China Plants Trees To Hold Back Desertification

Seven years ago, with the desert creeping south at the rate of 3 km (2 miles) a year and the dust storms getting worse, the Chinese government decided to act and the solution was typical of a country where the Great Wall stands as the ultimate grand project.
It began building a “Green Great Wall”, a 700-km (435 mile) barrier of trees and enclosed grassland which will stretch across Inner Mongolia, Hebei and Shanxi provinces by 2010.
