Capitalism is destroying our planet, but like most social progress in the last two centuries, ecological justice can only be achieved through working-class struggle. In  Workers of the Earth , Stefania Barca uncovers the environmental history and political ecology of labour to shed new light on the potentiality of workers as ecological subjects. Taking an ecofeminist approach, this ground-breaking book makes a unique contribution to the emerging field of environmental labour studies, expanding the category of labour to include waged and unwaged, industrial and meta-industrial workers. Going beyond conventional categories of ‘production’ and ‘reproduction’ as separate spheres of human experience, Barca offers a fresh perspective on the place of labour in today’s global climate struggle, reminding us that the fight against climate change is a fight against capitalism.
