I think your premise is flawed or maybe your reference frame is extremely narrow.

As a whole, there’s basically never been a better time to be a human. There are fewer conflicts, higher standards of living, amazing medicine, etc. Yes, access to those things and damage to the environment are backsliding, but this is temporary. (Well, everything is temporary to a human if you want to go that route, but that’s not what I mean here). The trend line continues to go up, at least for now. The best thing that we can do is try to keep that trendline going up.

Yes, I am angry, I am disappointed, I am heartbroken, I am frustrated, and I am just generally sad at the current wars, erosion of rights, and environmental issues. However, I vote for what I believe in and try to advocate for it where I can. I try to avoid getting trapped in social media bubbles and spend very little time on it (and mostly only here when I do; no facebook or anything here). I try to go outside and raise plants. I am buying a farm where I can grow food, plant more native species, and do a tiny bit to heal at least the land under my feet whilst reducing my carbon footprint. I try to volunteer where I can. I have hobbies that take my mind away from these issues.

I can’t control other people. I can fight to convince them of something, but ultimately I cannot control them. Maybe the selfishness and contrarianism of some will destroy us all. If so, then I just know I did what I reasonably could to avoid it.
