Tourism, while a boon for economies and cultural exchange, can significantly impact the environment. At SIXT.VN, we believe in responsible travel and providing convenient services that minimize environmental impact. This article explores how tourism contributes to pollution and offers insights into sustainable tourism practices to preserve Vietnam’s beauty for generations to come.
1. What are the Main Ways Tourism Contributes to Pollution?
Tourism contributes to pollution through several key avenues, including depletion of natural resources, air and noise pollution, solid waste generation, sewage and wastewater production, and aesthetic pollution. Each of these factors can degrade the environment and impact local communities.
1.1. Resource Depletion
Tourism can deplete natural resources like water, energy, and land, especially when consumption exceeds sustainable levels. This puts pressure on local resources, particularly in regions where these resources are already scarce.
1.2. Water Overuse
Water is essential, but the tourism industry often overuses it for hotels, swimming pools, golf courses, and tourist consumption. This can lead to shortages and degradation, with hotels and resorts often consuming significantly more water than local communities. According to a study by the United Nations Environment Programme (UNEP), tourism in water-scarce regions can exacerbate water stress.

1.3. Impact of Golf Courses
Golf courses, popular among tourists, require large amounts of water for maintenance, leading to scarcity and potential saline intrusion if water is pumped from wells. An average golf course in a tropical country needs 1500kg of chemical fertilizers, pesticides, and herbicides per year and uses as much water as 60,000 rural villagers, according to Tourism Concern.
1.4. Local Resource Strain
Tourism can strain local resources like energy, food, and raw materials, especially in areas with seasonal tourism peaks. This demand can lead to shortages and increased environmental impacts associated with resource extraction and transportation.
1.5. Land Degradation
The construction of tourism facilities can increase pressure on land resources, including forests, wetlands, and scenic landscapes, leading to habitat loss and ecosystem degradation. Forests suffer deforestation due to fuel wood collection and land clearing. For example, a trekking tourist in Nepal can use four to five kilograms of wood a day, exacerbating deforestation.
2. How Does Tourism Contribute to Air and Noise Pollution?
Tourism significantly contributes to air and noise pollution through transportation, energy consumption, and recreational activities. These factors can degrade air quality and disturb wildlife and local communities.
2.1. Air Pollution from Transportation
Transport by air, road, and rail is continuously increasing due to tourism, accounting for a significant share of air emissions. A single transatlantic return flight emits almost half the CO2 emissions produced by all other sources consumed by an average person yearly, according to Mayer Hillman in Town & Country Planning magazine, September 1996.
2.2. Global Impact of Air Pollution
Transport emissions and emissions from energy production and use are linked to acid rain, global warming, and photochemical pollution. Air pollution from tourist transportation has impacts on the global level, especially from carbon dioxide (CO2) emissions related to transportation energy use, according to the World Tourism Organization (UNWTO).
2.3. Local Air Pollution from Tourism
Tourist activities, such as tour buses leaving their motors running, contribute to severe local air pollution, especially in hot or cold climates. Buses often idle for extended periods, emitting pollutants while tourists are on excursions.
2.4. Noise Pollution Effects
Noise pollution from airplanes, cars, buses, and recreational vehicles like snowmobiles and jet skis is an ever-growing problem. It causes annoyance, stress, and even hearing loss for humans and distress to wildlife, altering their natural activity patterns.

2.5. Noise Impact on Wildlife
Noise generated by snowmobiles, for instance, can cause animals to alter their natural activity patterns. In winter 2000, 76,271 people entered Yellowstone National Park on snowmobiles, outnumbering visitors in cars, snowcoaches, and skis. A survey found that snowmobile noise could be heard 70% of the time at 11 of 13 sample sites, even drowning out the sound of the Old Faithful geyser, according to Idahonews.
3. What Role Does Solid Waste and Littering Play in Tourism Pollution?
Solid waste and littering in tourist areas can severely degrade the environment, affecting rivers, scenic areas, and roadsides. Improper waste disposal can lead to long-term pollution and harm to wildlife.
3.1. Waste Disposal Issues
In areas with high concentrations of tourist activities, waste disposal is a serious problem. Cruise ships in the Caribbean are estimated to produce more than 70,000 tons of waste each year, according to the UNEP. Some cruise lines are actively working to reduce waste-related impacts.
3.2. Impacts of Solid Waste
Solid waste and littering can degrade the physical appearance of water and shorelines and cause the death of marine animals. Plastics and other non-biodegradable materials can persist in the environment for decades, harming ecosystems.
3.3. Waste in Mountain Areas
In mountain areas, trekking tourists generate a great deal of waste, leaving behind garbage, oxygen cylinders, and even camping equipment. Trails in the Peruvian Andes and Nepal frequently visited by tourists have been nicknamed “Coca-Cola trail” and “Toilet paper trail” due to the high volume of litter.
3.4. Cruise Ship Waste
The Wider Caribbean Region receives 63,000 port calls from ships each year, generating 82,000 tons of garbage. About 77% of all ship waste comes from cruise vessels. Passengers on a cruise ship each account for 3.5 kilograms of garbage daily, compared with the 0.8 kilograms generated by people on shore, according to Our Planet, UNEP magazine for environmentally sustainable development, volume 10, no. 3, 1999.
4. How Does Sewage from Tourism Pollute the Environment?
Sewage from tourism facilities can lead to increased pollution, damaging flora and fauna in surrounding waters. Wastewater often pollutes seas and lakes near tourist attractions, leading to ecological imbalances.
4.1. Sewage Pollution Impacts
Construction of hotels, recreation, and other facilities often leads to increased sewage pollution. Wastewater has polluted seas and lakes surrounding tourist attractions, damaging the flora and fauna.

4.2. Coral Reef Damage
Sewage runoff causes serious damage to coral reefs because it stimulates the growth of algae, which cover the filter-feeding corals, hindering their ability to survive. Changes in salinity and siltation can have wide-ranging impacts on coastal environments.
4.3. Health Threats
Sewage pollution can threaten the health of humans and animals. Contaminated water sources can spread diseases and pathogens, posing risks to both tourists and local populations.
5. What is Aesthetic Pollution and How Does Tourism Contribute?
Aesthetic pollution occurs when tourism development fails to integrate with the natural environment and local architecture, resulting in visual degradation of landscapes.
5.1. Architectural Disharmony
Often, tourism fails to integrate its structures with the natural features and indigenous architecture of the destination. Large, dominating resorts of disparate design can look out of place in any natural environment and may clash with the indigenous structural design.
5.2. Land Use Planning Issues
A lack of land-use planning and building regulations in many destinations has facilitated sprawling developments along coastlines, valleys, and scenic routes. The sprawl includes tourism facilities themselves and supporting infrastructure such as roads, employee housing, parking, service areas, and waste disposal.
6. What are the Physical Impacts of Tourism on Ecosystems?
Tourism can lead to physical impacts such as the degradation of ecosystems, especially in ecologically fragile areas like alpine regions, rainforests, wetlands, mangroves, coral reefs, and seagrass beds.
6.1. Ecosystem Degradation
Attractive landscape sites, such as sandy beaches, lakes, riversides, and mountain tops and slopes, are often transitional zones, characterized by species-rich ecosystems. Typical physical impacts include the degradation of such ecosystems.
6.2. Threats to Fragile Areas
The ecosystems most threatened with degradation are ecologically fragile areas such as alpine regions, rainforests, wetlands, mangroves, coral reefs, and seagrass beds. The threats to and pressures on these ecosystems are often severe because such places are very attractive to both tourists and developers.
6.3. Mountain Environments
In industrial countries, mass tourism and recreation are now fast overtaking the extractive industries as the largest threat to mountain communities and environments. Visits to the 10 most popular mountainous national parks in the United States have increased twelve-fold since 1945, according to People and the Planet.
6.4. Himalayan Tourism
Every year in the Indian Himalaya, more than 250,000 Hindu pilgrims, 25,000 trekkers, and 75 mountaineering expeditions climb to the sacred source of the Ganges River, the Gangotri Glacier. They deplete local forests for firewood, trample riparian vegetation, and strew litter.
7. How Do Construction and Infrastructure Development Impact the Environment?
Construction and infrastructure development for tourism facilities can lead to significant environmental damage, including sand mining, erosion, and loss of wildlife habitats.
7.1. Impacts of Construction Activities
The development of tourism facilities such as accommodation, water supplies, restaurants, and recreation facilities can involve sand mining, beach and sand dune erosion, soil erosion, and extensive paving. Road and airport construction can lead to land degradation and loss of wildlife habitats and deterioration of scenery.
7.2. Yosemite National Park Example
In Yosemite National Park, the number of roads and facilities have been increased to keep pace with the growing visitor numbers and to supply amenities, infrastructure, and parking lots for all these tourists. These actions have caused habitat loss in the park and are accompanied by various forms of pollution including air pollution from automobile emissions, as reported by the Sierra Club.
7.3. Deforestation and Land Use
Construction of ski resort accommodation and facilities frequently requires clearing forested land. Coastal wetlands are often drained and filled due to a lack of more suitable sites for the construction of tourism facilities and infrastructure. These activities can cause severe disturbance and erosion of the local ecosystem, even destruction in the long term.
7.4. Marina Development
Development of marinas and breakwaters can cause changes in currents and coastlines. Extraction of building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and destruction of habitats.
7.5. Coral Reef Damage in Coastal Areas
In the Philippines and the Maldives, dynamiting and mining of coral for resort building materials has damaged fragile coral reefs and depleted the fisheries that sustain local people and attract tourists. Overbuilding and extensive paving of shorelines can result in the destruction of habitats and disruption of land-sea connections, such as sea-turtle nesting spots.

7.6. Impacts on Coral Reefs
Coral reefs are especially fragile marine ecosystems and are suffering worldwide from reef-based tourism developments. Evidence suggests a variety of impacts to coral result from shoreline development, increased sediments in the water, trampling by tourists and divers, ship groundings, pollution from sewage, overfishing, and fishing with poisons and explosives that destroy coral habitat.
8. How Do Tourist Activities Directly Impact the Environment?
Tourist activities such as trampling, anchoring, and wildlife viewing can directly impact the environment, leading to habitat degradation and disturbance of wildlife.
8.1. Trampling Effects
Tourists using the same trail over and over again trample the vegetation and soil, eventually causing damage that can lead to loss of biodiversity and other impacts. Such damage can be even more extensive when visitors frequently stray off established trails.
8.2. Table: Trampling Impacts
| Trampling Impacts on Vegetation | Trampling Impacts on Soil |
|---|---|
| Breakage and bruising of stems | Loss of organic matter |
| Reduced plant vigor | Reduction in soil macro porosity |
| Reduced regeneration | Decrease in air and water permeability |
| Loss of ground cover | Increase in run off |
| Change in species composition | Accelerated erosion |

8.3. Anchoring and Marine Activities
In marine areas, many tourist activities occur in or around fragile ecosystems. Anchoring, snorkeling, sport fishing and scuba diving, yachting, and cruising are some of the activities that can cause direct degradation of marine ecosystems such as coral reefs, and subsequent impacts on coastal protection and fisheries.
8.4. Cruise Ship Damage to Coral Reefs
There are 109 countries with coral reefs. In 90 of them, reefs are being damaged by cruise ship anchors and sewage, by tourists breaking off chunks of coral, and by commercial harvesting for sale to tourists. One study of a cruise ship anchor dropped in a coral reef for one day found an area about half the size of a football field completely destroyed, and half again as much covered by rubble that died later, as mentioned in Ocean Planet.
8.5. Wildlife Disturbance
Wildlife viewing can bring about stress for the animals and alter their natural behavior when tourists come too close. Safaris and wildlife watching activities have a degrading effect on habitat as they often are accompanied by the noise and commotion created by tourists as they chase wild animals in their trucks and aircraft.
8.6. Behavioral Changes in Animals
This puts high pressure on animal habits and behaviors and tends to bring about behavioral changes. In some cases, as in Kenya, it has led to animals becoming so disturbed that at times they neglect their young or fail to mate.
9. What Can Be Done to Mitigate Tourism’s Impact on Pollution?
Mitigating tourism’s impact on pollution requires a multi-faceted approach involving sustainable practices, responsible tourism policies, and community engagement.
9.1. Sustainable Tourism Practices
