Workers are not doomed to be merely the victims of environmental devastation. As Lorenzo Feltrin shows, they can be key actors in preventing it. Because labour supports an unsustainable system of endless growth, it holds a central place in any strategy for our long-term survival. Bringing Italian workerist theory into dialogue with a range of traditions from dependency theory to ecofeminism, Feltrin examines the intersection of labour and nature across the globe. By addressing several urgent dimensions of the ecological crisis, such as automation, precarious employment, imperialism and social reproduction, he offers a new framework for understanding how labour struggles and environmental justice are intertwined.
