A number of people believe that cruel zoo should be closed down has become a prominent point of content in modern discourse. However, others contend that zoos are useful for protecting wildlife animals. Overall, I completely agree with the second view.
On the one hand, animals can be harmful. The government can see opportunities to earn money from illegal activities to attract visitors. They can be starved if they have against behavior. This leds to animals have adverse impact on their health. In addition, if investment source is not enough, these facilities and space are limited. As a result, the fund of country is wasted, economy slowly rise up.
On the other hand, the problems related endangered animals increasingly become serious issues and inhabitants are affected. So zoos can be safe for them and do not suffer from hunting, chasing. To illustrate, pandas in China are entered red list, and scientists and zoo made an effort to protect these animals. Moreover, zoo help raise awareness of protection of animals. Therefore, people can understand fully about the purpose of zoo.
Inconlusion, both views are valid to extent, ai still opine that zoo is useful to protect wildlife animals.
