About 70% of our body weight is composed of water. Water is essential for all the biological functions and hence is essential for supporting life. Although about two-thirds of the earth’s surface is covered with water, most of it is present in ocean in the form of saline water. Less than 1% of total water on the earth is available for our use. This shows that water is a valuable resource and hence we should take every effort to conserve water. Save water, because water is precious.
