Let me interject some additional reality....
You won't be able to long term save any species in captivity. You don't have enough people to do it. Plus, you can only use similar environments to where they came from, not the real one. You will change the animal. You won't have enough people to keep meaningful,viable populations. Basically, as any REAL conservationist and/ or scientist would know, you can't save the animal without saving the habitat. You have lost once you lose the environment's effects on its existence. Once you separate the animal from the habitat, it truly ceases to be what it was. It becomes a pet. Or a curiosity. Or nothing. We have far too many of those.
