Your worldview is very very very narrow. The reality is that kids who don't visit zoos, or farms grow up not caring at all about animals. Because to them animals aren't "real", they are these distant things that have nothing to do with them.

On the other hand when they see conservation status "threatened" on the sign by the animal they wonder about it.

And there's nothing wrong with putting an animal is a zoo - you are correct, they don't behave the same. But that doesn't make it wrong. Animals are not trophies to be displayed in the wild and always to be some distant unknowable thing.

Instead animals and humans share the same planet and we should encounter them up close, and experience them, and zoo's are how you do it.

You are relegating animals to these "things" that no one ever sees or hears about - or cares about.
