Question

   Sixty years after humans first conquered Mount Qomolangma,known as Mount Everest in the West,the rubbish and human waste left by climbers is turning the world's highest peak into the "world's highest junkyard” .

   Every year,more than 700 climbers and guides spend nearly two months on Mount Qomolangma's slopes each climbing season. They have left tons of rubbish including oxygen bottles,broken tents,ladders and wrappers,according to Ang Tshering Sherpa,chief of the Nepal Mountaineering Association.

    What's worse is that the human waste they’ve left because of the lack (缺乏) of toilets on the mountain. M Climbers usually dig holes in the snow and leave the human waste there,1' Sherpa said. "When washed down by glaciers (when the snow melts) , the human waste comes out in the open." The waste has been " piling up" for years around climbing camps,giving off an " unpleasant smell" . It has also become a health threat to people in the area since they depend on water from rivers fed by the melting glaciers,Sherpa said.

     Since 2008,Nepal has supported Eco Everest expeditions to clean the mountain each year. So far the cleaners have brought down 15 ,000 kg of trash,but they don't know how much is still left behind. Nepal has not yet come up with a plan to deal with the human waste. In 2014 the government made new rules,asking each climber to bring down 8 kg of trash — the amount a climber is expected to throw away along the route.

On the Chinese side of the mountain,the local government of Tibet is hoping to collect cleaning fees from climbers starting from this year. Chinese environmentalists have also been clearing up the mountain every year with a program called " Mount Qomolangma Action at the Third Pole of the Earth" since 2004. mf 11.
