Summary:
Though water is essential to survival, most take this precious resource for granted. In fact, only 1 percent of the water on this planet is available for human needs. This award-winning program explains the hydrologic cycle, as well as the many ways that water is used, wasted and polluted by industry, agriculture, power plants, landfills, industrial chemicals and oil spills in the ocean. The Earth at Risk Scholars perform tests on upstream and downstream runoff, while an interview with an ecologist from a wastewater processing plant shows how organic material can be used to treat and clean sewage. Some solutions discussed include water conservation, working for new legislation to protect water sources and educating people about water pollution. Part of The Earth at Risk Environmental Video Series that examines the threats facing Earth and the environment.

Only available in the US.
