Book excerpt: As a contribution to public policy and to help educate students about natural resource issues, this book identifies the likely "hot spots" of environmental policy and presents alternative and often opposing points of view on the major controversies that are likely to be with us well into the next century. Among the topics covered are comparative risk assessment; market incentives in environmental regulation; environmental justice; public versus private management of public lands; international trade and sustainable development; and the relationship between national security and environmental protection.
