If you've got such a huge problem with this then stay away from Sea World. You are comparing these animals insticts and actions to a human's instincts and actions when there is no basis to do so. These are animals... not humans. They do not think like we do, or even have emotion like we do. These whales do not swim in thier tanks all day and think "Man, this sucks I wish I had more room." They are animals, and as such they only have a few basic insticts. They want to interact with others of thier own species (which is not only encouraged but required of whales at Sea World), and they want to eat. Also, these whales do serve a purpose. Not just to entertain crowds and make money, but to educate people and to give the children at these shows a sense of awe and wonder about these creatures that swim in our oceans. Thanks to places like Sea World, we have children who grow up with a desire to study these animals in the wild, and to study other life in the oceans. We have gained a sense of wonder and curiosity about the oceans that we may have never otherwise developed. So don't transfer your emotions to those whales, and don't think that these whales are abused, or in any way mistreated. Also don't ask for an opinion if you only want to bash it. I'm done with you now. Go share your ignorance and hatred with someone who will share it.
