摘要：Planets 71% surface area is covered by gigantic water bodies, which gives a very sound and satisfying scene but the astonishing and vulnerable fact which hampers human hearts is that only a meager portion is the share of fresh water i.e. 2.8% of the total water content available. This picture becomes profoundly deleterious in the light of Fact that out of the 2.8% potable water 2.14% lies in from of glaciers and ice sheets, leaving only a very small quantum (0.66%) of usable water that too is unevenly distributed.
