Each season about 7,200 kilos of human waste remain in Camp IV of Everest. Local authorities have launched a new rule.
Starting this year, each climber who leaves base camp will take with him two bags of excrement. The bags hold approximately one and a half kilos. A human being generates about 250 grams of feces a day. It takes an average of two weeks to go up and down Everest, so they must make between six and seven bowel movements in each bag.
