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. InWorkers 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.
