Book excerpt: Environmentalism has relentlessly warned about the dire consequences of abusing and exploiting the planet's natural resources, imagining future wastelands of ecological depletion and social chaos. But it has also generated rich new ideas about how humans might live better with nature. Green Utopias explores these ideas of environmental hope in the post-war period, from the environmental crisis to the end of nature. Using a broad definition of Utopia as it exists in Western policy, theory and literature, Lisa Garforth explains how its developing entanglement with popular culture and mainstream politics has shaped successive green future visions and initiatives. In the face of apocalyptic, despairing or indifferent responses to contemporary ecological dilemmas, utopias and the utopian method seem more necessary than ever. This distinctive reading of green political thought and culture will appeal across the social sciences and humanities to all interested in why green utopias continue to matter in the cultivation of ecological values and the emergence of new forms of human and non-human well-being.
