There is  new rule about going to  toilet on Mount Everest. People climbing  world's highest peak will now have to take their own poo back to Base Camp. There has been  increase in the number of climbers on  mountain. This has led to  problem of human waste being left on the slopes. Mingma Sherpa,  local official, told the BBC: "Our mountains have begun to stink." He added: "We are getting complaints that human stools are visible on rocks, and some climbers are falling sick. This is not acceptable. It damages our image." The new rule requires climbers to buy  bio-degradable "poop bag". They can dispose of  bag and its contents when they come down from  mountain. It will be "checked" by workers there.
 problem of waste, litter and pollution on Mt Everest has been growing for years. Many people leave camping equipment on  slopes. Thousands of discarded cans of oxygen litter the mountain.  environmental organization estimated that there was around three tons of human poo between Base Camp and  summit of Everest. Much of this freezes and does not degrade. The India Today website said  poop bags will help with  waste problem. It wrote: "It is hoped that this measure, along with ongoing clean-up campaigns, will help restore  dignity of this iconic peak." It added that  waste bags would, "safeguard  health of both climbers and  local environment".
