like full of powerful mistakes but i will jump in with the fun facts about the amazon one and how this is maybe the dumbest point on this, so like the amazon is a weird biome like because you would assume hey the soil must be great and that is why there is so many plants in there but actually the amazon soil fucking SUCKS SHIT LIKE IT IS BAD but there is like an layer of dead things over the soil like leaves and animals and stuff that is basically where all the nutrients come from so even if he was correct about it more o2 would not make a new one because how it was made was because there was this piece of land that was left untouched for thousands of years with mostly nomad societies living on that place so no real human modifications on that bad boy for thousands of years also this is why fires in the amazon are really bad because that whole organic layer will just burn with the trees so reflorestation is kinda complicated and if we ever get to natural wildfires feedback cycle in there it would be kinda fucked to stop that from just becoming a desert
