Now, municipal officials responsible for Mount Everest are taking concrete steps to address this pressing issue, starting with a crucial aspect: human waste management. Previously, Everest climbers often disposed of their waste openly, resulting in unsightly scenes of human stool scattered across nearby rocks. However, there's a new protocol in place: climbers must now use "poo bags" to collect their waste and return them to base camp for proper disposal.
"Our mountains have begun to stink," Mingma Sherpa, chairman of Pasang Lhamu rural municipality, told the BBC.
The municipality, which covers most of the Everest region, has introduced the new rule as part of wider measures being implemented.
Due to extreme temperatures, excrement left on Everest does not fully degrade.
"We are getting complaints that human stools are visible on rocks and some climbers are falling sick. This is not acceptable and erodes our image," Mr Mingma adds.
Climbers attempting Mount Everest, the world's highest peak, and nearby Mount Lhotse will be ordered to buy so-called poo bags at base camp, which will be "checked upon their return".
During climbing season mountaineers spend most of their time at base camp acclimatising to the altitude, where separate tents are erected as toilets, with barrels underneath collecting the excrement.
But once they begin their treacherous journey things get more difficult.
Most climbers and support staff tend to dig a hole but the higher you go up the mountain, some locations have less snow, so you have to go to the toilet out in the open.
