May 6, 2008

Gobi DesertThe Green Wall of China or Green Great Wall is a project to plant 2,800 miles of forest strips across the northwest rim of China skirting the Gobi Desert. It is consider one of the biggest ecological projects in history. The project will take 73-years of forestation and will cost 96.2 billion over the next decade.

The Director of the State Administration of Forestry, Zhou Shenxian, said “The project will greatly reduce the sandstorm thread to Beijing, upon completion.” The Gobi Desert has been taking grassland over the year, which is a great threat to China agriculture economy.
