What is happening to the Great Wall Of China?
The great wall of china has been has been and is being eroded by many natural and man-made forces. The main contributor to the damage being caused is tourists. The Great Wall Of China is an great tourist attraction, however, tourists often will recklessly break of bits of the wall taking it as a souvenir. This is causing tremendous damage. Tourists are also damaging it by simply being on it; the weight and pressure causes the wall's rocks to crack and eventually break. Gravity then moves those rocks away from the wall. This 2000 year old structure is now 30% destroyed, and if nothing changes now, it will be gone for good very soon.
