World's highest ever clean-up campaign successfully completed

Twenty Nepali climbers have returned from an expedition to remove some of the rubbish left by climbers on Mountain Everest in the world's highest ever clean-up campaign.Many Nepali and foreign climbers have cleaned Mount Everest in the past but Namgyal Sherpa, leader of the Extreme Everest Expedition 2010, said no one had dared to clean above 8,000 meters (26,246 feet), an area known as the death zone for the lack of oxygen and treacherous terrain.Namgyal and his team of seasoned climbers, carrying empty rucksacks and special bags, risked the zone's thin air and freezing temperatures to pick empty oxygen bottles, gas canisters, torn tents, ropes, and utensils lying between the South Col and the 8,850 meter (29,035 feet) summit.
