The panda is one of the animals most in danger. Three are about 1,000 pandas living in nature reserves today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live and more baby pandas are born in the zoos.
Pandas live in the forests and mountains of Southern China. They mainly live on bamboo, and each pandas needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don’t have many babies, and baby panda often dies. The situation is becoming very serious.www.21-cn-jy.com
Our government is working hard to save pandas. There are more than 30 nature reserves to protect pandas but these are not enough. The government has made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.21·世纪*教育网
