Book excerpt: This volume of original essays tells the story of how the agenda of the environmental movement in America has changed from the time Rachel Carson sounded her famous clarion call in the early 1960s up to our current era when the &"globalization&" of environmental issues has affected both the severity of the problems we all face and the political difficulty of dealing with them. Besides the editor, whose Introduction and Epilogue frame the book, the contributors include well-known journalist Roy Beck, activist/civil servant Leon Kolankiewicz, environmental scholar Michael E. Kraft, historian Martin V. Melosi, and political scientist David Vogel.This volume was originally published as a special issue of The Journal of Policy History.
