Animals in captivity across the globe have been documented displaying signs of anxiety and depression. In fact, psychological distress in zoo animals is so common that it has its own name: Zoochosis.
Animal abuse is widespread in 75% of zoo and aquarium facilities. 96% of elephants in entertainment facilities are treated poorly. Polar bears have a million times less space in zoos. Only 18% of captive animals are endangered.

Polar bears are the animals that do worst in captivity. Carnivores such as polar bears, tigers, cheetahs, and lions are especially poorly suited for life in a zoo, according to a new study. The more an animal roams in the wild, the researchers found, the worse it fares in captivity.
That captivity can be REALLY bad for both physical AND psychological health. And while zoos have been really helpful is saving endangered animals, it doesn't work out for certain species. For example, most large carnivores like lions and tigers that are bred in captivity die when released into the wild.
Research has found the effects of captivity so detrimental, it can actually cause physical changes to brain structures, which can alter health and behavior. When animals are denied the ability to live sensory rich lives, and their experiences are limited to the dullest, most blank canvas, mental illness develops.
We have no evidence whatsoever that wild animals are, in any way, happier than domesticated ones which are treated well. One of the consequences of domestication is a decrease in stress across the board.
Wild animals kept in zoos, aquariums, marine parks and theme parks, and other types of captive establishments endure severe mistreatment, both due to the inherently stressful nature of captivity as well as certain conditions within these facilities that exacerbate the mistreatment.
Six Species Saved From Extinction by ZoosAs of 2017, 1,000 animals had been restored to the wild, while thousands more were living in zoo environments. Przewalski's Horse: The only truly wild species left in the world, Przewalski's Horse is native to the grasslands of Central Asia.
More than 80 percent of mammals survive longer in zoos than in the wild. This was true even of carnivores, according to study co-author Marcus Clauss, professor of nutrition and biology of zoo and wild animals at the University of Zurich.
AZA-accredited zoos and aquariums have collaborated on breeding and reintroduction programs that have helped save at least nine species like California condors, black-footed ferrets, Przewalski's horse, golden lion tamarins, American red wolves, and more from the brink of extinction.
A Change In BehaviorAs an animal's brain changes, so too do their behaviors. The primary change is that animals lose their some of their natural behaviors including food-finding, avoiding predators, and rearing young, and replace them with stereotypic, destructive behaviors brought on by chronic stress and boredom.
Do zoos help or harm animals? While some suggest that zoos exploit captive animals and that wild animals should be wild, these facilities also present wildlife conservation attempts and learning opportunities as well. Zoos may introduce trauma to animals, but they are also taken care of in zoos.
While zoo advocates and conservationists argue that zoos save endangered species and educate the public, many animal rights activists believe the cost of confining animals outweighs the benefits, and that the violation of the rights of individual animals—even in efforts to fend off extinction—cannot be justified.
Zoo's Research Helps WildlifeStudying animals in zoos can create real positive change for wildlife populations. Even if animals in zoos are never introduced to the wild, they still help improve the lives of their counterparts living in nature.
According to National Geographic, Zoochosis is a neurological disorder that plagues nearly 80 percent of zoo animals, and is characterized by symptoms of anxiety and depression in zoo animals.
The vast majority of the animals held captive inside their compounds are depressed. They live in perpetual captivity and lack access to all of the things that make life interesting and enjoyable. And, often, they die far earlier than they would if they lived in nature. As it turns out, zoos do far more harm than good.
