Specifically, I would like to question if Brazil can or even should be trusted to handle the Amazon forest in a responsible manner. Over the past decades, objectively, it has shown that the country, or maybe primarily its government, doesn't: The forest is continuously decimated, ever faster, with full and open support by the government itself.
Considering that the Amazon is of broader concern than just Brazil's jurisdiction alone, would it -- and I'd include other, similar areas around the globe here too -- make sense to move administration to a more responsible body, the UN for example (not specifically the UN, but you get the idea)?
This may sound offensive to you for all kinds of reasons, especially if you're Brazilian, and I sincerely apologise for that. But please consider that maybe the challenges ahead of humanity as a whole require new solutions, new ways to think about who "owns" land?
