> One effective way to discourage this is put a worldwide ban of exported wood from Amazon. If major countries can come together on this then this could actually work.

Tell that to the ivory poachers. All a ban accomplishes is turning an industry that has demand underground, meaning they can now operate off the books, illegally, not pay proper wages, operate completely without regulation and if they run into competition, instead of working side one another they often kill each other.

Prohibition has literally never worked for literally anything.
