This anthology, edited by a professor of wild-life science and a professor of philosophy, offers the most current and comprehensive collection on the topic of environmental ethics available today. It surveys diverse approaches to environmental ethics by leading writers from a variety of disciplines, and provides an historical survey of thought on our responsibility to the environment. The perspectives are represented by their most articulate spokespersons and are accompanied by appraisals of their respective strengths and weaknesses. Chapter introductions, headnotes, discussion questions, and annotated bibliographies are provided. Twenty eight of the 64 articles are new. The new edition deletes those articles with which students had difficulty because they were hard to read and substitutes newer or better-written articles. All chapter introductions were revised to reflect changes in the field. New topics include biodiversity, ecological restoration, environmental justice, and genetic engineering. A new section in the appendix on conflict resolution was requested by students.
