. Clean drinking water is essential for life but many people don’t have access to clean water.

Importance of water for human body

Water is a necessary resource for all living organisms. It is the most abundant molecule on Earth and forms about 60% of the human body, but many people do not realize how important it really is.

The human body cannot function without water because it regulates core temperature, transports nutrients to cells, and excretes waste. There are also several other benefits to drinking plenty of water: improved skin tone, weight loss support, increased metabolism rate, better elimination process in the colon or kidneys among others.

Water should be drunk at least eight 8-ounce glasses per day (or 64 ounces). If you find yourself feeling hungry after only drinking that much water in a day then you might need more salt in your diet.

Importance of water in life

Water is the most important substance on Earth. It covers more than 70% of the Earth’s surface and enables life to exist as we know it. Water is also a vital resource for sustaining our planet. We cannot survive without water. The world’s population has never been so dependent on water as it is today.

Water is the most vital resource that sustains all living beings and its importance cannot be overstated. Without water, life simply couldn’t exist on earth. But due to pollution as well as climate change issues such as droughts and floods, we are now experiencing critical shortages of this natural resource that humans need for survival. It is time for us to start conserving more with regards to water usage in order to ensure that future generations will have enough clean fresh water available for their needs.

Uses of Water

Water is one of the most important resources on Earth. Water is used in many ways. It can be utilized for: drinking, bathing, cooking, and cleaning. In addition to these uses of water, it is also one of the most important sources of energy in the world.

Water is probably the most useful substance known to man. It’s a solvent, a lubricant, an aid to digestion, a purifier, and a transportation medium, which means it’s not only an ingredient in the things you put on your skin but it’s also something you’re putting on your skin.

Shortage of clean water

Globally, 1.2 billion people live without clean or safe water. The health of populations and economies are inextricably linked to the provision of adequate water supply. Water is a public health issue as it relates to human well-being, the economy, and the environment. Water quality is also affected by the complex interactions of climate change, pollution, and land-use change.

It has been estimated that 3 out 5 people on Earth lives without access to clean drinking water or adequate sanitation facilities which causes disease and death every day (World Health Organization). The lack of clean drinking water leads to illnesses such as diarrhea, malaria, and typhoid fever (WHO) . The World Bank estimates that poor hygiene practices lead to 2 million deaths per year due to diarrheal diseases.

How to avoid wastage of water

There are many ways you can conserve water in your home such as installing a low-flow showerhead, taking shorter showers, or recycling greywater. The first step is knowing how much you use on a day-to-day basis so that you know where you can start conserving the most. Once this has been done it is easier for us to make changes and save more! You could try asking yourself these questions: do I have leaky faucets? Do I regularly leave my taps running while washing dishes?

Considering how much we use it in our day-to-day lives, wasting water can be incredibly costly – not just in monetary terms but also with regard to the environment. There’s one simple thing you can do right now to help conserve this precious resource: turn off your taps when you brush your teeth! Every time you leave them running while brushing your teeth – which happens every morning – it wastes around two liters.

How important is water in your life?

Every year, on March 22, people around the world celebrate World Water Day. This day is dedicated to raising awareness about the importance of water in our lives, and the need to protect this precious resource for future generations.

We need to change the way we think about water. Its true cost, from an economic, social, and environmental perspective, must be incorporated into the entire life cycle of any undertaking: personal, professional, industrial, or environmental.

Water is essential for all forms of life. It’s a basic human need, and access to clean water is a fundamental human right. Unfortunately, many people still lack clean and safe access, putting their health at risk.

Water is also crucial for agriculture and food production, as well as for industry and energy production. Without water, we could not grow crops or produce the goods and services that we rely on every day. Without water, lithium batteries essential to electrification cannot be produced. Water is not only essential for creating goods and materials but also for sustaining our world. Proper management of industrial water and wastewater is critical for environmental sustainability and business continuity.

Many in developed countries have access to clean water at the turn of a tap, without giving a second thought to where it comes from or how it is treated. We use water for everything from cooking and cleaning to watering our lawns and filling our swimming pools, without realizing the impact our actions have on the environment and on others who may not have access to the same resources.

This World Water Day, let us take a moment to reflect on the importance of water in our lives, and the need to protect this resource for future generations. Let us also remember those who are still struggling to access clean water and do what we can to support efforts to provide safe and sustainable water sources for all.

We can all make a difference by conserving water, reducing our water usage, and supporting organizations that work to provide access to clean water in underserved communities. By working together, we can ensure that everyone has access to the clean, safe water they need to thrive.

How Hatch is making a difference

Urban development strategies must account for the effects that high density precipitation and flash floods will have on new housing developments, energy access, transportation, communications, and other community-related infrastructure. The integrity and potential redesign of existing infrastructure such as roads, communication corridors, drainage systems, energy and water distribution must also be evaluated, along with the way consumers use and reuse water.

Here’s a few examples of how Hatch is helping communities better manage their water resources.

Potomac River Tunnel, Washington DC, USA

The next big phase of the DC Clean Rivers Project is the Potomac River Tunnel. Hatch and its partners will use their extensive experience in water tunnel construction and creative solutions to make this project happen.

The project is a 5.5-mile-long tunnel that will help control combined sewer overflows into the Potomac River. This will improve the water quality of this important natural resource and will aim to make the water quality better in the Anacostia and Potomac Rivers and Rock Creek. This project will have a significant impact on reducing combined sewer overflows and play a key role in making the environment more sustainable for the region.

To learn more about this project – go to: Potomac Tunnel project underway: CBNA, Halmar, COWI, & Hatch join forces.


Xhora Water Storage Dam, Elliotdale, Eastern Cape, South Africa

Hatch is working with the Amathole District Municipality to deliver the Xhora Water Supply Scheme. The scheme's first phase includes a river intake, as well as an off-channel storage dam, water treatment works, 190 km of bulk pipelines with five pump stations, 48 reservoirs and 700 km of distribution.

The Off-Channel Storage Dam is essential for providing the Xhora Water Supply Scheme with reliable drinking water for 70,000 people. It is in a small part of the river basin and is designed to reduce environmental impacts. It was important to make sure the environmental instream flow requirements were satisfied for both the tributary where the dam was built and the river with the intake. The project has received a commendation in the Technical Excellence Project category at the SANRAL SAICE National Awards 2021 in South Africa.

To learn more about this project – go to: Xhora Off-Channel Storage Dam (hatch.com)

Lakeshore Water Wastewater Plant, Canada

Hatch was engaged to provide engineering and construction services for the town of Innisfil in Ontario, Canada, which needed additional wastewater treatment capacity for future growth. This included many vital services, assessments, and designs that our Hatch experts oversaw during the design and construction stages. This was done while ensuring extensive and crucial efforts were being made to minimize the negative impact on this area, as the Lakeshore Wastewater Treatment Plant is located within a regulated area of wetlands and woodlands.

These challenges were met with solutions that minimally impacted the environment, reduced leakage, introduced new and innovative approaches, and maximized the use of important materials, all while engaging local employees and investing millions in local wages and contractors.

World Water Day serves as a crucial reminder of the importance of water conservation and sustainable management. Investing in water projects not only fulfills our social responsibility at Hatch, but also secures a vital resource and helps contribute to a more sustainable world for generations to come.

The Great Rupture in American Jewish Life

Credit... Daniel Benneworth-Gray

Supported by

By Peter Beinart

Mr. Beinart is the editor at large of Jewish Currents and a journalist and writer who has written extensively on the Middle East, Jewish life and American foreign policy.

  • March 22, 2024

F or the last decade or so, an ideological tremor has been unsettling American Jewish life. Since Oct. 7, it has become an earthquake. It concerns the relationship between liberalism and Zionism, two creeds that for more than half a century have defined American Jewish identity. In the years to come, American Jews will face growing pressure to choose between them.

They will face that pressure because Israel’s war in Gaza has supercharged a transformation on the American left. Solidarity with Palestinians is becoming as essential to leftist politics as support for abortion rights or opposition to fossil fuels. And as happened during the Vietnam War and the struggle against South African apartheid, leftist fervor is reshaping the liberal mainstream. In December, the United Automobile Workers demanded a cease-fire and formed a divestment working group to consider the union’s “economic ties to the conflict.” In January, the National L.G.B.T.Q. Task Force called for a cease-fire as well. In February, the leadership of the African Methodist Episcopal Church, the nation’s oldest Black Protestant denomination, called on the United States to halt aid to the Jewish state. Across blue America, many liberals who once supported Israel or avoided the subject are making the Palestinian cause their own.

This transformation remains in its early stages. In many prominent liberal institutions — most significantly, the Democratic Party — supporters of Israel remain not only welcome but also dominant. But the leaders of those institutions no longer represent much of their base. The Democratic majority leader, Senator Chuck Schumer, acknowledged this divide in a speech on Israel on the Senate floor last week. He reiterated his longstanding commitment to the Jewish state, though not its prime minister. But he also conceded, in the speech’s most remarkable line, that he “can understand the idealism that inspires so many young people in particular to support a one-state solution” — a solution that does not involve a Jewish state. Those are the words of a politician who understands that his party is undergoing profound change.

The American Jews most committed to Zionism, the ones who run establishment institutions, understand that liberal America is becoming less ideologically hospitable. And they are responding by forging common cause with the American right. It’s no surprise that the Anti-Defamation League, which only a few years ago harshly criticized Donald Trump’s immigration policies, recently honored his son-in-law and former senior adviser, Jared Kushner.

Mr. Trump himself recognizes the emerging political split. “Any Jewish person that votes for Democrats hates their religion,” he said in an interview published on Monday. “They hate everything about Israel, and they should be ashamed of themselves because Israel will be destroyed.” It’s typical Trumpian indecency and hyperbole, but it’s rooted in a political reality. For American Jews who want to preserve their country’s unconditional support for Israel for another generation, there is only one reliable political partner: a Republican Party that views standing for Palestinian rights as part of the “woke” agenda.

The American Jews who are making a different choice — jettisoning Zionism because they can’t reconcile it with the liberal principle of equality under the law — garner less attention because they remain further from power. But their numbers are larger than many recognize, especially among millennials and Gen Z. And they face their own dilemmas. They are joining a Palestine solidarity movement that is growing larger, but also more radical, in response to Israel’s destruction of Gaza. That growing radicalism has produced a paradox: A movement that welcomes more and more American Jews finds it harder to explain where Israeli Jews fit into its vision of Palestinian liberation.

The emerging rupture between American liberalism and American Zionism constitutes the greatest transformation in American Jewish politics in half a century. It will redefine American Jewish life for decades to come.

A photograph of a group of people in front of the Capitol building. One woman holds a sign that says “Jews say: Ceasefire Now.” Another person holds a sign that says “No to war, no to apartheid.”

“A merican Jews,” writes Marc Dollinger in his book “Quest for Inclusion: Jews and Liberalism in Modern America,” have long depicted themselves as “guardians of liberal America.” Since they came to the United States in large numbers around the turn of the 20th century, Jews have been wildly overrepresented in movements for civil, women’s, labor and gay rights. Since the 1930s, despite their rising prosperity, they have voted overwhelmingly for Democrats. For generations of American Jews, the icons of American liberalism — Eleanor Roosevelt, Robert Kennedy, Martin Luther King Jr., Gloria Steinem — have been secular saints.

The American Jewish love affair with Zionism dates from the early 20th century as well. But it came to dominate communal life only after Israel’s dramatic victory in the 1967 war exhilarated American Jews eager for an antidote to Jewish powerlessness during the Holocaust. The American Israel Public Affairs Committee, which was nearly bankrupt on the eve of the 1967 war, had become American Jewry’s most powerful institution by the 1980s. American Jews, wrote Albert Vorspan, a leader of Reform Judaism, in 1988, “have made of Israel an icon — a surrogate faith, surrogate synagogue, surrogate God.”

Given the depth of these twin commitments, it’s no surprise that American Jews have long sought to fuse them by describing Zionism as a liberal cause. It has always been a strange pairing. American liberals generally consider themselves advocates of equal citizenship irrespective of ethnicity, religion and race. Zionism — or at the least the version that has guided Israel since its founding — requires Jewish dominance. From 1948 to 1966, Israel held most of its Palestinian citizens under military law; since 1967 it has ruled millions of Palestinians who hold no citizenship at all. Even so, American Jews could until recently assert their Zionism without having their liberal credentials challenged.

The primary reason was the absence from American public discourse of Palestinians, the people whose testimony would cast those credentials into greatest doubt. In 1984, the Palestinian American literary critic Edward Said argued that in the West, Palestinians lack “permission to narrate” their own experience. For decades after he wrote those words, they remained true. A study by the University of Arizona’s Maha Nassar found that of the opinion articles about Palestinians published in The New York Times and The Washington Post between 2000 and 2009, Palestinians themselves wrote roughly 1 percent.

But in recent years, Palestinian voices, while still embattled and even censored , have begun to carry. Palestinians have turned to social media to combat their exclusion from the press. In an era of youth-led activism, they have joined intersectional movements forged by parallel experiences of discrimination and injustice. Meanwhile, Israel — under the leadership of Benjamin Netanyahu for most of the past two decades — has lurched to the right, producing politicians so openly racist that their behavior cannot be defended in liberal terms.

Many Palestine solidarity activists identify as leftists, not liberals. But like the activists of the Occupy Wall Street and Black Lives Matter movements, they have helped change liberal opinion with their radical critiques. In 2002, according to Gallup , Democrats sympathized with Israel over the Palestinians by a margin of 34 points. By early 2023, they favored the Palestinians by 11 points. And because opinion about Israel cleaves along generational lines, that pro-Palestinian skew is much greater among the young. According to a Quinnipiac University poll in November, Democrats under the age of 35 sympathize more with Palestinians than with Israelis by 58 points.

Given this generational gulf, universities offer a preview of the way many liberals — or “progressives,” a term that straddles liberalism and leftism and enjoys more currency among young Americans — may view Zionism in the years to come. Supporting Palestine has become a core feature of progressive politics on many campuses. At Columbia, for example, 94 campus organizations — including the Vietnamese Students Association, the Reproductive Justice Collective and Poetry Slam, Columbia’s “only recreational spoken word club” — announced in November that they “see Palestine as the vanguard for our collective liberation.” As a result, Zionist Jewish students find themselves at odds with most of their politically active peers.

Accompanying this shift, on campus and beyond, has been a rise in Israel-related antisemitism. It follows a pattern in American history. From the hostility toward German Americans during World War I to violence against American Muslims after Sept. 11 and assaults on Asian Americans during the Covid pandemic, Americans have a long and ugly tradition of expressing their hostility toward foreign governments or movements by targeting compatriots who share a religion, ethnicity or nationality with those overseas adversaries. Today, tragically, some Americans who loathe Israel are taking it out on American Jews. (Palestinian Americans, who have endured multiple violent hate crimes since Oct. 7, are experiencing their own version of this phenomenon.) The spike in antisemitism since Oct. 7 follows a pattern. Five years ago, the political scientist Ayal Feinberg, using data from 2001 and 2014, found that reported antisemitic incidents in the United States spike when the Israeli military conducts a substantial military operation.

Attributing the growing discomfort of pro-Israel Jewish students entirely to antisemitism, however, misses something fundamental. Unlike establishment Jewish organizations, Jewish students often distinguish between bigotry and ideological antagonism. In a 2022 study , the political scientist Eitan Hersh found that more than 50 percent of Jewish college students felt “they pay a social cost for supporting the existence of Israel as a Jewish state.” And yet, in general, Dr. Hersh reported, “the students do not fear antisemitism.”

Surveys since Oct. 7 find something similar. Asked in November in a Hillel International poll to describe the climate on campus since the start of the war, 20 percent of Jewish students answered “unsafe” and 23 percent answered “scary.” By contrast, 45 percent answered “uncomfortable” and 53 percent answered “tense.” A survey that same month by the Jewish Electorate Institute found that only 37 percent of American Jewish voters ages 18 to 35 consider campus antisemitism a “very serious problem,” compared with nearly 80 percent of American Jewish voters over the age of 35.

While some young pro-Israel American Jews experience antisemitism, they more frequently report ideological exclusion. As Zionism becomes associated with the political right, their experiences on progressive campuses are coming to resemble the experiences of young Republicans. The difference is that unlike young Republicans, most young American Zionists were raised to believe that theirs was a liberal creed. When their parents attended college, that assertion was rarely challenged. On the same campuses where their parents felt at home, Jewish students who view Zionism as central to their identity now often feel like outsiders.

In 1979, Mr. Said observed that in the West, “to be a Palestinian is in political terms to be an outlaw.” In much of America — including Washington — that remains true. But within progressive institutions one can glimpse the beginning of a historic inversion. Often, it’s now the Zionists who feel like outlaws.

G iven the organized American Jewish community’s professed devotion to liberal principles, which include free speech, one might imagine that Jewish institutions would greet this ideological shift by urging pro-Israel students to tolerate and even learn from their pro-Palestinian peers. Such a stance would flow naturally from the statements establishment Jewish groups have made in the past. A few years ago, the Anti-Defamation League declared that “our country’s universities serve as laboratories for the exchange of differing viewpoints and beliefs. Offensive, hateful speech is protected by the Constitution’s First Amendment.”

But as pro-Palestinian sentiment has grown in progressive America, pro-Israel Jewish leaders have apparently made an exception for anti-Zionism. While still claiming to support free speech on campus, the A.D.L. last October asked college presidents to investigate local chapters of Students for Justice in Palestine to determine whether they violated university regulations or state or federal laws, a demand that the American Civil Liberties Union warned could “chill speech” and “betray the spirit of free inquiry.” After the University of Pennsylvania hosted a Palestinian literature festival last fall, Marc Rowan, chair of the United Jewish Appeal-Federation of New York and chair of the board of advisers of Penn’s Wharton business school, condemned the university’s president for giving the festival Penn’s “imprimatur.” In December, he encouraged trustees to alter university policies in ways that Penn’s branch of the American Association of University Professors warn ed could “silence and punish speech with which trustees disagree.”

In this effort to limit pro-Palestinian speech, establishment Jewish leaders are finding their strongest allies on the authoritarian right. Pro-Trump Republicans have their own censorship agenda: They want to stop schools and universities from emphasizing America’s history of racial and other oppression. Calling that pedagogy antisemitic makes it easier to ban or defund. At a much discussed congressional hearing in December featuring the presidents of Harvard, Penn and M.I.T., the Republican representative Virginia Foxx noted that Harvard teaches courses like “Race and Racism in the Making of the United States as a Global Power” and hosts seminars such as “Scientific Racism and Anti-Racism: History and Recent Perspectives” before declaring that “Harvard also, not coincidentally but causally, was ground zero for antisemitism following Oct. 7.”

Ms. Foxx’s view is typical. While some Democrats also equate anti-Zionism and antisemitism, the politicians and business leaders most eager to suppress pro-Palestinian speech are conservatives who link such speech to the diversity, equity and inclusion agenda they despise. Elise Stefanik, a Trump acolyte who has accused Harvard of “caving to the woke left,” became the star of that congressional hearing by demanding that Harvard’s president , Claudine Gay, punish students who chant slogans like “From the river to the sea, Palestine will be free.” (Ms. Gay was subsequently forced to resign following charges of plagiarism.) Elon Musk, who in November said that the phrase “from the river to the sea” was banned from his social media platform X (formerly Twitter), the following month declared , “D.E.I. must die.” The first governor to ban Students for Justice in Palestine chapters at his state’s public universities was Florida’s Ron DeSantis, who has also signed legislation that limits what those universities can teach about race and gender.

This alignment between the American Jewish organizational establishment and the Trumpist right is not limited to universities. If the A.D.L. has aligned with Republicans who want to silence “woke” activists on campus, AIPAC has joined forces with Republicans who want to disenfranchise “woke” voters. In the 2022 midterm elections, AIPAC endorsed at least 109 Republicans who opposed certifying the 2020 election. For an organization single-mindedly focused on sustaining unconditional U.S. support for Israel, that constituted a rational decision. Since Republican members of Congress don’t have to mollify pro-Palestinian voters, they’re AIPAC’s most dependable allies. And if many of those Republicans used specious claims of Black voter fraud to oppose the democratic transfer of power in 2020 — and may do so again — that’s a price AIPAC seems to be prepared to pay.

F or the many American Jews who still consider themselves both progressives and Zionists, this growing alliance between leading Zionist institutions and a Trumpist Republican Party is uncomfortable. But in the short term, they have an answer: politicians like President Biden, whose views about both Israel and American democracy roughly reflect their own. In his speech last week, Mr. Schumer called these liberal Zionists American Jewry’s “silent majority.”

For the moment he may be right. In the years to come, however, as generational currents pull the Democratic Party in a more pro-Palestinian direction and push America’s pro-Israel establishment to the right, liberal Zionists will likely find it harder to reconcile their two faiths. Young American Jews offer a glimpse into that future, in which a sizable wing of American Jewry decides that to hold fast to its progressive principles it must jettison Zionism and embrace equal citizenship in Israel and Palestine, as well as in the United States.

For an American Jewish establishment that equates anti-Zionism with antisemitism, these anti-Zionist Jews are inconvenient. Sometimes, pro-Israel Jewish organizations pretend they don’t exist. In November, after Columbia suspended two anti-Zionist campus groups, the A.D.L. thanked university leaders for acting “to protect Jewish students” — even though one of the suspended groups was Jewish Voice for Peace. At other times, pro-Israel leaders describe anti-Zionist Jews as a negligible fringe. If American Jews are divided over the war in Gaza, Andrés Spokoiny, the president and chief executive of the Jewish Funders Network, an organization for Jewish philanthropists, declared in December, “the split is 98 percent/2 percent.”

Among older American Jews, this assertion of a Zionist consensus contains some truth. But among younger American Jews, it’s false. In 2021, even before Israel’s current far-right government took power, the Jewish Electorate Institute found that 38 percent of American Jewish voters under the age of 40 viewed Israel as an apartheid state, compared with 47 percent who said it’s not. In November, it revealed that 49 percent of American Jewish voters ages 18 to 35 opposed Mr. Biden’s request for additional military aid to Israel. On many campuses, Jewish students are at the forefront of protests for a cease-fire and divestment from Israel. They don’t speak for all — and maybe not even most — of their Jewish peers. But they represent far more than 2 percent.

These progressive Jews are, as the U.S. editor of The London Review of Books, Adam Shatz, noted to me, a double minority. Their anti-Zionism makes them a minority among American Jews, while their Jewishness makes them a minority in the Palestine solidarity movement. Fifteen years ago, when the liberal Zionist group J Street was intent on being the “ blocking back ” for President Barack Obama’s push for a two-state solution, some liberal Jews imagined themselves leading the push to end Israel’s occupation of the West Bank and the Gaza Strip. Today, the prospect of partition has diminished, and Palestinians increasingly set the terms of activist criticism of Israel. That discourse, which is peppered with terms like “apartheid” and “decolonization," is generally hostile to a Jewish state within any borders.

There’s nothing antisemitic about envisioning a future in which Palestinians and Jews coexist on the basis of legal equality rather than Jewish supremacy. But in pro-Palestine activist circles in the United States, coexistence has receded as a theme. In 1999, Mr. Said argued for “a binational Israeli-Palestinian state” that offered “self-determination for both peoples.” In his 2007 book, “One Country,” Ali Abunimah, a co-founder of The Electronic Intifada, an influential source of pro-Palestine news and opinion, imagined one state whose name reflected the identities of both major communities that inhabit it. The terms “‘Israel’ and ‘Palestine’ are dear to those who use them and they should not be abandoned,” he argued. “The country could be called Yisrael-Falastin in Hebrew and Filastin-Isra’il in Arabic.”

In recent years, however, as Israel has moved to the right, pro-Palestinian discourse in the United States has hardened. The phrase “From the river to the sea, Palestine will be free,” which dates from the 1960s but has gained new prominence since Oct. 7, does not acknowledge Palestine and Israel’s binational character. To many American Jews, in fact, the phrase suggests a Palestine free of Jews. It sounds expulsionist, if not genocidal. It’s an ironic charge, given that it is Israel that today controls the land between the river and the sea, whose leaders openly advocate the mass exodus of Palestinians and that the International Court of Justice says could plausibly be committing genocide in Gaza.

Palestinian scholars like Maha Nassar and Ahmad Khalidi argue that “From the river to the sea, Palestine will be free” does not imply the subjugation of Jews. It instead reflects the longstanding Palestinian belief that Palestine should have become an independent country when released from European colonial control, a vision that does not preclude Jews from living freely alongside their Muslim and Christian neighbors. The Jewish groups closest to the Palestine solidarity movement agree: Jewish Voice for Peace’s Los Angeles chapter has argued that the slogan is no more anti-Jewish than the phrase “Black lives matter” is anti-white. And if the Palestine solidarity movement in the United States calls for the genocide of Jews, it’s hard to explain why so many Jews have joined its ranks. Rabbi Alissa Wise, an organizer of Rabbis for Cease-Fire, estimates that other than Palestinians, no other group has been as prominent in the protests against the war as Jews.

Still, imagining a “free Palestine” from the river to the sea requires imagining that Israeli Jews will become Palestinians, which erases their collective identity. That’s a departure from the more inclusive vision that Mr. Said and Mr. Abunimah outlined years ago. It’s harder for Palestinian activists to offer that more inclusive vision when they are watching Israel bomb and starve Gaza. But the rise of Hamas makes it even more essential.

Jews who identify with the Palestinian struggle may find it difficult to offer this critique. Many have defected from the Zionist milieu in which they were raised. Having made that painful transition, which can rupture relations with friends and family, they may be disinclined to question their new ideological home. It’s frightening to risk alienating one community when you’ve already alienated another. Questioning the Palestine solidarity movement also violates the notion, prevalent in some quarters of the American left, that members of an oppressor group should not second-guess representatives of the oppressed.

But these identity hierarchies suppress critical thought. Palestinians aren’t a monolith, and progressive Jews aren’t merely allies. They are members of a small and long-persecuted people who have not only the right but also the obligation to care about Jews in Israel, and to push the Palestine solidarity movement to more explicitly include them in its vision of liberation, in the spirit of the Freedom Charter adopted during apartheid by the African National Congress and its allies, which declared in its second sentence that “South Africa belongs to all who live in it, Black and white.”

For many American Jews, it is painful to watch their children’s or grandchildren’s generation question Zionism. It is infuriating to watch students at liberal institutions with which they once felt aligned treat Zionism as a racist creed. It is tempting to attribute all this to antisemitism, even if that requires defining many young American Jews as antisemites themselves.

But the American Jews who insist that Zionism and liberalism remain compatible should ask themselves why Israel now attracts the fervent support of Representative Stefanik but repels the African Methodist Episcopal Church and the United Automobile Workers. Why it enjoys the admiration of Elon Musk and Viktor Orban but is labeled a perpetrator of apartheid by Human Rights Watch and likened to the Jim Crow South by Ta-Nehisi Coates. Why it is more likely to retain unconditional American support if Mr. Trump succeeds in turning the United States into a white Christian supremacist state than if he fails.

For many decades, American Jews have built our political identity on a contradiction: Pursue equal citizenship here; defend group supremacy there. Now here and there are converging. In the years to come, we will have to choose.
