Everest climbers they will have to take their excrement with them as Nepal tries to tackle its growing waste problem.

Those hoping to climb Everest this year will need to make some minor adjustments to their must-have list.

New rules now require climbers to carry their faeces down from the world’s highest peak, in a bid by Nepal to tackle rising pollution.

Most people who attempt to climb the 8,849-meter (29,032-foot) Everest do so via Nepal, paying $11,000 each just for the climbing permit.

With gear, food, supplemental oxygen, guides and more, the climb costs over $35,000.

But the world’s highest peak has a human poo problem, CCN reports, due to the number of visitors and harsh conditions on the mountain.

“The problem of human waste on Everest is very big,” Divas Pokhrel, first vice president of the Everest Summit Association, told CNN, adding that at the highest points of the mountain, “it pollutes the mountain environment.”

Nepal requires all Everest climbers to use tracking chips.

Without the new rules, the problem with human excrement was very likely to get worse: Last year, Nepal issued a record 478 climbing permits to climb the summit. Twelve climbers have been confirmed dead on the mountain, while another five remain officially missing.

Jinesh Sindurakar of the Nepal Mountaineering Association told CNN it is estimated that 1,200 people will be on Everest this season.

“Each person produces 250 grams of feces per day and they will spend 2 weeks in the higher camps for the summit push,” Sindurakar explained, adding that each climber will be given two bags of faeces, which can be used six. times.

The bags contain chemicals to solidify human waste and make it odorless, Sindurakar said, and the Khumbu Pasanglhamu municipality of Nepal will issue around 8,000 bags this season.

Efforts to reduce the impact of tourism in the Himalayas have intensified, with 35,708 kilograms of waste and plastic being removed from peaks such as Everest, Loche, Annapurna and Barunche through an initiative by the Nepalese Army, according to the Himalayan Times.
