Will I visit the zoo again?

My 3 year old asked me recently when we will visit the zoo again.

I told her one day soon but internally I am unsure as to what my feelings are about zoos, aquariums, circuses and the like.

On the one hand they provide education up close and personal of animals people would never otherwise have a chance to encounter. It is fascinating to see them live, and not just on TV. You realize their enormity and beauty among other interesting aspects.

What causes me to hesitate in the wondrous world of these places are the very real horrors that go on behind the scenes, at least in some of these places, I assume.
