It's really a sad little pretzel of hell that we (supposedly) need to create economic incentives for every human on Earth to not squander their local resources for short term gain when it is in fact economic incentives that got that ball rolling downhill in the first place. But yeah, I guess we'll find a way to throw globalism and money at a problem created by globalism and money.
But it's important to recognize where capitalism fails (tragedy of the commons situations, negative externalities) and address those.
Something like this exists in the Amazon Fund. Unfortunately it seems like it has broken down lately:

I think the state should take on that role, but there needs to be a strong inventive for them to want to protect it.
Brazil would never tolerate that, nor should they.
On the other hand if you want to buy huge tracts of the Amazon and pay private security forces to protect it, that's doable.
Better though would be to make it in Brazil's interest to protect the Amazon. We all benefit from it being intact, so we should all chip in to create an economic incentive for the county of Brazil to maintain it.
