How could we possibly think that keeping animals in cages in unnatural environments-mostly for
entertainment purposes-is fair and respectful? Zoo officials say they are concerned about animals. However,
most zoos remain 'collection' of interesting 'things' rather than protective habitats (栖息地).
Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.
Zoos claim to educate people and save enered species, but visitors leave zoos without having leamed
anything meaningful about the animals' natural behavior, intelce, or beauty. Zoos keep animals in small
spaces or cages, and most signs only mention the species' name, diet, and natural range.
The animals' normal behavior is seldom noticed because zoos don't usually take care of the animals' natural
needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and
physical exercise. This results in unusual and self-destructive behavior called zoochosis. A world-wide study
of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed
that elephants spend 22 percent of their time repeated head movements or biting cage bars, and bears
spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
Furthermore, most animals in zoos are not enered. Captive breeding (圈养繁殖) of enered big
cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot
about their captive breeding programs because they do not want people to worry about a species (物种) dying
out. In fact, baby animals also attract a lot of paying customers. Haven't we seen enough competitions to name
baby animals?
Actually, we will save enered species only if we save their habitats and put an end to the reasons people
kill them. Instead of supporting zoos, we should support groups that work to protect animals' natural habitats.
