Many of today's zoos hope to stop or slow the decline of many endangered species and see their primary purpose as breeding endangered species in captivity and reintroducing them into the wild. Modern zoos also aim to help teach visitors the importance of animal conservation, often through letting visitors witness the animals firsthand. [38]
Where zoos permit visitors to feed animals, it is usually domestic animals such as sheep and goats, [34] as in this French zoo. Zoos generally discourage visitors from giving any food to the animals.

If anti-venom is unavailable, emergency hospitalization or a fasciotomy may need to be performed.

The zoo hypothesis assumes, first, that whenever the conditions are such that life can exist and evolve, it will, and secondly, there are many places where life can exist and a large number of extraterrestrial cultures in existence. [3]
Currently, the wild animals number around 1,000 individuals, with a further 6,000-7,000 in zoos and breeding centres internationally. [61] While captive breeding can be an ideal solution for preventing endangered animals from facing serious threats of extinction there are still reasons why these programs can occasionally do more harm than good.
