People need to water to live as much as they would need air.
Animals and plants too need water. If there was no water, we would all die.

Rain, ground wells, tube wells, waterfalls, tanks, ponds, rivers and streams,
are some of the sources of water. We drink water and use water for cooking, washing
 cloths, generating electricity, washing our selves and for cultivation. 
 There is water in the sea, but we cannot drink it or use it because it is salty.
 People pollute the sources of water through their indiscriminate actions.

 We need water conservation because water is our life.
