Most climbers to Qomolangma used to start their climbing in Nepal, on the mountain's south side. But in the last few years, the route(路线) from China has become more popular. It then brings a lot of environmental problems to the north side. In June, 2017, Chinese government said it would close Qomolangma from climbing from the north side for the coming autumn season as it took time to clear out the rubbish on the mountain and make better protection of it.
However, the number of climbers has still been rising since it was opened again. Qomolangma, one of the most popular and dangerous challenges for mountain climbers, is now in a terrible mess. Among all the 100 million visitors, around 60,000 climbers visit the Chinese side of the mountain each year. Qomolangma has become the world's highest rubbish dump(垃圾场) thanks to their visits.
To protect the mountain, the Chinese government told the whole world that China would limit the number of visitors to Qomolangma. A clean-up began from February 5th, 2018 and the number of visitors to the north side should not be more than 300 every year from that day on.
There are still more places that are "hurt" by human activities like Qomolangma. What humans should think about may not be what Earth can do for us, but what we can do for our mother planet. Can you imagine what our blue planet will be like in 100 or even 1,000 years if things do not change?
