10/20 Size of Zoo's enclosures
Considering the needs of both Zoo animals and visitors. I believe all zoos must provide spacious enclosures. The most obvious reason is zoo animals need enough space to exercise. Just like humans have obesity problems, animals also can experience this. Regarding mammals such as elephants, apes, and zebras, science research shows that captive animals are 4 times more susceptible to cardiovascular disease than wild ones. My second reason is some of the animals are so sensitive. They have better sensors than humans. If the visitors are making a loud noise and engaging in bad behavior, these animals may get stressed or anxious. For these important reasons above, I think zoos should build bigger enclosures for zoo animals.
