The global community's ability to deal effectively with environmental problems is contingent on the successful integration of international relations theory with ecological thought. Yet, while most scholars and policymakers recognize the connection between these two interrelated branches of study, no substantial dialogue exists between them. This volume seeks to fill the lacuna with an original synthesis. By framing the environmental question within a historical and philosophical context, it highlights problems inherent in economistic and managerial approaches to sustainable development policy. Emphasizing environmental consciousness as a cultural norm in an evolving set of global relations, it tackles important debates on naturalism, foundationalism, and radical ecology.
