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 Yancheng，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 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(野生生物)．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．
The Chinese Yellow Sea Wetlands are in the________of China．

Not many years ago，some farmers were worried because hawks were taking many of their chickens．The farmers didn’t know what to do．Finally they went to the country officials and asked for help．
“Kill the hawks，”the officials said．“We will even pay for them．”So the farmers began to think of ways to kill the hawks．
The farmers killed many hawks．They no longer had to worry about their chickens．But they now had a new worry．Field mice were eating up a lot of the farmers’grain．
How did this happen？
Hawks eat not only chickens but also field mice．They eat more field mice than chickens．But the farmers didn’t know this．When they killed a lot of hawks，they changed the balance．
When people move into a new place，they often destroy many wild plants．Often these plants are food for the animals．If the animals can’t find enough plants to eat，they will starve or have to leave the place．
In one part of the USA，for example，the deer there like to eat a certain kind of wild roses．The mountain lions there eat the deer．The number of deer，mountain lions and wild roses doesn’t change much if people leave things as they are．
But people killed many mountain lions in order to protect the deer．Soon there were so many deer that they ate up all the wild roses．Then the deer began to eat the green leaves of young trees．These trees were important to the farmers．So the farmers thought of ways to protect their trees．Now the deer had nothing to eat，and many of them died．This was another lesson from nature．
To keep the balance of nature is important for us to rememher．
