Aquariums and marine-mammal theme parks are also guilty of unethical treatment of animals. For example, Sea World takes orcas, dolphins, and many other sea creatures from their natural home and places them into tanks that feel like bath tubs to them. Orcas and Dolphins are social creatures and when places like sea world take them out of their habitat, they are taking them from their families too. Not only are the tanks extremely small, the water also contains harsh chemicals that have been known to cause blindness in dolphins and even causes their skin to peel off. These places are just as bad, if not, worse than zoos.
