Climbers will now have to purchase special bags for the needs at the base camp and upon their return inspectors will check that they are full. The climbers produce around 250 grams of feces per day, when most of them are about two weeks into climbing the peaks.
The higher you climb, the less snow covers the ground, and in some places there is no choice but to defecate in the open. About 8,000 biodegradable excrement bags have now been purchased from the US to be used by the upcoming climbing season.
