Danxia landform damaged by tourists

An online video showed several people broke into the Danxia landform special protection zone at Zhangye in Gansu province, contaminating the biology of the terrain with their footprints. The landform is actually layers of different colored sandstone and minerals that were pressed together over a period of 24 million years and then buckled up by tectonic plates.
