This urgent book brings our cities to the fore in understanding the human input into climate change. The demands we are making on nature by living in cities has reached a crisis point and unless we make significant changes to address it, the prognosis is terminal consumption. Providing a radical new argument that integrates global understandings of making nature and making cities, the authors move beyond current policies of mitigation and adaption and pose the challenge of urban stewardship to tackle the crisis. Their new way of thinking re-orients possibilities for environmental policy and calls for us to reinvent our cities as spaces for activism.
