Secondly, one may support keeping animals in captivity because they provide a controlled environment within which they can receive the necessary care (Doyle, 2017). For instance, sick or injured animals can be monitored best in enclosed spaces where caregivers can provide them with proper medical attention. Such vulnerable animals would not survive on their own in the wild, and the zoo environment saves them from danger as they recover from illness or injuries. With climate change ravaging natural habitats and making food scarcer, zoos help ensure that these animals do not starve to death as there are numerous workers assigned to take care of their water and eating needs.
