This successful volume provides a broad, up-to-date survey of the major environmental issues facing the world today. Its dual approach is to describe the ecological impact of various human activities combined with specific issues of personal and community health, emphasizing the interrelatedness of the two. A great strength is its ability to impart to readers a sense of how these environmental issues directly affect their own lives, as well as too make them aware of opportunities to participate in the decision-making processes that will influence health and environmental quality in years to come. Beginning with a rudimentary discussion of general ecological principles, the book focuses primarily on our present population-resources- pollution crisis and explains why human health and welfare depend on a successful resolution of these challenges. The material is enhanced by 89 photographs and more than 85 maps, charts, and graphs.
