Climbing Mount Everest is no longer the challenge it used to be, climbing experts are protesting. Since Edmund Hillary and Tenzing Norgay reached the summit of the world's tallest mountain in 1953, the number of people attempting to scale it has exploded, at times bringing its slopes to a virtual standstill. The BBC reports that there were just eight successful ascents in 1983, but during one day in 2012, Everest saw an incredible 234 people reach its peak. Just over a week ago, British explorer Daniel Hughes became the first person to make a video call from the summit. Experienced climbers worry that the use of Sherpa guides and fixed ropes is devaluing the sport, as expeditions use weather forecasting technology to perfectly time their climb — resulting in high-altitude traffic jams like the one shown in the image above.
