According to recent estimates 400,000 people die every year as a result of human-made global warming. The UN projects that 3 billion additional people may be pushed into extreme poverty by 2050 because of environmental destruction. The scale of the problems we face makes it clear that individualist, lifestyle-centric approaches to activism will not suffice. We need to change the structures of our social system, not our light bulbs. This book seeks to expose the structural roots of the injustices we must confront, and outlines an approach to activism which transcends the hopeless individualism of our time.
