Through overpopulation and excessive consumption, humanity is depleting its natural resources, polluting its habitat, and causing the extinction of other species. Continuing like this will lead to the collapse of civilisation and likely our own extinction.
This one seems very common to me, and sadly people often feel fatalistic about it.
Two things that feeling might come from:
People rarely talking about aspects of it which are on a positive trajectory (e.g. the population of whales, acid rain, CFC emissions, UN population projections).
The sense that there are so related things to solve—such that even if we managed to fix (say) climate change then we’d still see (say) our fisheries cause the collapse of the ocean’s ecosystem.
