China is rebuilding the Great Wall of China. However, now they build not with stones, mortar, sand and rubble, designed to stop the enemy hordes. Nowadays they build with trees. Just like the wall erected many years ago, the world's largest man-made forest should stop the enemy that China has been fighting for many years and which is no less dangerous than the problem of overpopulation. This enemy is the desert that occupies most of eastern China and continues to grow non-stop.
