Cleaning Up Mount Everest
Ken Noguchi is a mountaineer who is slowly cleaning up Mount Everest. During his campaign, which has now taken him on five trips up the mountain, he has brought back an estimated 9,000kg of rubbish.
He recently completed another trip, where he brought a further 500kg down. Some estimates place the amount of rubbish on Everest at 50 tonnes, so he has his work cut out for him. :: The Guardian
