This book undertakes the first general assessment of ecological economics from a Marxist point of view, and shows how Marxist political economy can make a substantial contribution to ecological economics. The analysis is developed in terms of four basic (1) nature and economic value; (2) the treatment of nature as capital; (3) the significance of the entropy law for economic systems; (4) the concept of sustainable development. In each case, it is shown that Marxism can help ecological economics fulfill its commitments to multi-disciplinarity, methodological pluralism, and historical openness. In this way, a foundation is constructed for a substantive dialogue between Marxists and ecological economists. Paul Burkett, Ph.D. (1984) in Economics, Syracuse University, is Professor of Economics at Indiana State University, Terre Haute. His publications on Marxism and ecology include Marx and A Red and Green Perspective (St. Martin's Press, 1999) and many articles in scholarly journals.
