Mountain climbers around the world dream about going up Qomolangma, the highest mountain in the world. But many people who have climbed the mountain have left waste material that is harming the environment.
A team of Americans is planning the largest clean-up effort ever on Qomolangma. They will make the risky trip up the mountain next month.
The team of eight Americans will be guided by more than twenty Sherpas of Nepal（尼泊尔夏尔巴人）. Their goal is to remove all the rubbish they see. They will spend two months cleaning up the mountain by gathering oxygen bottles, fuel containers, batteries, drink cans, human waste and all kinds of disposable products（一次性产品）. They are expected to remove at least three tons of rubbish in large bags.
Team leader Robert Hoffman is making his fourth trip up the mountain. He says he hopes to bring Qomolangma to the condition it was in before the first successful climb fifty years ago. He says he hopes the effort will influence other people to clean up the environment closer home.
Disposable products on Qomolangma are a major concern. So the clean-up team will take along newly developed equipment to collect and treat disposable products. Over the years, the disposable products have polluted the mountain. In the warm season when the ice melts, the polluted water flows to Nepali villages below. The problem has gotten worse in recent years because climbing Qomolangma has become more popular.
