Abstract: The relationship between people and the rest of nature is central to the debate concerning the management of natural resources. An understanding of how environmental concern is reflected in people's attittudes and value systems is important for the development of responsive environmental management. Effective attitude measures already exist, most notably the New Environmental Paradigm scale. Since this measure was produced, however, certain issues not addressed by the scale have become increasingly important within the environmental debate. These include concepts such as the intrinsic value of nature, or the moral duties of humans to the rest of nature-issues that surface repeatedly in the environmental literature. The study has shown that it is possible to include references to the intrinsic value of nature, as well as the moral duties people have to the rest of nature and to other human beings, within a reliable and unidimensional attitude scale.
