Is environmentalism necessary? Is environmentalism good for society? What is the state of the environmental movement? These three questions are answered by a lively collection of pro versus con essays across three chapters. Viewpoints are intentionally contrary, so that more than one intelligent perspective is presented. This allows readers to analyze issues through critical reasoning skills. Essayists include Will Potter, Gregory Vickrey, Ruedigar Matthes, Edward L. Glaeser, and Lisa P. Jackson.
