Mount Everest, the world's tallest mountain, has become a dumping ground for human waste and garbage, with plastic pollution and human waste posing serious threats to the fragile ecosystem of the region. The surge in tourism has led to a significant increase in pollution, with climbers leaving behind trash, empty oxygen bottles, steel bowls, spoons, sanitation pads, and cut-off logos and tents. Microplastics, likely from climbing gear, have also been found in snow and water samples, while sewage from septic tanks at lodges in the national park leaks and further pollutes the groundwater. While cleanup efforts are underway, waste management rules are not well-enforced, and the problem of pollution on Mount Everest persists.

What You'll Learn
The commercialisation of mountaineering
Mount Everest, located in the Mahalangur Himal sub-range of the Himalayas in Nepal, is the world's highest mountain, reaching an elevation of 8,848 to 8,850 meters above sea level. Once a challenging pursuit reserved for experienced mountaineers, climbing Everest has become increasingly commercialised, with climbers paying expedition fees ranging from $32,000 to $200,000 for a chance to reach the summit. This commercialisation has made the climb more accessible to inexperienced adventurers, leading to a record number of climbers and a surge in tourism to the region.
However, the surge in tourism has led to significant pollution and waste management issues. The mountain and its surrounding areas have become littered with human waste, leftover meals, beer and fuel cans, and other garbage. Microplastics, likely from climbers' clothing and equipment, have been found in snow and stream water samples, highlighting the human impact on the region's fragile ecosystem. The lack of enforced waste-management rules on Everest exacerbates the problem, with visiting climbers often lacking the energy or motivation to bring their trash back down the mountain.
To address the waste crisis, various organisations are taking initiatives. The Nepali government frequently deploys its army for cleanup expeditions, and in collaboration with non-governmental organisations, they have collected significant amounts of waste from Everest and other mountains. The Sagarmatha Pollution Control Committee (SPCC) promotes environmental sustainability through waste management infrastructure development and educates local communities on reducing, reusing, and recycling. Additionally, the Mount Everest Biogas Project is constructing a solar-powered biogas system powered by human waste to provide sustainable fuel for local communities.

The surge in tourism
Mount Everest, the world's tallest mountain, has seen a surge in tourism in recent years. Edmund Hillary and Tenzing Norgay became the first people to reach the summit in 1953. Since then, thousands of adventurers have attempted to follow in their footsteps. In 1979, 3,600 people went on expeditions to the mountain, while in 2019, this number rose to over 58,000. The commercialisation of mountaineering has made it more accessible, with climbers paying fees ranging from $32,000 to $200,000 to attempt the summit. This has led to a record number of climbers, with 463 permits issued in 2023.
The increase in tourism has had a significant impact on the region, particularly regarding pollution. Everest is fast becoming the world's highest dumping ground, with a large amount of waste accumulating on the mountain. This includes human waste, leftover camping meals, beer and fuel cans, and microplastics from clothing and equipment. The surge in tourism has also resulted in increased waste from climbers, such as empty oxygen bottles, steel bowls, spoons, sanitation pads, and cut-off logos and tents from various companies. The base camp, which is dotted with tents, has been described as the "dirtiest camp" by trekking guides, who have called for stricter rules and more effective cleaning campaigns.
The Nepali government has recognised the waste problem and frequently mobilises its army for clean-up expeditions. In 2019, the Nepali army collected over two tonnes of waste, and in 2023, they collected 35 tonnes of waste from four mountains, including Everest. Several non-governmental organisations and private companies are also leading and organising clean-up campaigns and educating climbers and local communities on waste management. One such organisation is the Sagarmatha Pollution Control Committee (SPCC), which promotes environmental sustainability and educates the local community on reducing, reusing, and recycling. The Mount Everest Biogas Project is another initiative that aims to tackle the human waste crisis by building a solar-powered biogas system powered by human waste to supply local communities with sustainable fuel.
While these efforts are commendable, waste management rules are not well-enforced, and the current practices are not enough to address the scale of the problem. There is a need for stronger regulatory measures for Everest expeditions, including controlling the flow of expedition traffic and enforcing environmental protection. Additionally, there should be a focus on developing sustainable solutions and promoting responsible tourism and sustainable practices among climbers to mitigate the impact on the fragile ecosystem of the region.

Human waste
Mount Everest, the world's highest mountain, has become increasingly polluted due to growing tourism and a lack of solid waste management systems. Among the various forms of pollution, human waste is a significant issue.
The surge in the number of tourists and mountaineers visiting the Sagarmatha National Park, where Mount Everest is located, has resulted in a substantial amount of human waste being left on the mountain. In 2021, a Reddit post went viral, highlighting that Mount Everest is covered in waste, including an estimated 26,500 lbs of human excrement. This waste is not limited to the base camps but can also be found along climbing routes and even near the summit.
The human waste problem on Mount Everest is exacerbated by the lack of proper waste management infrastructure. While the Sagarmatha Pollution Control Committee (SPCC), a non-profit and non-governmental organisation, works to keep the Khumbu region clean, their efforts are limited. They have installed trash containers along trails and provide door-to-door garbage collection in larger villages. However, waste management rules are not well-enforced, and the SPCC's capacity is insufficient to address the sheer volume of waste generated by climbers and expeditions.
Local climbers are sometimes hired to bring human waste down from base camps in barrels, which is then dumped into pits. However, this waste often washes downstream during the monsoon season, contaminating water sources. Additionally, the waste is not completely filtered from the water supply, leading to intestinal problems among visitors and contributing to the overall human waste issue.
The Mount Everest Biogas Project aims to address the human waste crisis by constructing a solar-powered biogas system powered by human waste to supply energy to local communities. This initiative is one of several efforts by non-governmental organisations and private companies to promote sustainable waste management practices and educate climbers and local communities on the importance of responsible waste disposal.
While the human waste pollution on Mount Everest is a pressing issue, it is not insurmountable. Through stricter regulations, more effective cleaning campaigns, and the implementation of sustainable waste management solutions, it is possible to mitigate the impact of human waste on the fragile ecosystem of the world's highest mountain.

Microplastics in snow and water
Mount Everest, the tallest mountain on Earth, has been described as "the world's highest garbage dump". The mountain has attracted a lot of tourists and climbers over the years, leading to a significant amount of waste accumulation. This waste includes human waste, leftover meals, beer and fuel cans, and human poo.
The issue of waste on Mount Everest is so severe that it has led to the mountain being described as a "garbage dump". The growing popularity of Mount Everest as a tourist destination has resulted in various forms of pollution, spoiling the fragile ecosystem of the region. The exponential rise in tourism has led to significant issues, particularly pollution. This has resulted in the contamination of the mountain's snow and water with microplastics.
Microplastics are plastic shreds smaller than 5 millimetres that come from bags, bottles, and other items that have broken down into pieces. In 2019, an interdisciplinary team of more than thirty scientists collected hundreds of samples of rock, water, snow, and ice from Mount Everest. The samples were analysed for the presence of microplastics, and the results revealed that all 11 snow samples from Everest contained microplastics. Three out of eight stream water samples also tested positive for microplastics. The highest concentration of microplastics was discovered in a snow sample from 8,440 meters above sea level, with a concentration of ~30 MP L−1. Stream water samples from the same location contained ~1 MP L−1.
The microplastics found in the snow and water of Mount Everest likely come from climbers' equipment and clothing. The plastic pieces are mostly polyester fibres, which are common in outdoor clothing. The presence of microplastics in Mount Everest's snow and water highlights the human impact on the environment, even in the most remote and extreme locations. It is important to address this issue through the development of more sustainable materials for clothing and equipment, as well as improved waste management practices.

Lack of waste management infrastructure
Mount Everest, the world's tallest mountain, has become a dumping ground for human waste and garbage, with climbers leaving behind an alarming amount of trash, including plastic pollution. The surge in tourism has resulted in a significant increase in pollution, as climbers leave behind empty oxygen bottles, steel bowls, spoons, sanitation pads, cut-off logos, and tents.
The lack of adequate waste management infrastructure has exacerbated the problem. While the Sagarmatha Pollution Control Committee (SPCC), a local non-governmental organization, has been working to address the issue, their efforts are limited, and waste management rules are not effectively enforced. The SPCC was created by local Sherpa people in 1991 and focuses on litter control and periodic base camp clean-up campaigns. However, the trash problem on Everest persists, with climbers often lacking the energy or motivation to bring their waste back down the mountain.
The Nepali government has also mobilized its army for clean-up expeditions, collecting several tonnes of waste from Everest and other mountains in the region. Additionally, the Mount Everest Biogas Project is working to build a solar-powered biogas system that uses human waste to supply local communities with sustainable fuel.
Despite these efforts, the lack of waste management infrastructure remains a pressing issue. The regulatory measures for Everest expeditions fall short compared to other countries, and the trash problem continues to worsen. The commercialization of mountaineering has made it easier for climbers to pay fees and attempt the summit without adequate preparation or concern for waste management.
Everest's pollution problem extends beyond the base camp, with microplastics and PFAS chemicals found in water and snow samples. These substances pose health risks to both transient climbers and local communities in nearby settlements. The septic tanks at many lodges in the national park leak, further polluting the groundwater. As a result, there is a growing need for sustainable solutions and stricter regulations to address the lack of waste management infrastructure on Mount Everest.
