The green wall of china to be completed in 2074.

The Green Wall of China is the greatest and biggest ecological project in the human history .Under the project about  4,480km (2,800 mile) long shelterbelt of trees will be planted across the republic of china to stop the expansion of the gobi desert.It will be completed around 2074.

So why is the green wall of china being built?

Each spring, the dust from China's northern deserts is swept up by the wind and whipped eastward, blasting into Beijing. A choking blanket of particles coats houses, cars, and people, and the city's hospitals become flooded with patients suffering from respiratory ailments. The dust clogs machinery, shutters airports, and destroys crops, forcing thousands of rural Chinese off their lands. Clouds of it blow throughout Asia, carrying pollution and potentially infectious disease. In Korea, the government recently considered declaring the dust storms a natural disaster.
The Green Wall project was begun in 1978.As of 2009 China’s planted forest covered more than 500,000 square kilometers (increasing tree cover from 12% to 18%) – the largest artificial forest in the world.However, of the 53,000 hectares planted, a quarter has died and of the remaining many are dwarf trees, which lack the capacity to protect the soil. In 2008 winter storms destroyed 10% of the new forest stock, causing the World Bank to advise China to focus more on quality rather than quantity in its stock species
