Animals can accomplish great things with Humans if they are treated with respect and the conditions are not cruel. If they are not treated with respect they will defend themselves. I'm not against Circuses and Zoos, and that you would shun someone's tragic accident because of some self righteous misguided ideal shows us the true cruelty of humans. Nature can be cruel, it can and has wiped out whole civilizations.
"Oh, wild animals don't belong in zoos, we shouldn't even bother trying. Humans don't belong in space, let's not bother with that too, and if someone launches a rocket and gets stuck in space, well that their fault and I could care less."
In older more serious days, a person who sided with nature and animals vs their fellow man would be tarred and feathered, if not taken out and shot. Just be sure you never do something stupid, like put your hand into a hole and get bitten by a snake, because fools don't have friends, but are laughed at and ridiculed by all. I don't care if you don't like me, but you can all take that attitude and shove it. Depending on the circumstance, yes I would feel sympathy for the trainer and yes I would wonder why it happened.
I forget myself and that this is a place for people with a defeated mentality. I rest my case. Shall we abandon all zoos?
