When I get that angst I look at age demographics charts for my country. Much of current days politics are from old people who want nothing to progress and would prefer to go back a century or two. But the younger generations are strongly opposed to that and of course own the future. 20 is far too young to step back and depoliticize yourself. Use that shock for progress where you can make it. And do set out on a career in whatever pays and you like.

Maybe interact with some older people and be friendly while being as out of their comfort zone as you want. It bridges gaps.

Edit-also, I know many viewpoints say what’s already happened is baked in and it’s impossible to clean up the situation. This is fundamentally opposed to human nature and power of human will. Yes there are large problems, but it’s precisely existential crises that bring out the strongest response from an organism and, collectively, our humanity. If we want carbon out of the air bad enough there will be a technological way to do it. Many other such things. Plus this period might cure humanity of its apathy towards the commons-if humanity is scared, harmed, and pissed off enough to force it.
