A record number of climbing permits have been issued this year by the Nepalese government for the annual “Death Zone” ascent, which usually takes place from March to late May, perhaps even late June, weather permitting.

A second climbing season runs from September to November but is not as popular.

Every year, when the climbing season ends, the trails and the “bases” of the groups resemble a dump, from the garbage left behind by the climbers: from discarded climbing gear and tents to oxygen bottles and hundreds of plastic bags.

Sherpa Mingma Tenzi, a guide on Everest, posted a video on social media to show the world how much trash people leave on Everest.

He estimated that 200 kg of rubbish was collected at one camp station alone.

Although climbers are instructed to take their trash down the mountain, apparently this is difficult to enforce, resulting in the “Top of the World” every December resembling a vast garbage dump.
