What about the title?

[v0031]

 There are many wetlands (湿地) in China and some of them have become the world's important wetlands.
The Chinese Yellow Sea Wetlands are among them. They are in Yaneheng, Jiangsu Province. They are home
for many different kinds of birds and animals. The world's largest Milu Deer Nature Reserve (自然保护区) is
in them. More than 700 milu deer live freely there. There are not many red-crowned cranes (鹤) in the world,
but every winter you can see some in the Red-crowned Cranes 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 food and home for some special kinds of animals and
birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent
flood. But some people want to change the wetlands to make more space for farms and buildings. This means
there will be less and less space for wildlife.
     Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year,
on February 2nd, many activities are held to tell people more about wetlands.
