Sandstorms due to humans
|
A recent study of the sources of sandstorms suggests that a major reason for the worsening of sandstorms is environmental destruction at the hands of humans.
According to experts, this year's sandstorms have been more frequent and destructive. Through field investigations, experts found that while the formation and the strength of sandstorms are directly related to wind power, temperature, precipitation and conditions of earth surface, human destruction of the natural environment, including deforestation and the spread of deserts, are the major causes.
Qu Jianjun, a researcher specializing in desertification, pointed out that vegetation in arid regions is very hard to restore after being destroyed. "And excessive grazing and deforestation have led to the spread of deserts which are the sources of sandstorms," he said.
The study was recently carried out by experts with the State Environmental Protection Administration and the Chinese Academy of Sciences, and was the first scientific investigation of the phenomena ever undertaken in China.
