Mother Earth Monday: Poo-to-Biogas Digester Saves Mt. Everest?

Maybe a biogas digester is the solution to Mount Everest’s poop problem. Nepal’s mountaineering association says  climbers leave 26,500 pounds of feces every year.  “It has a serious effect to our environment,” said Kami Diki Sherpa in a 2013 interview. “It has polluted our water source.”  One way to handle the problem would be to build an anaerobic digester in a small village near Everest’s base, and convert all that human poop to biogas, an energy source for the Sherpas.
