Climbers will now have to carry their excrement back down to base camp in a plastic bag. “We have received complaints that human feces are visible on the rocks and some climbers are falling ill,” said Mingma Sherpa.

At base camp, toilets are available in special tents inside which barrels, intended to collect stools, are emptied. But higher in altitude, in the higher camps, climbers most of the time improvise their toilet by digging a hole in the snow or on the ground.
