Abstract
During the last two or three decades, various developments in the environmental sphere have led to increasing concern with our obligations to posterity and to the non‐human part of the natural world. These developments have exposed gaps in both traditional, moral, and political theory and in conventional economics. Environmental issues have exposed these gaps and have brought to the fore questions such as how far the society, with whose welfare we are concerned, includes future generations or is limited to individual nations or human beings. This book examines these questions as well as related ethical aspects of environmental policy, such as environmental valuation or the equitable allocation among nations of the burden of environmental protection.
