In principle a nice idea, as we all depend on that forest, however, people like that would abuse this and extort other countries and demand more and more.
Bolsonaro is also simply wrong to claim that it is their forest, only because it is on Brazil ground. The whole world depends on it, so it must be a resource shared and kept up by all. Bolsonaro and people like him are holding such things like rain forest hostage.
Please send in the military or something to wrestle control over such a valuable thing from that insane person. We can not afford to be extorted by the likes of him on a global scale, when time draws near, where the future of the whole species will be decided.
