What Lessons Should Be L earned From the Drough t

　　The drought in the south-west China has lasts for several months, which makes people face water and food scarcity. We should learn lessons from it.

　　The drought can be cause by several factors.  Firstly, about 63 percent of cities in China are facing water scarcity.  The situation is worsened by pollution a nd industrialization. In addition, too many trees  have been cut down, so forest cove rage has been decreasing rapidly. What's more, some water conservation projects haven't been functioning properly, thus  people there have had to rely more heavily on rainfall for their water supply. Most of China's irrigation systems are very old.

　　In order to prevent this case coming about again, we should improve our awareness of saving water, makin g proper use of water and recycling water. Meanwhile, we ought to plant more trees and protect environment to  prevent loss of water and soil erosion. Of course, the  governments should increase investment and repair water conservation pro jects as timely as possible.
