Every month, junior high schools in China choose one hero of the month. This person is a hero because he or she has done something to help protect animals in danger. Huang Jing decided to write a letter to the President of China.


Dear Mr. President,
I have been doing a project at school recently about animals in danger. I think the situation all over the world is really terrible. I am writing to you to suggest what China should do to help protect animals more.
I know that there are nearly 2,000 nature reserves in China, which is good. I live in Beijing and there are about 30 reserves outside the city. We visited one of them last month to see for ourselves.
I feel so sorry for the giant panda. It’s one of the most popular animals in the world and a real symbol of China. We learned that pandas mainly live on bamboo, and that a panda can eat half its body weight of bamboo in 24 hours! That’s a lot of bamboo. I think we should try to do more to stop cutting down forests. Pandas are already a rare animal and it would be so sad if they became extinct (灭绝) forever.
The other animal we should try to protect more is the Chinese alligator (扬子鳄). These creatures live in some parts of eastern China. These beautiful animals live in freshwater rivers and lakes but the water in some places isn’t clean enough for them to live in. It’s really dirty in fact. The government should stop factories polluting the lakes and rivers.
If we protect these beautiful animals in China, more foreigners may wish to visit China to see them. They could be an important tourist attraction. It would be good if more people came to visit our beautiful country, especially to see the quieter areas in the country. Now most visitors just see the cities.
I hope you will encourage more people to think about such an important subject.
Sincerely yours,
Huang Jing
