【正文】 China has large desert areas and much of its agricultural land is being threatened by desertification(沙漠化), which is getting worse. In addition, soil erosion has led to a huge loss of farmland and the drying up of rivers. Consequently, the livelihoods of 35 million people are being threatened. Furthermore it is even affecting cities. The nearest sand dune is less than 100 miles from Beijing, Where unpleasant sandstorms are being more frequent. The worse the situation, the more pressure there is on the government to take action. The reasons for the changes are plex(復(fù)雜的). It is clear that pollution of air and water by factories is affecting the environment. Trees and other vegetation die, and so soil is eroded. The more trees die, the less water is held in the earth. The need for wood, fuel and buildings leads to further deforestation(采伐森林). Which cause further soil erosion? Local farmers find it more and more difficult to make a living. They end up using inefficient farming methods, which again leads to soil erosion. The government is carrying out antidesertification project, including the creation of a forest belt around deserts. The treeplanting campaign, known as the Great Wall, is meant to protect Beijing from sandstorms.
