New Haven, CT: Yale University Press, 1991.http://hdl.handle.net/10217/37180Environmental ethics stands on a frontier, as radically theoretical as it is applied. Alone, it asks whether there can be nonhuman objects of duty. Animals, plants, endangered species, ecosystems, and even Earth are progressively unfamiliar as objects of duty, and puzzles arise both for theory and practice. Answers to such questions are as urgent as any humans face, and intimately related to the four principal issues on the world agenda: peace, population, development, and environment.born digitalchapters (layout features)eng©1991 Yale University Press.Copyright and other restrictions may apply.
