Book excerpt: Economics of Natural Resources and the Environment brings together the approaches of natural resource economics and environmental economics to provide a comprhensive overview of the economics of national international and global environmental problems. A unifying theme throuhhout the book is the concept of "sustainable development" defined as "maximizing the net benefits of economic development while maintaining the services and quality of natural resources over time." The authors emphasize the continuing importance of a mainstream approach. They stress "economic efficiency—getting the most welfare out of a given endowment of resources." And they address the larger moral issues as well. Chapter topics include the historical development of environmental economics, environmental ethics, and pollution control policy in "free" mixed market and centrally planned economies. Other current issues seen from an economic perspective include destruction of the ozone layer, the greenhouse effect, policy weapons in the fight against pollution, and the special problems of the third world. Economics of Natural Resources and the Environment offers a thorough review and synthesis of the major work of the field's senior scholars. It will be of value not only to students of natural resource economics, environmental economics, geography, and environmental sciences but also to all with an interest in economic appraoches to environmental issues.
