Don't blame me for that "mass suicide" comment, that was someone else's unimaginative and disingenuous reduction of many possibilities (various ways population might shrink) into one -- the most ridiculous and easy-to-shoot-down one as a matter of fact, which is why I throw the "disingenuous" in there.
Nothing will be done to stop climate change. I'll bet you a million 2022 dollars, payable in 2050 in whatever units or quantity are used then. Nobody who actually makes or affects policy is reading what we type here, and they don't pay undue attention to how we vote either. So like I said, I'm not proposing a solution; climate change is happening; there's no rest of the sentence. (There's no "...unless we hurry up bla bla hey guys c'mon etc. etc.") Nobody was in charge of changing it and nobody is in charge of stopping it (because nobody is in charge, at all).
The only thing you can say with any certainty (and it's surprising how obvious it is to some and how unacceptable to others) is that since technology and human activity are what caused the problem in the first place, and since every single permutation of more of the same, including and especially those designed to make our activities more efficient (https://en.wikipedia.org/wiki/Jevons_paradox) will just make it worse, then the only plausible solution is LESS of that. Nobody wants to hear about less. Less is negative growth, less is a recession, and nobody wants to hear it, as I already said and as you and your fellow commenters and downvoters have amply confirmed. It's funny how smug you all are while being naive enough to believe that somehow the thing that caused it all will be the solution to it all. Bla bla same actions expecting different result bla bla insanity bla bla?
You'll understand if the rest of the human race isn't quite as edgy and nihilistic as you are.
