Dongting Lake is the second largest freshwater lake in China. It lies in the north of Hunan Province. It is famous for its beautiful scenery and plenty of plants and animals.
It is like a shining pearl in the middle of China. In my opinion, the most beautiful place is Junshan Island with its clear water. However, there are many problems. People change some of it into land for crops. And they also take too much water and fish from the lake. To protect it, we should make less pollution and have some rules to protect it.
In a word, it’s our duty to protect our natural treasure like Dongting Lake.
