If you take a shit on Everest, then because of the cold, the turd will not disintegrate and will not go anywhere, but will remain in place. And since there have always been a lot of climbers on the mountain, it is thickly covered with shit. This is fraught with big problems. For example, with warming, the ice crust will melt and the shit will flow down. The element can even take the form of a shit avalanche. Fortunately, since 2014, there has been a strict rule for all conquerors of Mount Everest: take a shit, put it in a bag and take it with you.
