After Earth Day celebrates the spirit of Earth Day as exemplifying the sustained commitments of many different people and organizations to a common cultural effort:conservation itself. As the essays show, conservation depends upon the continuing efforts of everyone: people in business, in the university, in science and technology, and citizens in every community who act locally but think globally. Essays cover conservation politics, environmental science, economics and the corporation, environmental philosophy and religion written by some of North America's leading environmental thinkers: Susan Bratton, Elinor Gadon, Pete A. Y. Gunter, Eugene Hargrove, Dolores LaChapelle, Max Oelschlaeger, Robert Paehlke, George Sessions
