Wetlands ! Valuable Resources on the Earth

     There are many wetlands in China and some of them have become the world's important wetlands.

The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are

home for many different kinds of animals. The world's largest Milu Deer Nature Reserve is in them. More

than 700 Milu deer live freely there. There are not many red-crowned cranes in the world, but every

winter you can see some in the Red-crowned Crane Nature Reserve in the Yellow Sea Wetlands.

     The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and

sunshine, too. They are really good places for wildlife. Offering (提供) food and home for some special

farms and less space for wildlife.
