In childhood we read in our geography books that three fourth of our earth consists of water bodies. We live on the one fourth that is left. Though there is so much water out there we can barely use 1% of it for drinking, bathing, cultivation and industrial work. This is because the amount of fresh water compared to the total amount of water on earth is negligible. Most of the water bodies consist of saline water which we cannot drink or use for different daily purposes. Most of us have been blessed to have water at our beck and call but there are millions of people for whom fresh and clean drinking or bathing water is a privilege.
