Revised edition of the classic text. Examining traditional attitudes towards nature, and the degree to which these attitudes enable us to cope with modern ecological problems, the author looks particularly at the Judeo-Christian heritage of belief in man's dominion, the tradition of stewardship, and the more recent belief in progress to determine the extent to which these attitudes underlie ecological problems and how far they embody resources adequate for combating such problems. Concerns of applied ethics are also considered, in particular in relation to the treatment of other animals, pollution, scarce natural resources, population growth, and the conservation and preservation of the environment.
