The promise of wilderness is a wonderfully written, well documented and pleasant book. It is also very innovative in the way it analyses American environmental politics throughout the second half of the century. It gives a whole new explanation about the evolution of American politics, starting with the wilderness movement (the Wilderness Act of 1964) to the emergence of today's environmental concerns boosted by advanced scientific techniques. James Morton Turner takes the reader on this journey through the scope of the two mainstream environmental groups: The Sierra Club and the Wilderness Society and the four federal agencies overseeing our lands: The National Park Service, the Forest Service, the Fish and Wildlife Service and the Bureau of Land Management. Throughout the journey, you will learn the political forces that have shaped those entities, the charismatic figures who led the way in crucial legislative battles. The level of details in this book is stunning and the quality of Turner's research makes the Promise Of Wilderness a strong reference that will definitely have a strong impact on the way we see American environmental history. As an activist with the Sierra Club and a lover of our wild heritage, this book has found a precious place in my library.
