Correct me if I'm mistaken, but isn't Brazil currently losing huge tracts of protected rainforest in those areas, just because of Bolsonaro's politics? How is he managing to undermine these protections so totally?
We're all learning in the past few years how quickly institutions can fail when you have bad faith actors at the highest levels. In this case he can do a great deal of damage simply by openly being against environmental causes, because it sends a message that the laws will not be enforced, even before he started actually dismantling the laws.
