This is often labelled the most subversive economics book of the decade. Capitalism will not lead us out of the crisis. Any economic recipe based on continuous growth leads to the destruction of the planet. The only option is to put on the brakes. And Marx has something to teach us in this regard. The political-economic manifesto that all left-wingers around the world must confront. In a period of eco-anxiety, in which increasingly extreme weather forces us to come to terms with the habitability of certain parts of the globe and the sustainability of our way of life, Saito bursts into the debate with courageous, radical and thoughtful proposals. Techno-utopianism, the Green New Deal and the superficial environmentalism of companies are not the solution. And small daily gestures by individuals are not enough. If we do not accept the idea that resources are limited and address the problem of inequality, we are doomed. We must return to the essentials, to concrete things, to community. In short, we must rediscover what Marx called “the metabolic relationship between man and nature”. n short, we must rediscover what Marx called “the metabolic relationship between man and nature”.
