Nearly 9,000 meters above sea level and dangerous to reach, Mount Everest would seem a likely place to be free of litter and waste. However, you may be surprised to know that climbers over the past 50 years have left a staggering 50 tons of trash and debris and human waste along the summit. This has prompted the world’s most experienced sherpa to join forces with the Eco Everest expedition for his 19th ascent of Mount Everest, this time not for a climbing expedition, but rather for a conservation expedition. Apa Sherpa and company left today on their journey and will use this trip to highlight the devastating effects of the global climate crisis on Mount Everest, where global warming is causing the snow at the summits to melt at a rapid rate. Along the way, they plan on filling hundreds of rubbish sacks with human waste and litter left behind by previous climbers.
