Book excerpt: People organising to protect their environment is not a new phenomenon, but the groups that have been pushing for environmental change since the 1970s have not convinced sufficient numbers make sustainable decisions or to lead sustainable lives. Governments have serially failed to do the job at the international level. Now, climate change, resource depletion and widening social aspirations threaten to destabilise human society unless sustainable change can be influenced from another direction. The Coming of Age of the Green Community explores the activities of a new generation of community-led initiatives that may herald the beginnings of the next wave of activism. Erik Bichard combines the testimonies of dozens of group activists with historic evidence and the views of a range of commentators from a variety of disciplines to put forward reasons why some green community groups succeed while others fail. He concludes with a valuable prescription for both existing and emerging groups on how to be sustainable, both over time and in their actions. This book address one of the key questions of the twenty-first century: has the local perspective on this universal concern finally come of age?
