The people who set out to climb Everest spend months dreaming about reaching the summit. They pay $65,000 in fees to the Nepali government; they train, trek for days, endure extreme discomfort, even danger. So it should be a simple thing to get them to pick up after themselves. Apparently not.
Nearly 60 years after Edmund Hillary conquered Everest, and 30 years after climbing turned commercial, the region is still struggling to deal with mass tourism.
