Yeah I hear you. I know there are people that can keep them properly. But my thing is, why? These are majestic animals. They don't belong in a cage. I'd support them being kept in captivity, provided they have adequate enclosures. And I don't mean a cage where they could do a few laps. I'm mean large, open land, with perimeters, where they are free to roam. If they're going to be locked up, at least that is how these animals deserve to be kept. And quite frankly, who would be able to do that? Zoos can barely provide that. How many private facilities would have the means?
And this sort of leads me to that quote from Jurassic Park, from Ian who says something along the lines of people being so preoccupied with whether or not they could, they didn't stop to think if they should.
