"… any plan to mitigate the effects of human overshoot like climate change, species extinction, pollution, or resource scarcity, with population reduction policies, or a steady-state economy using a full-reserve asset-backed monetary system, or voluntary degrowth, or balanced budgets, will cause a reduction of complexity, and therefore the population and its lifestyle that depends on growing complexity for resources will collapse, possibly quite quickly due to the many self-reinforcing feedback loops in supply chains, and the extreme level of current human complexity and overshoot."
