Water is one of the most important resources on the planet. Without water, life cannot exist. But what makes water so important? Water has several unique characteristics that make it an extremely valuable resource. Some such properties of water are listed below.
- Water is a very good solvent – it has the ability to dissolve many substances.
- The boiling point and freezing point of water make it easily available in all three states (solid, liquid, and gaseous).
- The specific heat of water is quite high. This enables water to absorb and release heat slowly, thereby regulating the temperature of its environment.
- Owing to its transparency, water can allow light to reach the life forms that are submerged in it. This is crucial for the survival of plant life in the oceans, lakes, and rivers.
- Water is neither acidic nor basic in nature. It has a pH of 7, making it a neutral substance.
These unique qualities of water, along with its abundance on the planet (approximately 71% of the Earth’s surface is made up of water), make it a crucial resource for plants, animals, and human beings.

Importance of Water in Living Organisms

-
- Water is the medium through which all essential vitamins and minerals are transported in the bodies of living organisms (owing to its ability to dissolve a wide range of substances).
- Water also plays a vital role in facilitating the work of enzymes in living organisms. For example, the sodium bicarbonate secreted by the pancreas is broken down into ions by water, making the medium sufficiently alkaline for the enzymes to work.
- Water helps maintain body temperatures in plants and animals. In order to decrease the temperature in their bodies, animals lose water via perspiration (sweating) and plants lose water via transpiration.
- Since water can rise in capillary tubes without any external help, it can be transported from the roots of trees to every other part of the tree.
- Water is an integral part of photosynthesis. Without it, autotrophic plants would not be able to produce their own food.
- Water serves as a habitat for more than 50% of all life on Earth.

Importance of Water in Human Beings
-
-
-
- Insufficient water content in the human body results in severe dehydration, which is often accompanied by kidney failure, seizures, and swelling in the brain.
- Water helps improve the circulation of oxygen throughout the body.
- It also plays a crucial role in the digestion of food.
- Water is a very important component of saliva, which helps break down food.
- The excretion of waste in the human body requires water. Insufficient water levels in the body may increase the strain on the kidneys, resulting in the formation of kidney stones.

Other Important Uses of Water
-
-
-
- If not for the high specific heat of water, the temperature of the Earth’s surface would be much lower. This would make it difficult for life to survive.
- The water in the Earth’s oceans absorbs heat from the sun during the day and helps maintain the temperature during the night.
- Water is necessary for the irrigation of crops and is, therefore, an integral part of agriculture.
- It is widely used in cooking activities since it boils at a temperature of 100o
- Humans make use of water for a wide range of domestic activities such as washing and cleaning.
- Water also serves as a medium for the transportation of cargo. Many goods are transported between the Earth’s continents via ships.

Industrial Uses of Water
-
-
-
- Many industries require large quantities of water for processing, cooling, and diluting products. Examples of industries that consume large quantities of water include the paper industry, the food industry, and the chemical industry.
- Water is also used as an industrial solvent for the production of several commercially important products. Almost all power plants that generate electricity employ water to spin turbines.
- Heavy water, an important form of water, is widely used in nuclear reactors as a neutron moderator.

Frequently Asked Questions – FAQs
Why is water important?
In our body, water brings nutrients to all the cells and oxygen to our brain. Water enables nutrients, proteins, amino acids, glucose and other compounds to be consumed and assimilated by the body. Toxins and waste are washed out by sewage. In order to control body temperature, water helps.
What are the uses of water in our daily life?
To start, we all use water to drink, wash, clean, prepare, and grow food, making it our most precious survival resource. What contributes to the daily use of domestic water is that industry needs much more water to produce electricity, create materials, and move people and goods.
What is the importance of water supply?
Providing potable water is probably the most important of all public utilities. For drinking, heating, cleaning, carrying away waste, and other domestic needs, people rely on water. Water delivery schemes must also satisfy public, commercial and industrial specifications.

Why is water important to life essay?
The cornerstone of our lives is water. The human body needs water for everyday life. We can live without any food for a week, but we can not even survive without water for three days. 70 per cent of our body fluids are also water.
