Zoos are hugely popular attractions for adults and children alike. But are they actually a good thing?
Those people who are against zoos, would argue that animals often suffer（遭受痛苦）physically and mentally by being enclosed. Even the best man-made environments can’t come close to matching the space, diversity（多样性）, and freedom that animals have in their natural homes. This causes many zoo animals to become sick. Catching animals in the wild also causes much suffering by separating with dolphinh family. Some zoos make animals behave unnaturally. For example, ocean parks often force dolphins and whales to perform. These sea animals may die years earlier than their wild relatives.
On the other hand, by bringing people and animals together, zoos can educate the public about animal protection and encourage people to save animals and their homes. Some zoos provide a safe environment for animals which have been mistreated in circuses, or pets which have been given up and no longer wanted. Zoos also carry out important research into subjects like animal behavior and how to treat illness.
One of the most important modern functions of zoos is supporting international breeding（繁衍）programs, especially for endangered species（物种）. In the wild, some of the species have difficulty in finding mates and breeding, and they might also be hurt or even killed by people. A good zoo will enable these species to live and breed in a safe environment. In addition, as numbers of some wild species drop, there is an increased danger of populations becoming too genetically（基因上） similar. Breeding programs provide a safeguard: zoo-bred animals can be put into the wild to increase genetic diversity.
However, those people who are against zoos say that many zoo-bred animals are not put back into the wild. A lot of animals are sold not only to other zoos but also to circuses in the US or wild parks in South Aften, these some people are willing to pay a lot of money for the chance to kill a helpless animal. Often, where animals are familiar with humans and have very little chance of escaping.
So, are zoos good for animals or not? Perhaps it all depends on how well zoos are managed, and the benefits of zoos can surely outweigh their harmful effects. However, it is understandable that many people believe enclosing animals for any reason is simply wrong.
