I used to love people. Now I want to live on a desert island. Humans are trash. If we all had the same skin color, religion, and star sign we'd start discriminating by hair color next. The only thing keeping me sane is the idea that most humans are trying to do good and it's a minority of people that hate others.
Stop worrying about 'humans' and concentrate on yourself, and the people close to you. Yes, humanity is shit. Life is unfair, and the world only really 'works' for about 5% of the people in it. That ain't your problem to fix and it ain't changing in your lifetime.
Just be responsible for your own energy. The rest is for someone else to worry about.
I've actually stopped caring about climate change. Humans deserve what we get. I'm actually grateful that tech industry is looking into robotics. After we as a species die out the robots, our successors, will have our collective memory and I think they'll do a hell of a better job running things than us.
Climate change is a done deal. It's going to happen, it's going to be unprecedented, and again, there's nothing you can do about it. Focus that preservation energy on you and yours as it is needed.
I'm afraid the robots don't fully mature and there will be no collective memory. We ain't the first people to make it this far in the run, but if you don't carve it in stone, it doesn't survive the reboot.
(I'm joking about the last robot bit, but it's an interesting idea!)
