Species are disappearing from the earth at a rate of hundreds, and perhaps thousands, of times greater than every before witnessed. According to many scientists, this rapid destruction will lead to irreversible changes in the earth's ecosystem. The Expendable Future provides a comprehensive and critical evaluation of the politics of biological diversity in the United States and of state and federal policies on endangered species from the early 1960s to the present. Drawing on congressional hearing and debates, previously unpublished public opinion surveys, interviews with state officials and employees of the Department of the Interior, and internal documents from this and other government agencies, Tobin provides an in-depth analysis of the policies on endangered species and the policy relationships among the different units of government involved in implementation. He examines the resources that are available for the protection of endangered species and the way in which those resources are matched to the priorities. Tobin also discusses the processes by which species are classified as endangered, how these species' critical habitats are determined and protected, and the successes, and mostly failures, of current recovery programs.
From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
This important book for scientists and nonscientists alike calls attention to a most urgent global problem: the rapidly accelerating loss of plant and animal species to increasing human population pressure and the demands of economic development. Based on a major conference sponsored by the National Academy of Sciences and the Smithsonian Institution, Biodiversity creates a systematic framework for analyzing the problem and searching for possible solutions.
