The problem of garbage disposal -- a nagging issue common to major cities around the globe -- has grown so large that even the world's most lofty place is not immune to litter anymore, mountaineer Ken Noguchi laments.

The 27-year-old climber, who in 1999 became the youngest man to have scaled the tallest peaks of the world's seven continents, said 8,848-meter Mount Everest suffers serious garbage pollution.

He is one of the organizers of ACTIONS 8848, an exhibition of garbage retrieved from "the world's highest dump site."
