Green Alert: Polluted Waters

Product Description

Over a fifth of the world's population does not have access to safe drinking water. One of the main causes is human activities, from dumping and domestic sewage, to agricultural and industrial runoff. Polluted Waters takes an in-depth look at the sources of water pollution and the need to conserve our limited supply. Topical examples look at the effects on people, animals and plants, as well as the countries, organizations and individuals working to prevent further damage.
