Ken Noguchi, who in 1999 became the youngest person to climb the highest peaks on the world's seven continents, is returning to the last mountain he conquered -- Mount Everest.
But when the 27-year-old leaves this month it will be in search of something far less glamorous than records: garbage.
The trip is a continuation of a campaign to collect garbage that he began last year that saw 36 people recover 1.5 tons of debris from the mountain. This year's expedition will include nearly 40 members from South Korea, China, Nepal and Georgia.
