Beschreibung
Among the various natural resources available on earth, Water is one of themost important natural resource. Without it, life cannot be imagined on earth. 71% of the total Earth's surface is covered with water, and is mandatory for all known forms of life. On earth, Oceans have the major share of the total water, i.e. 96.5%, 1.7% present in the form of groundwater, 1.7% in glaciers and the ice caps of Antarctica and Green land, a very small fraction in other large water bodies, and 0.001% in the air as vapor, clouds, and precipitation. The Freshwater percentage is only 2.5, and out of it 98.8% are in the form of ice and groundwater. So, less than 0.3% of allfreshwater is in rivers, lakes, and the atmosphere. Water is taken for granted because of abundance, but the problem with water is it is not always present in the proper place, at the proper time and of the proper quality.
