Here are just a few laws that zoos have to follow: 1. Animals are not allowed to be used for performing purposes e.g monkeys riding bicycles. 2. All sick or injured animals cannot be on exhibit. 3. Every boundary wall around the enclosure has to be at least 2 metres high. 4. Every zoo must have at least one trained veterinarian. 5. Any completed zoo exhibit should provide the public with understanding of the animals, themselves and the environment. 6. All zoological collections must show a strong commitment to conservation and education. 7. All zoos must uphold high standards in animal welfare and public safety.
I think laws are very important not only for the animals safety and wellbeing but also for the humans safety.
