Decades of commercial mountaineering have turned Mount Everest into the world’s highest rubbish dump as an increasing number of big-spending climbers have paid little attention to the ugly footprint they leave behind. Fortunately, collective action once again proved its value. In a coordinated effort with local authorities and NGOs, the Nepalese army has managed to clean nearly two tons of non-biodegradable waste in less than a week. After the on-site cleanup campaign was finished, the collected trash, which includes discarded tents and a variety of mountaineering equipment, was sent to waste management facilities in the area where it is expected to be sorted and eventually recycled.
