We can't ... and that is the problem. And that is why CITES is nonsence. There is no point in "protecting" animals and/or plants from being collected and/or traded AS LONG as you don't protect their habitats. And as we agree on the fact that MAN will never stop destroying the habitats ... for many reasons ... it is obvious that CITES is a nonsense law. The idea behind it may be great ... as is the idea behind ... but it JUST DOESN'T WORK.
