Importance of Water

Spread the love

There is a proverb in Hindi, “जल ही जीवन है”. It means ‘No Life Without Water’. Water is the source of all life. We can say that water is the basic necessity of all life form. Water is a transparent, tasteless, odorless, and nearly colorless chemical substance that is essential for the survival of living beings. About 71% of the Earth’s surface is water-covered, and the oceans hold about 96.5% of all Earth’s water. About 2.5% of the Earth’s water is freshwater; out of 2.5%, around 69% of the freshwater (69% of 2.5 %= 1.72%) is in form of ice cap and glacier and only 31% of the freshwater is available for drinking, this means 31% of 2.5% = 0.78% only. Yes, this calculation shocked me also. Water is more precious than Gold, Silver, Diamond, Platinum, etc.

Oceans water is salty and cannot be used for irrigation or any other agricultural use. It is not even good for industrial or domestic use. So this is very important to use water wisely. This point is emphasized time and again. However, its criticality is not yet recognized by the people. It is essential to understand the importance of saving water else we will have to learn it the hard way.

Many countries around the world are facing a water deficit problem, especially in developing countries. India is one of them. New elected Government of India (2019-2024) formed a new ministry called “The Jal Shakti Ministry” on May 31, 2019, by reorganizing erstwhile ministries of Water Resources, River Development & Ganga Rejuvenation and Drinking Water & Sanitation.

What is the Water Cycle?

The water cycle is a continuous movement of water within the Earth and atmosphere. It’s always changing on earth. Its repeating changes make a cycle. Water can be a solid form (ice) or a liquid form (water), or a gas form (water vapor). Ice can change to become water or water vapor. Water can change to become ice or water vapor. Water vapor can change to become ice or water. This entire procedure called Water Cycle.

If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapor. If heat is taken away from water vapor, it condenses. Condensation turns water vapor into a liquid. If heat is taken away from liquid water, it freezes to become ice.

The water cycle is called the hydrologic cycle also. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation. Precipitation is either absorbed into the ground or runs off into rivers. Water that was absorbed into the ground is taken up by plants. Plants lose water from their surfaces as vapor back into the atmosphere. Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere. The cycle continues……. 

Sources of Water

The sources of water are mainly divided into two categories – Surface Water and Ground Water. Rainwater pours and collects on earth in the form of surface water as well as groundwater. Here is a brief look at both these sources of water:

Surface Water: Surface Water found in rivers, lakes, reservoirs, streams, seas and other such sources. The water in lakes and rivers comes from rain and the melting of snow. The river water flows into the sea.

Ground Water: Ground Water found under the ground. Water travels under the surface of the land by way of soil on the non-porous rocks and fills the opening in these rocks. The rocks that store and send out groundwater are known as aquifers. At times, the water stored in these rocks bursts in the form of springs due to high pressure. Groundwater is also extracted by digging wells and tube wells.

Uses of Water

Water is an essential thing for every living being. We even cannot think to live without water. On a daily routine, we are using water. Here are some uses of water.

Drinking

Water that is used for drinking is called potable water. In our body, 70 percent of water is there. Our body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because our body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking fluids and eating foods that contain water.

Cooking

Can you prepare your food without water? Can you imagine that if you don’t have water in your kitchen and you are hungry then what can you cook without water? Everything requires some amount of water in food preparation. Water not only boils and therefore kills all the germs in your food making it healthy, but it also is an important part of the dish to make it yummy.

Irrigation

Water is used for irrigation also. Water is needed for all kind of crops. Crops need water, sunlight, and nutrition from the soil to grow. Every year farmers sow seeds and wait for rains to replenish their farms to get their crops ready for the harvest season.

Washing and cleaning

Whether it is your clothes, your house or your body, we need water for cleaning and washing. Because of certain properties of water, it makes an excellent agent for cleaning and washing. Water also cleanses and breaks down waste that humans so abundantly make. 

Provides Home to Millions of Creatures

Almost 2/3 part of the earth is covered with water so these oceans, rivers, and ponds are home to more life than on land. Millions of creatures like Mammals, fish, birds, insects, trees, plants, algae, krill, and many other forms of life either live directly in water or are wholly dependent upon it for survival.

These are the main uses of water. Water is used for traveling & for transport also. There are some water games also. So water is the most important thing in our life.

So we can say that without water, no life because we all need water. Water regulates the earth’s temperature also. It is time for us to control the use of water, stop doing waste of water and trying to conserve this valuable resource otherwise our new generation will suffer.
