Mount Everest is the world's highest mountain. Climbers are leaving a lot of poo on the slopes. A local said the mountain now stinks. He added that he can see poo on rocks, and some climbers are getting sick. Climbers must now buy a "poop bag" for their poo. They throw it away when they come down from the mountain.

The problem of waste on Everest is growing. Climbers leave camping equipment and cans of oxygen there. There may also be over three tons of human poo. Most of this freezes. It does not degrade. The poop bags will help to keep Everest cleaner. They will be good for the health of climbers and the mountain.
