In my view for humanity to exist long term we need to become a interplanetary species. An impact like the one that killed the dinosaurs can certainly happen again and the sun has a expiration date. Ultimately what is purposed isn't even a solution to the problem. Small reductions here and there that in total only manage to delay the inevitable. The only solution is mass scale terraforming projects and genetic modification of existing species to increase resiliency. If the coral reefs are dying we need to build reefs that are more resilient. If polar bears are overheating we need to breed ones who are more temperature tolerant. If the fish of the sea do not breed quickly enough for us to consume them at the rate that we currently do, we need to increase yields.
