We see wild animals in captivity at a wide range of venues—zoos, circuses, aquariums, safari parks and even museums. But is keeping animals in captivity for scientific or educational purposes justifiable or even necessary?

In 2017 the Phillip and Patricia Frost Museum of Science opened in Miami. More than 300 million dollars were invested in this project. Its main objective is “to disseminate scientific knowledge and to help the conservation of the environment.” One of the highlights of the museum is a massive seawater aquarium that houses a variety of marine animals—even hammerhead sharks.

Critics question whether such exhibits are the best way to educate the next generation and if it they inflict unnecessary pain and suffering on the animals in the exhibits.
