As soon as you can go to one of those places and see wildlife in the wild. It will change the way you look at them in zoos.

This is an interesting point of view.
I think the experience of seeing wildlife in the wild is a wholly different one to that of seeing it in captivity. Not better, not worse, just different.
There are plenty of analogous comparisons: the difference between seeing a sports event in the flesh, or on TV; watching a film or seeing a play; listening to a CD or seeing a band in concert.... and so on.
I think in all instances there is, perhaps, a belief that one choice - the wild, in the flesh, the play, the concert - is, somehow, 'better', or truer.
I would disagree, however. I don't think either is better - but they offer very different experiences. When I go to see Portsmouth play Carlisle later today, I will see less than I would on television, and possibly get a less good reading of the ebb and flow of the match, but I will gain in other ways: atmosphere, flavour, possibly even personal involvement.
Amongst my very best animal experiences have been in the wild. But spending several hours looking for a rare primate, and, at the end of that quest, being rewarded with a 45 second view before the animal in question bounds off into the forest, will never replace the thrill of seeing the same animals, or others, very close, and with ease, in a good and well-designed zoo.
