Nepalese Kami Rita Sherpa reached the summit of Everest on Wednesday morning for the 23rd time, breaking the record for the number of climbs on the roof of the world he had established a year ago, the organizer said. of this expedition. A professional guide for more than two decades, Kami Rita climbed to the top of the mountain in 1994 for the first time at 8,848 meters, "I have never climbed for records, I was just working. Before, I did not even know that there were records to be set, "said a 49-year-old mountain climber a month ago, who has already climbed other" 8,000 "as the second highest mountain in the world, the K2. With his 22nd climb last year, he had already broken the record he shared with two other Sherpas. The Sherpas are the backbone of the Himalayan industry in Nepal, a mountain people whose name has become commonplace in terms of a porter or mountaineering guide. They are known for their physical abilities to evolve at very high altitude, where the breathing becomes more and more difficult. Their acclimatized body uses oxygen more effectively than that of the plains inhabitants, according to a British scientific study. This season, Nepal has delivered a record 378 permits for the ascent of Everest. Each permit costs $ 11,000. This is fearing new traffic jams on the roof of the world. Each holder of a permit being accompanied by a guide, this means that about 750 people will start on the same track in a few weeks. At least 140 more are preparing to attack the north face of Everest from Tibet, according to expedition organizers. The number of people at the summit this year could exceed that of last year (807). Five people died in 2018 during the ascent. Everest was first climbed in 1953 by New Zealander Edmund Hillary and Nepalese Tenzing Norgay. But democratization did not occur until much later. And some fear that the number of climbers on the slopes of Everest is not sustainable, on the one hand for security reasons, and on the other because of the pollution they generate and litter that accumulate.
