Animal rights and welfare has open to debate in recent years,while extinction of many rare animals results from extremely development of industry has arisen as one of the hottest topics.There is much controversy over whether keeping animals in the zoos is inhuman or protecting them.Considerable though the drawbacks that locking animals in the zoos leads to are,they can not compete with the benefits that protecting the rare species in the zoos brings about,when species conservation and scientific research,economic benefits and education meaning taken into deliberation.
Keeping rare species in the zoos is the best way to prevent them from extinction.With long-period of development of industry,a huge amount of pollution like carbon dioxide and other exotic chemical liquid and air released to the atmosphere which caused lots of animals barely died out.Because of one species’ extinction,it can cause next species in the food chain too much or barely die,which finally have an extraordinary influence on the human being.
Therefore,it is imperative that rare wild life should be carefully protected in the zoos.
Scientific research on animals in a comfortable way can help human find both origin of human being and the future medical technology of well being.Despite the amazing speed of the development of the medical technology which is less pain,it is still inhumane that having medical experiment practice on human.Due to resemblance to humans,animals can respond similarly to external disturbances like human,which can give human lots of space to do the scientific research.Consequently,the final success on animals experiment can benefit both humankind and animals themselves.
On the other hand,the proliferation of tourist attracted by the rare wild life in the zoos can boost the economy and generate much employment opportunities.Further more,visiting the zoos and grabbing the knowledge about the animals is a vivid education for children who will,because of this,love the nature.
From what has been discussed,animals are key component of the whole natural order and they can be taken as resources intended for the benefit of humans.

答案和解析
Spending an afternoon staring at monkeys, bears, zebras and other animals can be fascinating, but critics of zoos argue that locking up wild animals in zoos is unethical. Proponents of zoos counter that zoos help educate people and provide a haven for endangered species.
Pro: Saving Endangered Species
Supporters of zoos argue that they help save endangered species. Zoos provide a safe place for endangered or threatened species to live. Zoos also encourage the reproduction of endangered and threatened animals, helping ensure that these species don't die out. For example, according to GoodZoos.com, zoos have saved some species of bison and oryx, as well as the Jamaican boa, Hawaiian goose and Mauritius pink pigeon.
Pro: Educational Opportunities
Zoos educate children and adults about animals and biology, inspiring people to study science and promoting an awareness of ecological and conservation efforts. Observing animals is more inspiring and memorable than reading a textbook or watching videos. Zoos also provide educational material, offer demonstrations and provide internship opportunities, and they make it possible for scientists to perform research on animals.
Con: Animals Suffer
Animals suffer in zoos. Many are kept in small enclosures to ensure that they are close enough to the visitors. They don't get to hunt for their food and may have to live in a different climate than they are accustomed to. Birds may have their wings clipped, while aquatic species may not have enough water to swim freely, according to Dr. Thomas Dixon. Making animals suffer for our enjoyment and entertainment is unethical, according to zoo critics.
Con: Zoos Don't Counter Habitat Loss
Even if zoos provide a safe place for endangered species, they do little to counter habitat loss, the leading cause of endangerment. In addition, zoos may distract from other conservation efforts that have more of an impact, such as land conservation programs. Finally, according to Dr. Thomas Dixon, breeding animals in zoos often involves inter-breeding, because of the small animal population, which causes birth defects.
Con: Research and Education are Limited
Although scientists may perform research at zoos, they can also perform research in the wild. Research performed in the wild may be more accurate than research performed on animals in captivity, because zoos change how animals act. In addition, according to critics, some zoos focus more on entertainment than education; many zoos do not perform much research and may design programs in order to captivate and entertain visitors, not educate them.
