What Lessons Should Be Learned From the Drought
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 and industrialization. In addition, too many trees have been cut down, so forest coverage 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, making 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 projects as timely as possible.
