I was reading about environmental movements, in particular the ones often considered more extreme. One of the main tenets of one of the major "deep ecology" movements is the belief that industrial civilization will inevitably collapse. The Deep Green movement holds that current environmental and land use policies are totally unsustainable, one of the main reasons being that we extract far more energy than the land can sustainably provide, and also that we PRODUCE far more waste than the system can abosrb. Ergo, total social collapse is inevitable, as our ecological bank account is vastly overdrawn. What do you think?
