Zoos are complex places - literally. Each time I enter one, I'm filled with a nagging ambivalence between competing views and emotions. On one hand, I think about the animals forced to live in enclosed compounds far from their natural setting. But on the other hand, I'm filled with childlike awe and wonder as I watch gorillas, elephants, hippos and the many bird, amphibian, reptilian and mammalian specials that I'd never even heard of.
