Capitalism today is caught in a seemingly endless crisis, with economic stagnation and upheaval circling the globe. But while the world has been fixated on the economic problem, global environmental conditions have been rapidly worsening, confronting humanity with its ultimate crisis: one of long-term survival. The common source of both of these crises resides in the process of capital accumulation. Likewise the common solution is to be sought in a “revolutionary reconstitution of society at large,” going beyond the regime of capital.… It is still possible for humanity to avert what economist Robert Heilbroner once called “ecological Armageddon.” The means for the creation of a just and sustainable world currently exist, and are to be found lying hidden in the growing gap between what could be achieved with the resources already available to us, and what the prevailing social order allows us to accomplish. It is this latent potential for a quite different human metabolism with nature that offers the master-key to a workable ecological exit strategy.
