I agree with this in theory but if it wasn't for wild imports then aardwolves, aardvarks, certain civet species and countless other none-threatened species wouldn't still be in captivity.
Well, ok, that might be true. But what is the ethical underpinning there other than 'we want them in zoos'?
It's not a loaded question - I'm not going to backbite in response to your answer. But it's a live question I think.
