In a Dark Wood presents a history of debates among ecologists over what constitutes good forestry, and a critique of the ecological reasoning behind contemporary strategies of preservation, including the Endangered Species Act. Chase argues that these strategies, in many instances adopted for political, rather than scientific reasons, fail to promote biological diversity and may actually harm more creatures than they help. At the same time, Chase offers examples of conservation strategies that work, but which are deemed politically incorrect and ignored. In a Dark Wood also provides the most thoughtful and complete account yet written of radical environmentalism. And it challenges the fundamental -- but largely unexamined -- assumptions of preservationism, such as those concerning whether there is a "balance of nature", whether all branches of ecology are really science, and whether ecosystems exist. In a Dark Wood will be of interest to environmentalists, ecologists, philosophers, biologists, and bio-ethicists, and anyone concerned about ecological issues. Yet it is also a smashing good read, judged by a recent national poll to be one of the 100 best nonfiction books written in the English language during the twentieth century. In his new introduction, Chase evaluates the response to his book and reports on recent developments in environmental science, policy and politics.
