This year, 381 climbers had set out for the Everest via the South-East ridge in Nepal. Human error, and not nature, is thus the cause of these deaths. Over 300 climbers and sherpas were en route to the Everest through the South-East ridge on May 23. Experienced sherpas of the Sagarmatha Pollution Control Committee, employed by the Nepalese government at the Everest Base Camp, are vigilant about pollution. But the vigilance is lax in the other peaks where pollution is higher than that in the Everest.
