alt Hacker NewsYou said certainty but now you say probably. Which is it?
I never claimed that they had no impact, but it is clear that the impact tended towards neutral to positive because: a) the forest was still there; and b) it had the higher rate of biodiversity in the world.
Indigenous burns in California are recognized as being a net positive for the old growth forests and the biodiversity within. It doesn’t take a lot to extrapolate that the same was true in the Amazon.
To state it a different way: yes, of course and without doubt their very presence affected biodiversity.
But you were talking about their practices, which tended towards custodial over exploitative. And overall these practices clearly supported biodiversity as a whole, otherwise we wouldn’t note the biodiversity of this region as anything special (see again the quote I took from your first article).
I apologize anyway for my slightly combative tone. I appreciate the resources you shared even if I haven’t had time to absorb them in full yet.
