“The intelligent, social, ocean animals kept in the most pitifully small tanks at SeaWorld are denied everything that is natural and important to them. In the wild, they swim up to 100 miles a day in the open ocean, but captured dolphins are confined to small tanks where the reverberations from their own sonar bounce off the walls, driving some of them insane. Some of these animals were violently captured from their homes, many are forced to learn circus-style tricks, and according to whistleblower tips from trainers, withholding food and isolating animals who refuse to perform are common training methods. The only thing that people learn from visiting a SeaWorld theme park is how miserable life is for animals held there.”
