I don't particularly like the fact that these wild beasts are held captive either, but at a place like Sea World the pros far outweigh the cons imo. Not many folks are able or bold enough to attempt an excursion into the wild to familiarize themselves with the orca or any other marvelous predator that rules their domain in the wild. The majority of world population does not even get to see the way of wild - living in dense population centers and far from where these things take place.
Were it not for this and other public exhibitions, most folks would go about their daily business never considering the majestic beauty and value to our world of these and many other species of mammals, fish, ocean creatures... in the same way that when a visitor to the zoo becomes concerned with the possibility of extinction of the silverback, panda, snow leopard, etc... and becomes involved in the preservation process... because of Sea World countless future marine scientists have been inspired to leave their native Milwaukee and do something to better our world and God's creation. So it ain't all bad in my book.
I have the luxury of swimming with dolphins, sea turtles, multitudes of fishes and watching the entire food chain work uninhibited on an almost daily basis, because I live on the Atlantic coast and the scientists have done some good to preserve the balance of nature where it belongs around here. If it were left up to the politicians and businessmen without education and public awareness, my coast would be a polluted and lifeless oil sludge... it is an epic battle already going on between "progress" and mother nature.
So go to Sea World, see what you are missing and also what you are affecting every time you allow destruction to the earth's native habitats, and get involved in making a difference. The earth's future is not promised - it is a reward.
