(2025·南京三模改编)What if you could save an animal from extinction(灭绝)? A wildlife conservationist works to protect different environments and the animals that live there. This can involve making sure that habitats(栖息地)are safe from disease，harmful insects，fire and human destruction. He or she might also work to educate the public about the importance of caring for wildlife. A lucky，hard-working few might be part of a successful effort to bring a species back from the edge of extinction.

That was the case for wildlife conservationists at the San Diego Zoo，who have helped save several species from dying out. The giant panda's comeback is one of their more famous success stories. Working with experts in China，where pandas are from，the conservationists developed a milk formula for panda cubs that raised survival rates for cubs born in zoos from 0 to nearly 100 per cent! They continue to spend many hours each week observing pandas at the zoo，so that they can learn what pandas need to survive in the wild. Although giant pandas are still vulnerable(脆弱的)，they were removed from the endangered species list in 2016.
The California condor(秃鹰)has also rebounded，thanks to the work of conservationists. The California condor，a type of vulture and the largest flying bird in North America，was down to a population of only 22 in 1982. The San Diego Zoo Global Wildlife Conservancy collected those birds and began using special techniques to help them breed. They learned that the birds had very high levels of lead in their bodies. They figured out the problem was a result of the birds eating the remains of animals shot by hunters who had used lead bullets. The conservancy spread the word about using different kinds of ammunition for hunting. Now，there are 480 California condors，about half of which live in the wild.
A wildlife conservationist must earn a college degree，often in biology or environmental engineering. He or she should also be someone who cares about the environment，is patient and likes to travel. "It takes a special kind of person to do it，" says Mike Sides，an ambassador to the San Diego Zoo Global Wildlife Conservancy. "You have to really see the bigger picture and be able to step out of your bubble and look at others' needs ... It all comes from the heart."
Even if it's not the career you choose，you can get involved with conservation efforts. You can volunteer at a zoo，raise funds for charities that help animals and be mindful that the products you buy aren't harmful to wildlife habitats. "In any sense，" says Mr Sides，"if you're involved in conservation efforts，you're doing something cool."
