Anarchists have been sounding this alarm for years but because we are so disorganized and exists from socialists to capitalists it's hard to ever congeal but this shit has been going on for 20+ years.
They start by saying YOU are the source of global warming via vehicles, diet (meat) etc. They say there isn't enough to go around. The problem with this, is there is far more than enough to go around and sustain humanity. By models we have, the earth can sustain up to 20 billion humans. The problem, corporations create 90% of our emissions with 3/4 of those emissions created specifically from the global military industry.
They've sold you on the lie that people are the problem where people aren't.
The biggest buyers of the propaganda are Americans.
I hate it but Americans on both sides swallow propaganda left and right. The USSR won that battle years ago and nobody realizes it.
