Each Drop Matters

Each drop of water is a source of life. Life would not have even begun if water had been absent on the surface of the earth. More than 70% of the earth’s crust is covered with water. Out of this, 97% of the water is in the form of saline water and 3% in the form of fresh water. Life survives in both saline water and fresh water. It is the fresh water that is potable by human beings and other living beings.

Water is a great resource without which life cannot be even imagined. Even 70% of our body is composed of water. Water has so many uses for life, be it for our daily use or others. We cannot survive without drinking water. Water is also needed to cook, to bathe, to clean and a million more uses in day to day work. Water is also important in the industries. Many chemical reactions don’t even take place without the presence of water. Water is necessary not only for human beings, but also other living beings. Plants cannot perform photosynthesis without the presence of water and animals cannot survive without drinking water.

Water is also a source of renewable energy. Water is used for the generation of electricity in hydel power plants. Nowadays, the difference in temperatures between the surface and sub-surface water is also being used as a source of energy. Tidal power is also being tapped.

The purest form of water available to us is in the form of rain, glaciers or fresh surface water. Water pollution makes water unfit for the uses listed above, thus in the long run curbing the sustenance of life itself. While the air pollution leads to Acid rain, polluting rain too.

Global warming is also adding to the existing problems. For instance, in the Pacific Ocean we have both warm currents and cold currents, which in turn give rise to warm winds and cool winds. Due to global warming, the temperature of both the currents is almost equalised which leads to the creation of only warm currents and consequently warm winds. Thus the monsoon winds are depleted of their water vapour even before they hit the surface, and hence the rains are lesser than normal. Having a year with low rainfall, means that it is a year of draught where the crops fail, and the public encounters problems of drinking water, as the levels of ground water drop.

As it is, the problem of population explosion makes it impossible to satisfy all the needs of water for everyone.

The only way for us out of this problem is to save water and control the emission of toxic materials from industries into both water and air. If not controlled, the emissions should at least be rid of toxic materials. We can also do our part as citizens to help conserve water. Instead of using a tub full of water or running a shower, we use a bucket to bathe. We could just turn the tap off while brushing and use it only when required. We could turn the taps off properly once we’ve done with them to prevent loss of water drop by drop. There is even a mechanism called half-flush in most of the commodes.

Awareness should also be brought about in the rural areas especially, where the local water body is used for every purpose, be it for washing farm animals or drinking. Planting more trees also helps to better rainfall. Each one should plant one; felled trees can also be relocated to barren areas of land, so that the balance is maintained.

By thoughtful and intelligent use of water we can save as much water as possible. Every element of nature is interlinked with the other. If one perishes, life itself will perish.
