JT often gets the science wrong, but he know how capitalism screws things up. His explanation is just what I was saying. I must have it right.
But, does anybody wonder where the carbon sequestered by the Amazon goes? A mature forest is not a carbon sink. Contrary to internet pop science. A forest is a carbon resource at maximum capacity. If you want a forest to sequester wood you have to sustainably harvest the wood and do something like bury it in desert sands where in a few thousand years will become coal. Otherwise it rots as fast as it grows and the forest is net zero.
And no the world does not suddenly become a garden of Eden with capitalism gone. You can't agree with the sixth mass extinction, and also pretend the problem is not too many humans. It does not work that way.
