At 8, 844, 43 meters high, Mount Qomolangma is the tallest mountain on Earth. While it is famous for its beautiful views, parts of the mountain are facing a problem: rubbish. Every year, thousands of visitors throw away tons of rubbish, such as bottles and plastic bags.

According to the UN, over 140 tons of rubbish has been left on the mountain. To reduce rubbish, China is limiting(限制) the number of people who are allowed to climb up the north side of the mountain. Only 300 people will be allowed to climb it, and only during spring.

Local people cleaned the mountain last year, removing rubbish at a height of 5,200 meters. They collected about 8.4 metric tons(公吨) of rubbish。

This year, the local government plans to spend 4 million yuan on a new clean-up activity. The local government is also setting up stations to sort(分类), recycle and break down rubbish collected from the mountain. A group of artists will also try to turn the rubbish into art works. They will show these works of art to remind people not to leave rubbish when climbing the mountain.
