Water is an essential for mankind to survive. At first, the global water crisis may seem rather insignificant. Over 71% of the earth’s surface is covered by seas, oceans, and other water bodies. But when we stop to consider that less than 2.5% of this water is freshwater, we may start to see why water is a precious commodity. Of this freshwater, over 70% forms the ice and snow cover of mountains – the origin of most rivers. 29% of the freshwater is underground and a less than 1% is easily accessible for our daily consumption.
