i'm just typing the way i de-romanticize them. we don't know much about their culture nor how much effected Amazon's biodiversity. what if it had twice the amount of species before their extensive practice of growing hyper dominant species? 11,000 years of human settlement on a land that evolved for millions of years in various separated isles that later got together via geologic events (thus the rich biodiversity of the region) can have a great impact

from the very 1° comment i made i typed a (probably) when i touched this subject. if Europeans took indigenous knowledge to their land, maybe Europe forests wouldn't be ripped out. maybe it wouldn't work because their ecosystem. who knows. i'm not comparing indigenous people to anyone, i'm just trying to reflect they weren't magic saints of the forest as people portray. as a vegan i also dismiss a bunch of their living practices

also California has nothing to do with the Amazon. that land catches fires naturally by lightning. various places that this phenomena happens evolved to deal with it. have you ever been to Amazon? it's so humid. regions of "terra preta" (indigenous practice of making the soil fertile, which involves burning) allowed them to grow various stuff but again, they were into hyper dominant species not expanding the forest (i guess). and as far i researched, terra preta regions are less than 2% of the whole Amazon forest
