I don't know if people realize the groundbreaking work that was done at Sea World in the 70s with animal training, and how it essentially forms the basis for all modern animal training today (of course, they were building on Skinner). Positive training *comes* from training marine mammals, because you can't use negative training on an animal that can just swim away from you. Those shows aren't just for human amusement - we've learned an incredible amount about how animals learn (and of course, since we are animals, how WE learn) from these kinds of progams. If anyone has ever recommended you clicker train your dog, they have Sea World to thank for pioneering this method.

I'm not a fan of circuses since I believe there the care of the animals is an afterthought. I also believe a lot of zoos used to be like this, but I think most zoos have come a long way in the past twenty years.
