This book provides the most detailed and comprehensive examination to date of the impact of environmentalism upon contemporary political thought. It sets out to disentangle the various strands of Green political thought and explain their relationship to the major Western political traditions. Environmentalism and Political Theory represents the consolidation of a new field of political inquiry that is destined to become an increasingly important component of political studies and political reporting worldwide. An interdisciplinary study that builds bridges between environmental philosophy, ecological thought, and political inquiry, this book employs a range of new insights from environmental philosophy to outline a particular Green political perspective.
