The climate has always been in a state of flux. For as far back as e.g. ice core records can show, the temperature and weather and atmospheric gas concentrations have gone up and down and all over the place, for millions of years.
Despite that, here we are, supposedly at the highest point yet demonstrated of intelligent civilization, our species having overcome all of it--and there are members of said species like yourself, who are acting completely irrationally, against all historical evidence.
If our ancestors thought like you, they'd have all frozen to death in caves, and we wouldn't even exist. "Hey, Ug, baby, wanna start a fire and get it on?" "Nah, I'm grieving cause the wooly mammoth outside sneezed and blew some dirt into the lake. We're all gonna die anyway, so why bother having kids? Might as well go ahead and freeze to death now here in this cave."
Get a hold of yourself, before it's too late for you to make use of the limited years you have on this planet. Tomorrow isn't promised to anyone.
Seriously, now, you might actually be clinically depressed. It's very hard to think rationally or overcome irrational feelings when depressed. You're on the Internet, so google up the signs of clinical depression. If any of them apply to you, go get some help from someone trained to provide it. There's no need to suffer helplessly when we have tools available to help. Do something now, because no one else can truly help you until you decide to start helping yourself.
It just made me try harder, but I think every kid needs to get over that bridge to become a legitimate adult - to be faced with both success and failure, and realize you are only ever at local maxima, there is always another mountain to climb, and you do it to aspire to see more and further.
So what's left? People. We are the essence of anything meaningful on earth. Despite our negatives, we've managed to thrive and create meaning. We have a consciousness that transcends our own understanding, and in this we should embrace each other in hope that our future is better.
Perhaps your feeling is that you just don't like people, and need to find positive ways to interact with them so that you can see a brighter future.
The environment has suffered damage, and it is likely to suffer further damage in the short term, but the time to start fixing that is now.
If you're NOT giving up on the future just yet, you'd be much better off maximizing your impact on public policy (from municipal to federal levels) instead of trying to become an inert object.
You can be part of the solution without needless self-imposed extremism.
