One of Mount Everest's top guides has expressed concern over the growing piles of rubbish at the summit as he was honored by his government to mark Everest Day.
Sherpa guide Kami Rita, who has climbed Mount Everest 30 times, was honored in Kathmandu by Nepalese Prime Minister Pushpa Kamal Dahal on the anniversary of the first successful summit of New Zealander Edmund Hillary and Nepalese Sherpa Tenzing Norgay in 1953.
