BEIJING (Reuters) - China has retrieved 8.5 tonnes of waste from Mount Everest since April as it clears garbage left by growing numbers of visitors, the state-run Global Times said on Thursday. 
  
 Enthusiasts from all over the world who flock to the world’s tallest mountain, at a height of 8,850 meters (29,035 ft) between Tibet and Nepal, discard tonnes of trash each year. 
  
 A team of 30 people has cleared about 5.2 tonnes of household waste, 2.3 tonnes of human faeces, and one tonne of mountaineering trash in the cleanup by Tibetan mountaineering officials, the paper said. 
  
 The work is almost as demanding as tackling the summit, say climbers, since collection is a strenuous task that boosts the consumption of oxygen people need to breathe, it added. 
  
 During last year’s climbing season, which usually runs from March until May, 202 climbers summitted from the Tibetan side, versus 446 from the Nepali side, while thousands of tourists visited base camps on both sides. 
  
 The warming global climate has melted frozen garbage left by climbers over decades, spurring environmental concern in Nepal, India and China, which is taking tough measures to clean up air, water and soil contaminated after decades of breakneck growth. 
  
 Since 2015, officials in Tibet have given every climber two trash bags to retrieve at least 8 kg of rubbish, levying a fine of $100 for each kilogram by which a climber falls short. Nepal adopted similar rules in 2014. 
  
 China also plans to build environmentally friendly toilet and waste collection sites at Mount Everest, the official Xinhua news agency said. 
  
 Authorities in Tibet have pledged to complete 45 pollution cleanup tasks before 2020, according to a list published this week by the environment ministry, after a central inspection team flagged concerns last year. 
  
 Beijing plans a further round of inspections early next year, the People’s Daily newspaper of the ruling Communist Party has said. ||||| Veteran Climber Kami Rita Sherpa, center left, receives an honorary certificate during a function organized to mark Everest Day in Kathmandu, Nepal, Tuesday, May 29, 2018.

 KATHMANDU, Nepal (AP) — Nepal honored several Sherpa guides for their Everest successes on the anniversary Tuesday of the first conquest of the world's highest peak. 
  
 Government minister Bina Magar, herself an Everest climber, honored the guides at a ceremony held every year on the date in 1953 that New Zealander Edmund Hillary and his guide Tenzing Norgay first set foot on the summit of the 8,850-meter (29,035-foot) mountain. 
  
 Those honored included Kami Rita, who just climbed the mountain for a record 22nd time. He said last week when he returned from the mountain that he plans to guide climbers to the summit next year as well. He first scaled Everest at age 24 and has made the climb almost every year since then. 
  
 The ceremony also honored Lhakpa Sherpa, 44, whose nine climbs are the most for a woman. She lives in West Hartford, Connecticut, for much of the year and works at a grocery store when she's not guiding foreign climbers. She and her brother guided some 50 climbers on Everest earlier this month. 
  
 The ceremony also honored seven brothers who all have made it to the top of Everest and have combined for 61 total ascents. 
  
 A certificate issued by Guinness World Records was handed over to the brothers at the ceremony in Kathmandu. 
  
 Since Mount Everest was first conquered, thousands of climbers have reached the summit, while more than 300 have lost their lives on the unpredictable slopes. 
  
 An avalanche struck just above base camp in 2014, killing 16 Sherpa guides, while a year later another avalanche triggered by an earthquake ripped through base camp, killing 19 people. |||||

The world's tallest mountain is covered in a whole heap of trash. That's why a Chinese team of 30 people has been tasked with hauling decades worth of climbers' garbage off Mt. Everest. Since April, they've managed to bring down over 9 tons of cast-off mountaineering gear and other garbage, the Reuters reports, citing the state-run Global Times. However, lost carabiners and old tents don't make up all the junk. Human waste and household waste made up over two tons and five tons of the removed mass respectively. Since the task is an extremely arduous one, officials in Tibet have given every climber since 2015 on Tibet's side of the 29,000 foot peak two trash bags to use to bring back down at least 8 kilos of trash, or over 17.5 pounds. A climber is fined if they come up short. Scientists say climate change is warming things up on Everest, causing snow to melt and accumulated trash to emerge. At the same time, more brave climbers than ever are ascending the mountain. Per Reuters, last years climbing season saw 202 summit from the Tibet side and 446 via Nepal's slope. Thousands of others visited camps along both mountainsides. According to the AP, the spring season runs just March until the end of May, after which weather conditions on the mountain begin to deteriorate. There are only about a couple of days of windows of good weather on the highest part of the peak in May, when climbers rush to attempt their way to the summit. (Among this year's climbers to reach the top was double amputee Xia Boyu.)
