Everest's Pollution Problem: Impact And Solutions

Mount Everest, the world's tallest mountain, has faced a growing pollution problem in recent years. With a booming industry of climbing tourism in Nepal, the mountain has become a popular expedition site for hiking and climbing enthusiasts worldwide. The increase in visitors has led to various forms of pollution, including human waste, litter, and microplastics, threatening the fragile ecosystem of the region and the health of local communities. The lack of efficient waste management systems and the remote nature of the area has exacerbated the issue, leading to the contamination of the local watershed and the degradation of the natural environment.

Human waste

Mount Everest has a significant problem with human waste, which is a major contributor to the pollution of the mountain and the surrounding areas. The issue is caused by the thousands of tourists and mountaineers who visit Sagarmatha National Park each year. The human waste produced by these visitors is not properly managed, leading to contamination of the local watershed and posing serious health risks to the local communities.

The human waste problem on Mount Everest can be attributed to several factors. Firstly, there is a lack of a solid waste management system in place. While local climbers are hired to haul human waste down from the base camps in barrels, it is often disposed of in landfills near the village of Gorak Shep, which is located within the national park. This waste is then washed downstream during the summer monsoon season, contaminating the water sources for local communities.

Another factor contributing to the human waste problem is the use of biodegradable bags by some climbers. While this method is more environmentally friendly than digging holes, the bags are expensive, and not all climbers can afford them. As a result, human waste is left on the mountain, which can lead to the spread of waterborne diseases such as cholera and hepatitis A.

The increasing popularity of Mount Everest as a tourist destination has also put a strain on the local infrastructure. The number of tourists and mountaineers visiting Sagarmatha National Park has surged in recent years, with over 58,000 tourists in 2019. This has led to a lack of proper toilet facilities, as the existing facilities are unable to handle the increased volume of waste. As a result, human waste is often left on the mountain, contributing to the pollution of the area.

The human waste problem on Mount Everest has been recognised, and several organisations are working to address it. The Sagarmatha Pollution Control Committee (SPCC), a nonprofit organisation, works to keep the Khumbu region clean through controlled waste collection sites. The Mount Everest Biogas Project is another initiative that aims to redirect human waste to an anaerobic digester system, which would break down the waste and produce methane and a pathogen-reduced effluent. This system would provide a more environmentally friendly way of dealing with human waste.

Despite these efforts, the human waste problem on Mount Everest remains a significant issue. It requires a collaborative approach between governmental, non-governmental, and private organisations, as well as a focus on waste management, waste reduction, and sustainable practices to protect the fragile ecosystem of the region.

Microplastics in snow

Mount Everest, the world's tallest mountain, has been facing a pollution crisis due to the growing popularity of mountaineering and adventure tourism. Among various forms of pollution, the presence of microplastics in snow has emerged as a significant concern.

In recent years, researchers have found microplastics in snow samples collected from Mount Everest, including near the summit. These microplastics are tiny plastic pieces smaller than 5mm, mainly consisting of polyester fibres and, to a lesser extent, acrylic, nylon, and polypropylene. They likely originate from climbers' clothing and equipment, which shed small amounts of plastic fibres constantly. The highest concentration of microplastics was found at Everest Base Camp, where climbers gather to attempt the summit.

The presence of microplastics in the snow of Mount Everest highlights the far-reaching impact of human activity, even in remote and seemingly pristine environments. The increasing tourism and waste accumulation on the mountain contribute to the deposition of microplastics. With each climber generating an average of 8 kilograms of trash, the pollution is expected to rise.

The implications of microplastics in snow are concerning for the environment and the people living below Mount Everest. As the snow melts, the microplastics can contaminate water sources, posing risks to human health and local ecosystems. Additionally, the high concentration of microplastics near climbing paths underscores the need for sustainable practices in mountaineering and exploration gear.

Addressing the issue of microplastics in snow on Mount Everest requires a multi-faceted approach. It involves promoting sustainable materials in clothing and equipment design, reducing waste generation, and implementing effective waste management practices. By working together, manufacturers, climbers, trekkers, and local communities can minimise the impact of microplastics and preserve the fragile ecosystem of Mount Everest.

Solid waste management

Mount Everest, the world's tallest mountain, has been facing a solid waste management crisis due to the surge in tourism and mountaineering expeditions. The lack of proper waste disposal systems has led to environmental and health concerns, with human waste being a significant contributor to the problem.

The exponential rise in tourism has resulted in a significant amount of solid waste being generated at Mount Everest, especially during peak climbing seasons. The waste includes empty oxygen canisters, abandoned tents, food containers, human waste, and other garbage. The issue is exacerbated by the lack of a comprehensive solid waste management system, which has led to the contamination of the local watershed and the environment.

Human Waste Concerns

Human excrement is a major concern on Mount Everest. Climbers often defecate on the mountain, and while local climbers are employed to haul the waste down to base camps and dispose of it in landfills, it often gets washed downstream during the summer monsoon season. This waste contaminates the landscape and can cause health issues such as lower intestinal and upper respiratory infections, as well as waterborne diseases like cholera and hepatitis A among climbers and local communities.

Initiatives for Solid Waste Management

Several initiatives have been implemented to address the solid waste management crisis on Mount Everest:

• Sagarmatha Pollution Control Committee (SPCC): This nonprofit, non-governmental organization, established in 1991 by local Sherpa people, focuses on keeping the Khumbu region clean through waste management and education. They clean and maintain climbing routes, provide garbage collection services, and have installed trash containers along trails.
• Deposit Scheme by the Nepali Government: Since 2014, all climbers are required to pay a $4,000 deposit before the expedition. To get their money back, they must return to the Base Camp with at least 8 kilograms of waste, the average amount produced by an individual during their climb.
• Mount Everest Biogas Project: This initiative aims to build a solar-powered biogas system that uses human waste to supply local communities with sustainable fuel, addressing the human waste crisis in the region.
• Sagarmatha Next: This nonprofit, established in 2019, promotes sustainable tourism in the Khumbu region. They raise awareness through art made from trash and encourage tourists to carry bags of sorted trash back to Kathmandu for processing and recycling.
• University of Colorado Boulder's Waste Management Plan: At the request of the local government, the university developed a sustainable solid waste management plan in 2019. The plan proposes a five-step process, including waste segregation, collection, sorting, shredding, transfer to shipment stations, and transportation to recycling facilities in Kathmandu.
• The NeverRest Project: This nonprofit initiative, created during the COVID-19 pandemic, aims to revolutionize high-altitude waste management using modern technology. They presented a concept plan for a sustainable Everest base camp with portable solar tents, unisex urinals, incinerator toilets, and modular geodesic dome tents.

While these initiatives are making strides towards addressing the solid waste management crisis on Mount Everest, the increasing number of climbers continues to pose challenges. It is crucial to prioritize accountability, supervision, and the implementation of stricter waste management regulations to protect this fragile ecosystem.

Water pollution

Mount Everest, the world's tallest mountain, has been facing a pollution crisis due to the surge in tourism and mountaineering expeditions. The fragile ecosystem of the region is being spoiled by various forms of pollution, including water pollution. The contamination of the local watershed poses a significant threat to the health of the local communities surrounding Mount Everest.

The issue of human waste on Mount Everest is longstanding and well-known. Local climbers are employed to collect and haul human waste from the base camps in barrels, which are then disposed of in landfills near the village of Gorak Shep. However, the waste often ends up in rivers and streams, especially during the monsoon season. Mountain geologist Alton Byers estimated that approximately 5,400 kilograms of human waste is collected from the base camps each year, although the actual amount of waste produced is likely much higher.

The diarrhoea and intestinal problems that many visitors experience contribute to the waste issue, as the waste is not completely filtered from the water supply. This waste then washes downstream, contaminating the local watershed and posing serious health risks.

In addition to human waste, microplastics have also been detected in water samples on Mount Everest. An assessment of stream water and snow samples conducted in 2019 found that microplastics were present in all collected snow samples, with the highest concentration found at Everest Base Camp. These microplastics were mostly polyester fibres, likely originating from the clothing and equipment of climbers and trekkers.

The impact of water pollution on Mount Everest extends beyond the immediate contamination of water sources. It also contributes to the degradation of the region's fragile ecosystem and poses risks to the health and well-being of local communities. The contamination of water sources can lead to the spread of waterborne diseases, and the accumulation of waste can have long-term effects on the environment.

To address the water pollution crisis on Mount Everest, several measures have been implemented. The Sagarmatha Pollution Control Committee (SPCC), a non-profit organisation, works tirelessly to keep the region clean and promote sustainable waste management practices. The Mount Everest Biogas Project is another initiative that aims to build a solar-powered system to convert human waste into fuel for local communities, reducing the risk of water contamination. Additionally, the Nepali government has also launched clean-up campaigns and deposit initiatives to encourage climbers to bring their waste back down the mountain.

Air pollution

Mount Everest has been facing a pollution crisis due to the increasing number of tourists and adventurers visiting the mountain every year. The mountain, located in the Mahalangur Himal sub-range of the Himalayas in Nepal, is the world's highest mountain at 8,848-8,850 metres (29,029 feet) above sea level. Since Edmund Hillary and Tenzing Norgay became the first people to reach the summit in 1953, thousands of people have attempted to climb Mount Everest, with the number of tourists in the Sagarmatha National Park, where Mount Everest is located, increasing from 3,600 in 1979 to more than 58,000 in 2019. This surge in tourism has led to significant pollution issues, particularly air pollution, which is caused by a variety of factors.

Firstly, air pollution on Mount Everest is caused by the burning of garbage by lodge owners in the Khumbu region. According to mountain geologist Alton Byers, lodge owners burn plastic, aluminium beer cans, glass whiskey bottles, and paper products in pits ranging from 270 to 2,150 square feet (25 to 100 square metres). The burning of these items releases poisons into the air, contributing to air pollution in the region.

Secondly, the lack of proper waste management systems for human waste has resulted in air pollution on Mount Everest. Human excrement is often bagged and thrown into riverbeds, only to be washed downstream during the monsoon season. This waste also accumulates in the snow and is periodically regurgitated by the glaciers. The issue of human waste is exacerbated by the high incidence of diarrhoea and other intestinal problems among visitors, leading to an estimated 12,000 lbs (5,400 kilograms) of human waste produced at the base camps each year.

Additionally, the increasing number of expeditions and trekkers on Mount Everest has resulted in air pollution caused by the use of portable gas stoves, as well as the release of toxins from the decomposition of waste left on the mountain. The high-altitude expeditions require the use of life-supporting equipment, such as tents, ropes, ladders, tins, and cans, which contribute to the waste issues. The combination of human waste and non-biodegradable trash has led to an estimated 30 tonnes of garbage covering the highest point on Earth.

Furthermore, microplastics have been found to be omnipresent in snow samples collected from Mount Everest, with the highest concentration found at the Everest Base Camp. These microplastics are linked to fibres from outdoor clothing, particularly polyester, acrylic, nylon, and polypropylene. The clothing and equipment used by climbers and trekkers are significant contributors to air pollution in the region.

Finally, deforestation in the area surrounding Mount Everest also contributes to air pollution. Trees are felled to make lodges and provide firewood for the increasing number of tourists. This loss of vegetation reduces the ability to absorb pollutants, leading to increased air pollution in the region.

Overall, the increasing tourism and adventure activities on Mount Everest have led to a range of air pollution issues, including the burning of garbage, improper disposal of human waste, decomposition of trash, microplastics, and deforestation. These issues pose a serious threat to the fragile ecosystem of the region and the health of local communities.
