Since the thermo-industrial revolution the human imprint on the Biosphere has become so important that some scientists speak of a new geological era, the 'Anthropocene.' The current financial, social and energy crises need tobe understood in this irreversible context, and require a new kind of economic thinking. Conventional theory and practice has failed to take account of the scale and significance of this unparalleled historical situation. This book examines the rich intellectual traditions of heterodox economics - particularly ecological and critical institutional economics - toprovide guidelines for an alternative paradigm for thisnew age. The authors develop key integrative concepts such as social metabolism, value pluralism, evolution and community, gathering together some of the world's foremost heterodox economists.
