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 important of wetlands and wildlife. Every year， on February 2nd， many activities are held to tell people more about wetlands.

Nowadays, too much carbon dioxide makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet and ourselves, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life, we’d better save energy as much as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don’t do the cooking with electricity.
To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don’t know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian (素食主义者) can help reduce one and a half tons of carbon dioxide a year. Maybe it is a little difficult, but it’s really necessary.
To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportations (交通工具). On one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It not only waste money but also causes trouble to the earth, because making everything will produce carbon dioxide more or less.
There are many other ways to live a low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on.
