I feel sorry for the peasants that still have hope. Humanity is fucked by its own hand in the name of private short term profit for a few thousand sociopath families.
We are for one reason or another wholly unwilling to forcibly disempower these people, forcibly shutter all non-essential (essential being medical supplies, baby formula, staple crops, etc, non-essential being playstations, luxury suvs, the most polluting livestock, etc) manufacturing, forcibly remove their hold on government and their own industry's regulators, and forcibly use their assets to begin to address the damage the owner class has done. It isn't even being discussed. It isn't even being considered.
Therefore, there is no hope. If we aren't willing to address the root cause, and we aren't, all our symptom chasing is just rearranging deck chairs on the Titanic. Hey, the capitalists have more bullshit to SELL world governments as the newest vaporware solution to their destruction! What is it this week? ~~Ethanol Hydrogen clean coal~~ oh yeah, planet scale carbon filters! Yeah that's the ticket! They're very expensive, that's what makes them good!
I've found peace with this. Even our level of carelessness with technologies we never considered the externalities of won't be enough to destroy all life on our Mother Earth. She will recover from us, just as she did from the Chicxulub asteroid and the mass extinctions before that. As the great George Carlin said, the Earth will heal itself and cleanse itself because that's what it is, a self correcting system that has been here long before us and will be here long after us.
We were just another mistake of biology. Just another failed mutation. An evolutionary cul-de-sac.
Homo-sapien is not unlike the trees from 300 million years ago that there were no biological mechanisms to decompose yet, which caused a massive ice age due to lack of atmospheric carbon. The carboniferous period, only we cause the reverse through insatiable selfishness.
