A sense of urgency pervades global environmentalism, and the degrowth movement is bursting into the mainstream. As climate catastrophe looms closer, people are eager to learn what degrowth is about, and whether we can save the planet by changing how we live. This book is an introduction to the movement. As politicians and corporations obsess over growth objectives, the degrowth movement demands that we must slow down the economy by transforming our economies, our politics and our cultures to live within the Earth's limits. This book navigates the practice and strategies of the movement, looking at its strengths and weaknesses. Covering horizontal democracy, local economies and the reduction of work, it shows us why degrowth is a compelling and realistic project.
