[1] The recent resurgence of interest in "degrowth" economics—a movement advocating for the intentional reduction of global production and consumption—has sparked vigorous debate among ecological economists. [2] Advocates of degrowth contend that infinite economic expansion is biophysically impossible on a finite planet, and that curbing gross domestic product is the only reliable method to avert ecological collapse. [3] Critics, however, maintain that technological innovation and the decoupling of resource use from economic growth can allow for sustainable expansion without sacrificing living standards. [4] While both sides present compelling ecological data, the degrowth movement's proposed solutions ultimately fail because they severely underestimate the political and social instability that would inevitably result from a deliberately induced global economic contraction. [5] Implementing degrowth policies would require a massive redistribution of wealth and an unprecedented level of international cooperation, neither of which is politically feasible in the current geopolitical climate. [6] Furthermore, a forced reduction in economic output would disproportionately harm developing nations, which rely on sustained growth to lift their populations out of poverty and build essential infrastructure.
