Fresh Water - Water Distribution

Water Distribution

Water is a critical issue for the survival of all living organisms. Some can use salt water but many organisms including the great majority of higher plants and most mammals must have access to fresh water to live. Some terrestrial mammals, especially desert rodents appear to survive without drinking but they do generate water through the metabolism of cereal seeds and they also have mechanisms to conserve water to the maximum degree.

Out of all the water on Earth, salt water in oceans, seas and saline groundwater make up about 97% of it. Only 2.5-2.75% is fresh water, including 1.75-2% frozen in glaciers, ice and snow, 0.7-0.8% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers. Freshwater lakes contain about 87% of this fresh surface water, including 29% in the African Great Lakes, 23% in Lake Baikal in Russia, 21% in the North American Great Lakes, and 14% in other lakes. Swamps have most of the balance with only a small amount in rivers, most notably the Amazon River. The atmosphere contains 0.04% water. In areas with no fresh water on the ground surface, fresh water derived from precipitation may, because of its lower density, overlie saline ground water in lenses or layers. Most of the world's fresh water is frozen in ice sheets. Many areas suffer from lack of distribution of fresh water, such as deserts.

Famous quotes containing the words distribution and/or water:

    Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.
    Cyril Connolly (1903–1974)

    It may be that through habit these do best,
    Coming to water clumsily undressed
    Yearly; teaching their children by a sort
    Of clowning; helping the old, too, as they ought.
    Philip Larkin (1922–1986)
