There is an ongoing debate over whether zoos are need or not. Some people might suggest that zoos are no prcatical funcation anymore because of high maintanence fees. However, on the contrary, I stronly believe that zoos are essential for both hunam and animal. The fundamental reason behind this is that zoos are educational and protect endagner animal.
First of all, visiting zoos are great oppurtunities for students and children to see varieties of wild animals. This is largley because zoos have lots of rare animals such as tigers, dolphins, and sharks, which hard to see in daily life. Thus, school boys and girls could observe these aninals life style and uniqe action. From my experience, when I was biology class, I had to research on pander. Although there was massive information on the online, my teacher wanted to me to observe real pander. However, observing pander in my daily life was impossible, so I visited the local zoo to see pander. I could reseach everything that I need and got A from my class. If there had been no zoo in my town, I would have had hard time to finish my research. Thus, zoos are still imporant for students who want to see wild animals.
Finally, zoos preserved endanger species. An important reason behind this is that zoos provided perfect conditions for animal to survive, such as well nutirient, regular temerature and surrounding. For example, the black bear which has been categorized as an endanger specy because of abuse hunting and invasion of habitant. Many employees of zoos started to capture black bears from the wild and tried to increase bears' number by providing perpect environments, such as protect bears from human and providing nutrious food. Few years later, the black bear did not regonized as endager specy anymore, and employees from zoo released black bear to its natural habitant. In this respect, zoos have important funtion to preserve endanger animal from extintion.
In conclusion, I fimly agree that zoos have essential position in the world because they are educational and protection from extinction. Accodingly, zoos serve practical function.
