How Does Tourism Affect the Environment? A Comprehensive Guide

Tourism significantly impacts the environment. Are you curious about how your travel choices influence the world around you? At SIXT.VN, we’re dedicated to sustainable travel and want to help you understand the relationship between tourism and the environment in Vietnam and beyond. By exploring the effects of tourism, we can all make more responsible travel decisions and help preserve Vietnam’s stunning landscapes. Let’s dive into the complex issue of tourism’s environmental footprint and discover how to travel more responsibly.

1. Understanding the Three Main Impact Areas of Tourism on the Environment

Tourism has a profound effect on the environment, especially when the number of tourists exceeds the ecosystem’s ability to handle the influx. Unregulated traditional tourism can harm natural areas by causing soil erosion, increased pollution, marine discharges, habitat loss, pressure on endangered species, and a higher risk of forest fires. It often strains water resources and forces locals to compete for essential resources.

1.1 What is the Definition of “Acceptable Limits of Change” in Tourism?

“Acceptable Limits of Change” in tourism refers to the threshold beyond which the negative impacts of tourism on the environment and local communities become unacceptable. This concept aims to manage tourism in a way that preserves the natural and cultural resources of a destination. The acceptable limits vary depending on the specific environment, local culture, and community values.

1.2 Why Is Uncontrolled Tourism Harmful?

Uncontrolled tourism can degrade natural areas by causing:

• Soil Erosion: Increased foot traffic and construction can lead to soil erosion, damaging landscapes and ecosystems.
• Pollution: More visitors often mean more waste, sewage, and air pollution.
• Habitat Loss: Construction for hotels and attractions can destroy natural habitats, threatening local flora and fauna.
• Resource Strain: Increased demand for water, energy, and food can deplete local resources.

1.3 How Does Tourism Affect Endangered Species?

Tourism can significantly impact endangered species through habitat destruction, increased pollution, and disturbances to their natural behaviors.

• Habitat Destruction: The construction of hotels, resorts, and other tourism-related infrastructure often leads to the destruction and fragmentation of habitats, leaving endangered species with less space to live and reproduce.
• Increased Pollution: Tourism can lead to increased pollution levels, including air, water, and noise pollution. These pollutants can directly harm endangered species, contaminate their food sources, and disrupt their reproductive cycles.
• Disturbance to Natural Behaviors: Wildlife tourism, if not managed responsibly, can disrupt the natural behaviors of endangered species. Tourists may approach animals too closely, causing stress and altering their feeding, mating, and nesting habits.

2. Depletion of Natural Resources Due to Tourism

Tourism can deplete natural resources by increasing consumption in areas where resources are already scarce, impacting water, local supplies, and land.

2.1 How Does Tourism Affect Water Resources?

Tourism can strain water resources. The tourism industry uses a lot of water for hotels, swimming pools, golf courses, and tourists’ personal use. This can lead to water shortages and poor water quality, along with more wastewater. In dry areas like the Mediterranean, water scarcity is a big issue. Tourists often use more water on vacation than at home, sometimes up to 440 liters a day, almost twice what people in a Spanish city use.

Golf courses also use a lot of fresh water. Golf tourism is becoming more popular, so more golf courses are being built. These courses need a lot of water every day. If the water comes from wells, overpumping can cause saltwater to get into the groundwater. Golf resorts are increasingly located near protected areas or places with limited resources, making the impact worse.

According to Tourism Concern, a typical golf course in a tropical country like Thailand requires 1500 kg of chemical fertilizers, pesticides, and herbicides per year and uses as much water as 60,000 rural villagers.

2.1.1 What Measures Can Hotels Take to Conserve Water?

Hotels can implement several measures to conserve water, including:

• Installing low-flow showerheads and toilets.
• Encouraging guests to reuse towels and linens.
• Using efficient irrigation systems for landscaping.
• Monitoring and repairing leaks promptly.

2.2 How Does Tourism Impact Local Resources?

Tourism can put a strain on local resources like energy, food, and raw materials, which may already be in short supply. More extraction and transport of these resources make the physical impacts of using them worse. Many tourist destinations have ten times more people in the high season than in the low season. These resources are in high demand to meet tourists’ expectations, such as proper heating and hot water.

2.3 What is Land Degradation and How Does Tourism Contribute to It?

Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain-fed cropland, irrigated cropland, or range, pasture, forest, and woodlands. Tourism contributes to land degradation through:

• Construction: Building hotels and recreational facilities increases pressure on land resources and scenic landscapes.
• Deforestation: Clearing forests for fuel wood and land exacerbates the problem.
• Infrastructure Development: Building roads and other infrastructure can lead to soil erosion and habitat loss.

One trekking tourist in Nepal, an area already affected by deforestation, can use four to five kilograms of wood a day.

3. Understanding Pollution Caused by Tourism

Tourism can cause various types of pollution, just like any other industry, including air emissions, noise, solid waste, sewage, and even visual pollution.

3.1 How Does Tourism Contribute to Air Pollution and Noise?

Air and noise pollution are significant environmental impacts of tourism, largely stemming from transportation and energy consumption. The rising number of tourists leads to more air, road, and rail travel, which increases air emissions. Tourism is responsible for a significant portion of air travel, contributing to air pollution.

According to one study, a single transatlantic return flight emits almost half the CO2 emissions produced by an average person yearly for all other sources, such as lighting, heating, and car use (Mayer Hillman, Town & Country Planning magazine, September 1996. Source: MFOE).

Transport emissions and energy production contribute to acid rain, global warming, and photochemical pollution. Air pollution from tourist transportation impacts the global level, especially through carbon dioxide (CO2) emissions from transportation energy use, and can cause severe local air pollution.

Noise pollution from airplanes, cars, buses, and recreational vehicles like snowmobiles and jet skis is a growing problem. It causes annoyance, stress, and hearing loss for humans and distress to wildlife, especially in sensitive areas. For example, snowmobile noise can disrupt animals’ natural activity patterns.

In winter 2000, 76,271 people entered Yellowstone National Park on snowmobiles, outnumbering the 40,727 visitors who came in cars. A survey found that snowmobile noise could be heard 70% of the time at 11 of 13 sample sites and 90% of the time at 8 sites. At the Old Faithful geyser, snowmobiles could be heard 100% of the time during the daytime, drowning out even the sound of the geyser erupting.

3.1.1 What are the Effects of Noise Pollution on Wildlife?

Noise pollution can disrupt wildlife by interfering with their communication, hunting, and reproductive behaviors. Animals may also experience stress and alter their migration patterns.

3.2 How Do Solid Waste and Littering Impact the Environment Due to Tourism?

Solid waste and littering are serious problems in areas with high tourist activity and natural attractions. Improper waste disposal can severely damage the environment, polluting rivers, scenic areas, and roadsides. For example, cruise ships in the Caribbean produce over 70,000 tons of waste each year. While some cruise lines are working to reduce waste-related impacts, solid waste and littering can degrade the appearance of water and shorelines and cause marine animal deaths.

In mountain areas, trekking tourists produce a lot of waste, leaving behind garbage, oxygen cylinders, and camping equipment. This pollutes remote areas with limited garbage collection or disposal facilities. Some trails in the Peruvian Andes and Nepal are nicknamed “Coca-Cola trail” and “Toilet paper trail” due to the amount of litter.

The Wider Caribbean Region, stretching from Florida to French Guiana, receives 63,000 port calls from ships each year, generating 82,000 tons of garbage. Cruise vessels account for about 77% of all ship waste. The average cruise ship carries 600 crew members and 1,400 passengers, with each passenger generating 3.5 kilograms of garbage daily, compared to the 0.8 kilograms generated by people on shore. (Source: Our Planet, UNEP magazine for environmentally sustainable development, volume 10, no. 3, 1999)

3.2.1 What are Some Effective Waste Management Strategies for Tourist Destinations?

Effective waste management strategies include:

• Implementing recycling programs.
• Providing adequate waste disposal facilities.
• Educating tourists about responsible waste disposal.
• Enforcing regulations against littering.

3.3 What is the Impact of Sewage on the Environment Due to Tourism?

The construction of hotels, recreational facilities, and other tourism-related infrastructure often leads to increased sewage pollution. Wastewater pollutes seas and lakes near tourist attractions, harming the flora and fauna. Sewage runoff damages coral reefs by stimulating algae growth, which covers corals and hinders their survival. Changes in salinity and siltation can also significantly impact coastal environments. Sewage pollution can threaten the health of both humans and animals.

3.4 What is Aesthetic Pollution and How Does Tourism Cause It?

Aesthetic pollution occurs when tourism developments fail to blend with the natural environment and local architecture. Large, out-of-place resorts can look unnatural and clash with indigenous structural designs. A lack of land-use planning and building regulations in many destinations has led to sprawling developments along coastlines, valleys, and scenic routes. This sprawl includes tourism facilities and supporting infrastructure like roads, employee housing, parking, service areas, and waste disposal.

4. Examining the Physical Impacts of Tourism

Attractive landscape sites, such as sandy beaches, lakes, riversides, and mountain slopes, are often transitional zones with species-rich ecosystems. Typical physical impacts include the degradation of these ecosystems. An ecosystem is a geographic area that includes all living organisms (people, plants, animals, and microorganisms), their physical surroundings (soil, water, and air), and the natural cycles that sustain them. The ecosystems most threatened with degradation are ecologically fragile areas such as alpine regions, rain forests, wetlands, mangroves, coral reefs, and sea grass beds. These places are very attractive to both tourists and developers.

In industrial countries, mass tourism and recreation are now overtaking the extractive industries as the largest threat to mountain communities and environments. Since 1945, visits to the 10 most popular mountainous national parks in the United States have increased twelve-fold. In the European Alps, tourism now exceeds 100 million visitor-days. 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. Even worse, this tourism frequently induces poorly planned, land-intensive development.

4.1 How Does Tourism Development Cause Physical Impacts?

Physical impacts are caused not only by tourism-related land clearing and construction but by continuing tourist activities and long-term changes in local economies and ecologies.

4.1.1 Construction Activities and Infrastructure Development

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. In addition, road and airport construction can lead to land degradation and loss of wildlife habitats and deterioration of scenery.

In Yosemite National Park (US), 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; the Sierra Club has reported “smog so thick that Yosemite Valley could not be seen from airplanes”. This occasional smog is harmful to all species and vegetation inside the Park. (Source: Trade and Environment Database)

4.1.2 Deforestation and Unsustainable 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 construction of tourism facilities and infrastructure. These activities can cause severe disturbance and erosion of the local ecosystem, even destruction in the long term.

4.1.3 Marina Development

The development of marinas and breakwaters can cause changes in currents and coastlines. Furthermore, extracting building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and the destruction of habitats. In the Philippines and the Maldives, dynamiting and mining 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. 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.

4.2 What are the Physical Impacts from Tourist Activities?

Tourist activities can significantly impact the environment through trampling, marine activities, and ecosystem alterations.

4.2.1 Trampling

Tourists using the same trail repeatedly 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.

4.2.2 Anchoring and Other Marine Activities

In marine areas (around coastal waters, reefs, beaches and shorelines, offshore waters, uplands, and lagoons), many tourist activities occur in or around fragile ecosystems. Anchoring, snorkeling, sport fishing, scuba diving, yachting, and cruising can cause direct degradation of marine ecosystems such as coral reefs, and subsequent impacts on coastal protection and fisheries.

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. It was estimated that coral recovery would take fifty years. (Source: Ocean Planet)

4.2.3 Alteration of Ecosystems by Tourist Activities

Habitat can be degraded by tourism leisure activities. For example, 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. 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.
