You can not even with full on genius level intelligence predict all the possible random course changes of the path we are headed down, the only predictable thing about the future is that no one will accurately predict it.

That’s one. Two - you can of course be concerned and inform yourself and inform others, but worrying or obsessing on a doomed future is pointless, you can’t change the big picture by yourself, and if it’s definitely doomed, you really can’t, so what’s the point in worrying about it? Instead of having an unhealthy relationship with it, do what you can to help the here and now, the people and animals and situations you can. If the world is going to have some unpredictable course change that means we actually turn this boat around or get off it successfully, the only way it’s gonna happen is if enough people refuse to succumb to panic and defeatism and continue to do the hard work, whatever that is for them. So do that.
