I'm sure we can survive fairly reasonably in whatever climate we end up with in a few hundred/thousand years, but the gap in between is a really doozy. The stories and myths about the selfish people of our times will go on for millennia.
It is the book series 'Carbon Ideologies' by William T Volleman, the opening few pages are written to those that read them in a few hundred years. Those that read these today are already convinced, those in the future will want answers. All he does is use examples of how we live to point out that we are not inherently evil, just looking out for our more immediate needs.
Except there is nothing inherently more selfish about ”people” today than at any point in history.
If anything, it might change humanity’s view of itself, and its capability to collectively handle major threats.
