FILE – In this May 26, 2003 file photo, the 8,850-meter (29,035-foot) Mount Everest is seen from above Everest Base Camp, Nepal. The Everest climbing season began March 2014, with new rules that require climbers to bring down at least eight kilograms (17.6 pounds) of their personal garbage, and more security officials at the mountain's base camp to help climbers. More than 4,000 climbers have scaled the summit since it was conquered in 1953 by Edmund Hillary and his Sherpa guide Tenzing Norgay. Over the years, climbers have left tons of garbage on the slopes on the mountain, and some have called it the "world's highest garbage dump." (AP Photo/Gurinder Osan, File)
