The collapse of modern techno-industrial civilization is inevitable. William Rees, human ecologist and ecological economist, argues that humanity's nature evolved in simpler times and has left us wholly incapable of understanding the enormously complex and life-destroying global civilization we've created. The worldview of human exceptionalism, fueled by fossil energy and sustained by the myth of limitless growth and human ingenuity, is driving us deeper into ecological overshoot and leading humanity toward a painful contraction in both human population and consumption.
