Environmental Ethics is a systematic account of values carried by the natural world, coupled with an inquiry into duties toward animals, plants, species, and ecosystems. A comprehensive philosophy of nature is illustrated by and integrated with numerous actual examples of ethical decisions made in encounters with fauna and flora, endangered species, and threatened ecosystems. The ethics developed is informed throughout by ecological science and evolutionary biology, with attention to the logic of moving from what is in nature to what ought to be.  The ethical theory is applied in detail to social, public, and business policy. Written in an engaging style, using diagrams and figures as well as numerous case studies, Environmental Ethics prods the reader into concrete application and invites reader participation in the ethical discussions. The ethics concludes by exploring the historical experiences of personal residence in a surrounding environment. Here is an adventure into what it means to live as responsible human beings in the community of life on Earth.
