We are massively more resilient than cockroaches, everything we've thrown at us we've survived. 50,000 years ago it is hypothesized that due to catastrophies we can't even possibly begin to emulate, like supervolcanoes and ice ages, the entire human population was reduced to around 10,000 breeding individuals. Yet 50,000 years later here we are.

The only upside is that if things get bad enough, the survivors won't be able to achieve our excesses again because we've already exhausted all the irreplaceable easily accessible deposits of fossil fuels and minerals.
