In the UK zoo inspectors will go and check on zoos incase they are mistreating animals. There are numerous laws to protect animals:
Recently zoo inspectors said they had found “significant problems caused by overcrowding, poor hygiene, poor nutrition, lack of suitable animal husbandry and a lack of any sort of developed veterinary care” at South Lakes Safari Zoo.
The Guardian reports that one African spurred tortoise named Goliath died after being electrocuted by electric fencing, while the decomposing body of a squirrel monkey was discovered behind a radiator. The zoo had a death rate of about 12% of its animals a year. Can you think of any more pros and cons of keeping animals in zoos?
Religions have an opinion on zoos too: how do their teachings affect what they think of zoos?
