One big difference, I imagine, is the population that forest is being extracted for. The Amazon isn't only being extracted while sustaining 100s of millions of South Americans (prior to colonization AUS had fewer than a million inhabitants), but also serving the world's demands. So I think it's different although in balance both unsustainably.

Yes, it's a vastly bigger population now, mc32, and that's what is unsustainable. The vastly bigger population is still increasing at a rapid clip, but the forests and the oceans are not.
