'Everest has become cash-cow for Nepalese government'
Sherpa Tenzing Norgay's son has claimed that Mount Everest has become a cash-cow for the Nepalese government and the overcrowded peak is now strewn with rubbish.
Norbu Tenzing says his famous Sherpa father would be saddened that the mountain has become something of a tourist attraction, with hundreds of climbers attempting to tackle the world's highest peak.
