I wouldn't believe if someone told me they've seen "After all, they're not doing anything to advance humanity technologically" spouted out in plain-sight internet and it wasn't a parody, so I'll just assume you're using really dry (actually excellent) sarcasm. In any case, just to counter the argument that they're wrecking ecosystems, why do the US get to have wrecked their ecosystems in the name of White Man's progress many decades ago and Africans can't?
