Twenty people have done the unimaginable task of clearing the world's highest peak of rubbish left behind by climbers.
Namgyal Sherpa, the leader of the Extreme Everest Expedition 2010, took his group above the 8,000-metre mark to collect empty oxygen bottles, gas canisters, torn tents, ropes and utensils, Sky News reports.epal Tourism officials have released a video of the trash collection, which has been gathering on the mountain for decades.
Since 1953, over 4,000 adventurers have scaled the peak, and most of them have left behind their used gear and rubbish before descending due to exhaustion and lack of oxygen.
"Collecting the rubbish is quite a risky task. Such tasks cannot be carried out by anybody," Sky News quoted Namgyal, as saying.
After a dangerous 40-day campaign, the waste brought back to base camp was expected to weigh around 2,000kg.
The team was not only concerned with the impact of garbage on Mt. Everest, but also with the threat of global warming.
"We used to climb over snow. These days we climb over rocks. If it continues this way succeeding generations will only be able to read in books that there was once snow in the Himalayas," Namgyal said.
