Environmental issues are of fundamental importance, and a broad approach to understanding the relationship between the human economy and the natural world is essential. In a rapidly changing policy and scientific context, this new edition of Environmental and Natural Resource Economics continues to reflect an updated perspective on modern environmental topics. Now in its sixth edition, this textbook includes enhanced and updated material on energy, climate change, population, agriculture, forests, and water, reflecting the greater urgency required to solve global, regional, and local environmental problems in these areas. It introduces students to both standard environmental economics and the broader perspective of ecological economics, balancing analytical techniques of environmental economics with a global perspective on current ecological issues such as global climate change, ocean degradation, plastic pollution, water shortages, and other environmental challenges.
