　　The survival of about one fifth of the world's vertebrates—animals with a backbone，is considered threatened, according to new research published in the journal Science. That's a large fraction of Earth's animals, but this new study held some good news too.Conservation efforts by humans have slowed the loss of many species of amphibians(两栖动物), birds, and mammals. Losses in these groups would have been about 20 percent greater had it not been for recent actions of protection.

　　Among the animal­conservation success stories is one about birds called Mauritius kestrels. In the 1970s, just four of these birds of prey were left in the world. Through a special breeding program, scientists were able to increase their number to about 1,000 and release them into the wild.
