Government in Tibet have denied the permanent(永久的) closure of Mount Qomolangma National Nature Reserve.

The announcement came after a report went viral online claiming the base camp of the world's highest mountain was “permanently closed due to heavy pollution” and caused a universal misunderstanding.

Mount Qomolangma National Nature Reserve was set up in 1988. Covering an area of more than 33, 800 square km, it is home to one of the world's most weak ecosystems(生态系统).

Kelsang, deputy director of the reserves administration, said ordinary tourists are allowed to visit areas around Rongpo Monastery, almost 5,000 meters above sea level. As for travelers who have a climbing permit, they can go to the base camp at an altitude of 5,200 meters. The mountaineering activities have been permitted by the regional forestry department.

To conserve the environment surrounding Mount Qomolangma, China carried out three major clean-ups at an altitude of 5, 200 meters and above last spring, collecting eight tonnes of household wastes, human wastes and mountaineering trash. This year, the clean-up will continue, and the remains of mountaineering victims(受害者) above 8,000 meters will be centrally dealt   with for the first time. Meanwhile, the number of people who stay at the base camp will be kept under 300.

Recently, there are 85 wildlife protectors in the reserve, and 1,000 herders have part-time jobs going around and cleaning up garbage.

These measures aim to strike a balance between various demands such as environmental protection, local poverty relief, mountaineering and education, said Wang Shen, county chief of Dingri at the mountain foot.

At the end of the year, it designs events to help children celebrate Christmas without increasing the amount of waste they create. Hanna Seligmann works for the foundation. “So let’s figure out what is in our bag of trash.” She shows adults and children how to reduce waste during the holiday gift-giving season. “You can sort it as a cardboard item or you can sort it as a plastic item.” “We encourage using things that are already in your house like newspaper, old magazines, using a gift within a gift.” Urging people to recycle is important in the Washington, D.C., area, because Potomac River, one of the most famous rivers in the country lies there.

“Over time we realized that really just doing trash cleanups was the symptom of the problem, not getting to the root cause. And so it was just a little over a decade ago that we started the initiative (倡议) itself.” says Seligman.

The Trash Free Potomac Watershed Initiative is an effort by the Alice Ferguson Foundation to support clean agricultural methods. It includes educational programs teaching children about the kinds of pollution that can enter the watershed.

One activity is called the Trash Timeline Game. It teaches children that the things they throw away do not decompose, at the same rate. For example, paper dissolves in about four weeks. An apple core may take two months to rot. A metal can take up to 100 years.

Many Beijing residents go to great lengths to avoid breathing the city's smoggy air, especially when it reaches critical pollution levels, but one local entrepreneur decided that canning(灌装) and selling this poor quality air as a souvenir would be a great idea. Believe it or not, he was right.

After seeing a number of companies achieve commercial success by canning fresh air from countries like France, Canada or Australia and selling it in China, Dominic Johnson-Hill, a British-born citizen of Beijing and owner of the Plastered 8 souvenir shop, decided to turn the idea on its head and sell canned Beijing air throughout China and abroad.

"I'd seen people going crazy to buy canned air from Canada and Australia, so I thought it was time to push business the other way," the entrepreneur said. "They' re perfect gifts! What else are you going to take home when you go home from Beijing? A roast duck? A Plastered T-shirt? These cans are light, portable, you can just imagine someone' s face when they unwrap (打开) it for Christmas."

The few mouth-fulls of Beijing air come in standard tin cans featuring a couple of iconic city landmarks as well as a bitter description of the contents: "a unique mix of nitrogen, oxygen and some other stuff". The ironic (讽刺的) souvenirs cost 28 RMB (US $4) and are available at the Plastered 8 shop, as well as on its online shop. But if you're actually considering buying some, you'd better ask shop in advance, as they are virtually flying off the shelves. Johnson-Hill said that his shop is selling hundreds of Beijing air cans every day.

Personally, the well-sold can probably is an awakening for the public to be concerned about the living conditions. Yet one thing that’ s not particularly clear is whether the air is really collected from Beijing, as the cans are labeled as "Made in Shenzhen". There's a big chance that' s just a kind of Plastered 8 humor, as they also list "Choking Hazard" and "May have unidentified objects inside." as warnings.

Anyway, it is probably a unique way to arouse public awareness of protecting the environment.
