Read the excerpt from “A Case Against Zoos.”

The idea of keeping any living creature behind barriers is difficult for some people to accept. It’s true that zoo animals receive medical care. But zoo supporters claim that animals in captivity are even healthier than those in the wild. Let’s consider a few problems with this argument. First, animals like polar bears live naturally cold climates. However, there are polar bear exhibits in warm and even tropical areas worldwide. It is very stressful for animals to adapt to different temperatures and this affects their health. Next, no matter how hard they try, zoos cannot provide the living space that animals need. Studies show that small enclosures prevent animals from getting enough exercise and carrying out normal routines. Lack of space even lowers infant survival rates. Zoo diets may not contain the nutrients animals get in the wild, causing disease and weight problems. Finally, the life span of some species, such as elephants, is shorter in zoos.
