What role can philosophers play in helping to resolve the moral and political dilemmas faced by environmental activists and policymakers? Moving away from environmental philosophy's usual focus on abstractions such as nonanthropocentrism and the intrinsic value of nature, this book focuses on environmental practice as the starting point for theoretical reflection. Philosophical thinking, it argues, need not be divided into the academic and the practical. Philosophy can take a more publicly engaged approach.The authors combine a deep understanding of the environmental ethics literature with a sympathetic sociological and political examination of environmental activists and their reasoning. The book is divided into three parts: Political Theory and Environmental Practice, Philosophical Tools for Environmental Practice, and Rethinking Philosophy through Environmental Practice. Case studies are included from Canada, Denmark, India, the United Kingdom, and the United States. Topics range from the specific, such as fox hunting and leaded gasoline, to the more general, such as biodiversity in India, biomedical ethics, and crop biotechnology.
