The commercialization of Mount Everest has destroyed the environment and communities in the Khumbu region. The vast majority of inexperienced climbers leave trash in the mountains. Polluting factories due to modernization have not only destroyed the environment but also destroyed the economy of the Khumbu region. At 8,848 meters above sea level, Mount Everest is the highest trash can in the world. The atmospheric pressure at this altitude is only thirty-three percent of the pressure at sea level. For this reason, almost all climbers bring oxygen tanks. Typically these weigh around eight pounds each. These oxygen tanks run out of oxygen and climbers throw them away to lighten their load a little. Inexperienced climbers have been known to throw equipment down the mountain, including oxygen tanks, tents, ropes, human waste, and sometimes dead bodies. There are legitimate cases where abandoning gear is vital to survival. There are now mountain expeditions whose sole purpose is to collect debris left behind. The use of oxygen also gives a false sense of security to inexperienced climbers. The use of oxygen prevents them from really knowing what Everest looks like. Inexperienced climbers think they can acclimatize faster and climb faster because they have oxygen they wouldn't otherwise have. They become more confident in their abilities and often make mistakes because of it. The book “Into Thin Air” was about a 1996 expedition led by Rob Hall, with author Jon Krakauer as his client. Jon described how miscalculations and miscommunications about the amount of oxygen present in the mountain caused the deaths of fifteen people. To counter this argument, experienced climbers know they need oxygen because I...... middle of article .......wikipedia.org/wiki/Edmund_Hillary>."Everest: physiological effects."
