The first study to link America's nature writing tradition to the development of its environmental organizations. ""Conserving Words"" looks at five authors of seminal works of nature writing who also founded or revitalized important environmental organizations: Theodore Roosevelt and the Boone and Crockett Club, Mabel Osgood Wright and the National Audubon Society, John Muir and the Sierra Club, Aldo Leopold and the Wilderness Society, and Edward Abbey and Earth First! These writers used powerfully evocative and galvanizing metaphors for nature, metaphors that Daniel J. Philippon calls ""conserving"" words: frontier (Roosevelt), garden (Wright), park (Muir), wilderness (Leopold), and utopia (Abbey). Integrating literature, history, biography, and philosophy, this ambitious study explores how ""conserving"" words enabled narratives to convey environmental values as they explained how human beings should interact with the nonhuman world.
