is an expansive, wide-ranging collection that addresses the pivotal environmental issues of the modern era. This eclectic volume on the varied constructions of “wilderness” reveals the recent controversies that surround those conceptions, and the gulf between those who argue for wilderness "preservation" and those who argue for "wise use." J. Baird Callicott and Michael P. Nelson have selected thirty-nine essays that provide historical context, range broadly across the issues, and set forth the positions of the debate. Beginning with such well-known authors as Ralph Waldo Emerson, Henry David Thoreau, John Muir, and Aldo Leopold, the collection moves forward to the contemporary debate and presents seminal works by a number of the most distinguished scholars in environmental history and environmental philosophy. also includes essays by conservation biologists, cultural geographers, environmental activists, and contemporary writers on the environment.
