Personally, I don’t think I would do well in a cage and I’m a fairly domesticated animal, so I have a bit of empathy for that big cat that is pacing back and forth in what looks to me like quiet rage, or those apes, LOL, that throw their shit at the audience, or the llama or camel that lures a human close by looking all cute and friendly, then spits a huge loogie on them or bites the hand that feeds them. LOL. I think it is good, though, that humans get some exposure to the wild life. But we could do better.
I think Busch Gardens has a better idea—A vast, natural enclosure where the animals have enough room to migrate, have families, form herds, live out more natural lives with a monorail above that humans can observe them from. Isn’t that what we really want to see? To watch them in their natural habitat doing their thing unmolested? We can get the up-close shots on film. We can see the births on closed circuit TV live from around the world.
That’s the way to do it, I think, with a little education on their endangerment and need for protection and conservation quietly slipped in over the intercom along with interesting facts and descriptions of unique behaviours.
