The continuous rise in the profile of the environment in politics reflects growing concern that we may be facing a large-scale ecological crisis. The new edition of this highly acclaimed textbook surveys the politics of the environment, providing a comprehensive and comparative introduction to its three components: ideas, activism and policy. Part I explores environmental philosophy and green political thought; Part II considers parties and environmental movements; and Part III analyses policy-making and environmental issues at international, national and local levels. This second edition has been thoroughly updated with new and revised discussions of many topics including the ecological state, ecological citizenship, ecological modernisation and the Greens in government and also includes an additional chapter on 'Globalisation, Trade and the Environment'. As well as considering a wide variety of examples from around the world, this textbook features a glossary, guides to further study, chapter summaries and critical questions throughout.
