About 71% of the earth’s surface is covered with water and even then we face scarcity of water.
Reasons:
1. 97% of total water is found in seas and oceans, which is salty and not fit for human consumption.
2. Only 3% found is the freshwater and that too available in polar ice caps and glaciers.
3. Out of 3% fresh water, only 0.3% is available to us as surface water, in lakes, rivers, and swamps.
