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.

Zoos can help to save endangered species by keeping them in a 'safe' environment. Safe as in protected from poachers, predators, habitat loss and even starvation. If a zoo has a breeding programme, this is another way to protect endangered species which may have trouble finding suitable mates in the wild.

Many zoos have improved enormously; the better ones being crucial in saving species that would have otherwise gone extinct. Nonetheless, for some people the mere word zoo carries impressions of old zoos, bad zoos, circuses, and theme-park shows that many find distasteful. Good zoos know they must innovate forward.
