JUST SWEEP THOSE DESERTS UNDER A RUG OR SOMETHING

While some mad scientists work on the idea of surrounding the Earth with a million mirrors to combat global warming others are planning to build a giant wall around the Saraha desert in order to stop the desertification of Africa. The 6,000 km long barrier would be created by flooding sand dunes with bacteria which cause them to turn into sandstone in order to stop the shifting dunes and prevent the desert from further encroaching on currently habitable land. A similar plan called “The Green Wall of China” has proposed to stop the growth of the Gobi Desert in northwestern China. (BBC)
