Paragraph 1
There is a new
about going to the toilet on Mount Everest. People climbing the world's highest
will now have to take their own poo back to Base Camp. There has been an
in the number of climbers on the mountain. This has led to a
of human waste being left on the
. Mingma Sherpa, a local
, told the BBC: "Our mountains have begun to stink." He added: "We are getting
that human stools are visible on rocks, and some climbers are falling
. This is not acceptable. It damages our image." The new rule requires climbers to buy a bio-degradable "poop bag". They can dispose of the bag and its
when they come down from the mountain. It will be "checked" by
there.
