China requires Everest climbers to carry their waste out with them
The Mount Everest base camp in Tibet will be closed to all tourists until further notice – in order to fight sky-high litterbugs. The base camps of the world’s highest mountain – one on the Nepalese side, one on the Chinese – are popular tourist destinations in their own right. But now tourists have been indefinitely blocked from visiting the Tibetan camp (the Nepalese camp remains open).  Only people with climbing permits will be allowed to ascend to the Tibetan base camp, at an altitude of 17,000 feet.
