A plentiful supply of fresh water is essential to the survival not only of the human race, but also of most living things on Earth. Yet recent years have brought many examples of water stress, from falling water tables across the U.K., to catastrophic droughts across Southern Africa and in many of the world's most significant grain-producing regions. Where freshwater supplies are not threatened by shortages, analysis of their content often reveals disturbing levels of pollution, including non-degradable organophosphates which may have a significant impact on the health and reproductive capacity of living creatures. Two cases in point are the Rhine and the Great Lakes.

The Water Crisis examines the sources and effects of modern freshwater pollution, and presents existing ecological technology which may be implemented by business or by members of the public who would like to take responsibility for the water they use.
