What are the social impacts of tourism on the Great Barrier Reef?
Increases in crowding, prices, or crime are negative social impacts of tourism on the Great Barrier Reef. Additionally, “Increasing tourism may also result in increasing conflict between various uses and, within the same uses, between commercial, recreational and indigenous interests” (Australia State, 2004).
How does tourism affect coral reefs?
How Tourism Threatens Corals. When tourists accidently touch, pollute or break off parts of the reef, corals experience stress. The coral organisms try to fight off the intrusion, but this process often leads to coral bleaching—when corals expel the brightly colored algae that live in them and become completely white.
What is Australia doing to protect the Great Barrier Reef?
Australia is working towards putting these control measures in place to try and help The Great Barrier Reef stay as healthy as it is now. There are many food webs in The Great Barrier Reef. Tourism can have negative impacts on these food webs so we have to try and protect all flora and fauna to stop this happening.
What are the threats to the Great Barrier Reef’s future?
Climate change is the biggest threat to the Reef’s future. It can affect the Reef in a number of ways, including increased frequency of severe weather events, ocean acidification, rising sea temperature and rising sea levels. Rising sea temperatures has a negative impact in the species life cycles and this could have a consequence to the food webs.
How much of the Great Barrier Reef is affected by tourism?
about 7 per centIts long-term attractiveness as a tourism destination is largely based on the Great Barrier Reef being the world's largest, best-known and best-managed coral reef which is home to a spectacular and diverse array of species. Tourism is concentrated in about 7 per cent of the total Great Barrier Reef Marine Park.
Is tourism destroying the Great Barrier Reef?
Although many people think that travellers are a major contributor to the damage, the truth is that around 80% of all tourism activity occurs within just 7% of the Great Barrier Reef Marine Park, and is far from the biggest threat to this fragile ecosystem.
What are the negative impacts of tourism?
Tourism puts enormous stress on local land use, and can lead to soil erosion, increased pollution, natural habitat loss, and more pressure on endangered species. These effects can gradually destroy the environmental resources on which tourism itself depends.

How is the Great Barrier Reef getting destroyed?
The damage to the reef is a result of ocean warming, acidification and extreme weather, which has resulted in coral bleaching, according to the International Union for Conservation of Nature's (IUCN) 2020 World Heritage Outlook report, which tracks whether the conservation of the world's 252 natural World Heritage ...
Is tourism good for coral reefs?
The economic contribution of tourism to coral reefs is estimated at $36 billion to the global economy each year—this revenue supports millions of jobs in restaurants, hotels, tour operations, transportation companies, and more.
What are the current threats to the Great Barrier Reef?
Excess nutrients, fine sediments and pesticides from agricultural run-off and other industries pose the biggest risk to reef water quality....The other main threats to the Reef include:poor water quality from land-based run-off.impacts from coastal development.direct human use such as illegal fishing and bycatch.
Will the Great Barrier Reef still exist in 2050?
(CNN) — Australia's Great Barrier Reef seems indestructible from afar: Its 2,600-kilometer-long clusters of corals are even visible from outer space. But on closer examination, the story loses some of its beauty. The reef -- along with the multibillion dollar tourist industry it supports -- could be extinct by 2050.
How does tourism affect the Great Barrier Reef?
Many aspects caused by tourism including climate change and fishing can affect the breeding cycle which then affects the food webs. There are many food webs in The Great Barrier Reef, below are some examples:
Why is the Great Barrier Reef important?
The Great Barrier Reef was and still is a very important place to the Indigenous people, and it will continue to have the same value.
What would happen if corals were extinct?
If coral becomes extinct in the Great Barrier Reef, the money and jobs created from the reef will become obsolete as well.
What is buoyancy in the Great Barrier Reef?
Buoyancy refers to the force that supports the weight of an organism. Viscosity is the resistance to the movement of sea water. These two abiotic factors contribute to the movement of fish and sea mammals. Light penetrates the ocean surface only about 20 meters. There is much more salt in the Great Barrier Reef than in a fresh water ecosystem.
How many traditional owner groups are there in the Great Barrier Reef?
Today there are over 70 traditional owner groups whose sea country include The Great Barrier Reef. The Great Barrier Reef works with Indigenous people to acknowledge their continuing social, cultural, economic and spiritual connections.
How much light penetrates the ocean surface?
Light penetrates the ocean surface only about 20 meters. There is much more salt in the Great Barrier Reef than in a fresh water ecosystem. The density of water in the Great Barrier Reef changes with depth, which changes the biotic components that can live in a given depth. Tourism involves many people who visit this magnificent marine ecosystem, ...
How many species of fish are there in the Great Barrier Reef?
It includes 600 types of soft and hard corals, more than 100 species of jelly fish, 3000 varieties of molluscs, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more than 30 species of whales and dolphins.

The Solution Exchange explored ways to both improve access to tourism jobs for First Nations Peoples and communities, as well as opportunities to diversify local livelihoods so they are not solely reliant on reef assets.
How does tourism affect the Great Barrier Reef?
The environmental impacts of tourism at the Great Barrier Reef concern recreational and commercial fishing that removes large predatory species from the reef ecosystem. Researchers are unsure of the effects of selective removal of such fish. However, it is known that shore-based recreational fishing, competing for species with commercial fishing, may have effects on shore populations of invertebrates that are collected for bait in areas that are intensively visited. What is more, there are innumerable people that scuba dive each year at the Great Barrier Reef using registered, privately owned motor vessels as well as smaller craft. According to the Australia State of the Environment Report 2001 (2004), “Activities associated with the use of this equipment have the potential to affect the environment through pollution of water (boat sullage) and disturbance of species and habitats.”
How many people work on the Great Barrier Reef?
Tourism on the Great Barrier Reef employs around 47,000 people. Yet, Australian residents in a survey ranked the impacts of reef tourism as a high threat to the great coral reef system. On the other hand, those who are professionally experienced in reef environmental issues ranked reef tourism as a much smaller threat as compared to other widespread impacts such as coral bleaching, agricultural runoff, and fishing. Therefore, the environmental threat of tourism on the Great Barrier Reef is largely an exaggeration. Nevertheless, it is essential for tourism managers to protect the great coral reef system from damage as much as they can. Vicki J. Harriott (2004) writes that “Industry and management agencies have included education of reef visitors and tourism staff as part of a planned framework for sustainable tourism and recreation, and this education program should include promotion of a greater understanding of reef environmental issues.” After all, mismanaged places cannot remain as wonders of the world for too long.
What are the concerns of tourism management?
These concerns of tourism management include the protection of coral reefs and other habitats such as seagrass from anchor damage, poor diving practices, waste disposal, reef walking and collecting; protection of nestling turtles and sea birds from disturbance; protection of whales, dugongs and turtles from interference and vessel collisions; prevention of littering because some animals may mistake litter for nutrients and others may get trapped in the litter such as ring pulls from soft drink cans, or discarded fishing line; respect of the cultural importance of the Great Barrier Reef to Aboriginal and Torrest Strait Islanders; and minimization of conflict in access within the multiple use Marine Park. The crown of thorns starfish outbreaks have been identified as another cause of concern in the area. These outbreaks may have been caused by human use of the coastal zone increasing nutrient loads, or the removal of predators. The Great Barrier Reef Marine Park Authority also recognizes that these outbreaks may simply be a natural phenomenon, and therefore nothing to hold tourists responsible for (Frequently Asked Questions).
Where is the Great Barrier Reef located?
The Great Barrier Reef is the world’s largest coral reef system, located in the Coral Sea, off the coast of Queensland in northeast Australia. This coral reef system is composed of approximately three thousand individual reefs in addition to nine hundred islands, stretching for 2,600 kilometers and covering an area of approximately 344,400 square kilometers. A huge part of the reef is protected by the Great Barrier Reef Marine Park, which happens to be the world’s largest marine park, established in 1975, and covering an area of 345,000 square kilometres (Great Barrier Reef, 2007; Shipping Safety, 2001).
Is the Great Barrier Reef a wonder of the world?
Labelled as one of the seven wonders of the world, the Great Barrier Reef truly is a cause of celebration for humanity . Hence, even though there are obvious environmental and social impacts of tourism in the area, Australia does not explicitly limit the number of tourists at the world’s largest coral reef system. After all, the Great Barrier Reef is a World Heritage Site, essentially belonging to the entire human race! Hence, the Great Barrier Reef Marine Park Authority has identified several points of concern that tourism management in the area would be working on so as to help the Great Barrier Reef remain a wonder of the world.
Is the Great Barrier Reef a tourist attraction?
Undoubtedly, the Great Barrier Reef is a very popular tourist destination for people from within and outside Australia who do not get to see the marvel from outer space. Scuba divers are especially attracted to this tourist destination. Vast biodiversity, warm and clear waters, and the Great Barrier Reef’s accessibility from the floating guest facilities known as “live aboards” make it even more appealing. Along the coast of Queensland today, there are many cities that offer boat trips to the great coral reef system on a daily basis. Besides, various continental islands have been turned into resorts to sustain tourism in the area (Great Barrier).
Is the Great Barrier Reef threatened by tourism?
According to the Queensland Premier, Peter Beattie, the Great Barrier Reef is not under an environmental threat caused by tourism alone. Rather, marine species that rely on coastal freshwater wetlands and estuaries as breeding and nursery areas have had their habitat damaged since the time of European settlement because of development on the land. Hence, local governments, communities, and groups such as land holders, agricultural industries and tourism must all join forces to protect the ecology of the great reef system seeing that the development on the land increases pollutant loads in the rivers.
How does coastal development affect coral reefs?
This sediment load increases the turbidity in coral reef waters, decreasing the amount of sunlight that can penetrate through the water to reach the corals.
How does sewage pollution affect coral reefs?
Such sewage pollution leads to nutrient enrichment in ocean water, which favors algal growth at the expense of coral organisms. Inappropriate solid waste disposal can lead to the leaching of toxic chemicals into local waters, and litter ( including plastic litter) and debris can blow and wash into coral reef waters [3].
What happens to corals when sediment is heavy?
Heavy sedimentation can also lead to decreased coral growth rates, decreased productivity and decreased recruitment.
What are the physical effects of snorkeling and diving?
While most diving and snorkeling activities have little physical impact on coral reefs, physical damages to corals can and do occur when people stand on, walk on, kick, touch, trample, and when their equipment contacts corals.
What are the effects of fish feeding on coral reefs?
Fish feeding and encounters with charismatic or rare species can alter the natural behavior of coral reef species, such as foraging behavior, changes in home range size, population density, migration patterns, and reproductive activities.
Where do coral reefs exist?
Coral reefs exist in warm tropical regions around the equator that we love to visit when we travel [1]. Unfortunately, our love affair with coral reefs is causing them to be “loved to death”. While ecotourism has the potential to be a sustainable way to support coastal communities and economies in reef regions without negatively impacting natural ...
What is the effect of tourist fishing on local fish stocks?
An abundance of tourist fishing and consumption of local fish stocks may lead to overexploitation and competition with local fishers.
What are the threats to coral reefs?
And since the disruption of one ocean system impacts all the others, sea grass and mangroves—shallow-water plant species vital to the health of the marine ecosystem—are also threatened by coral stress. Another significant problem facing coral reefs is sedimentation.
What are the problems that coral reefs face?
Another significant problem facing coral reefs is sedimentation. When dirt and debris are deposited into the ocean, they pollute marine ecosystems and block the sunlight algae need for photosynthesis. When light is blocked, the immobile coral reefs bleach and die.
What happens when light is blocked in Costa Rica?
When light is blocked, the immobile coral reefs bleach and die. In Costa Rica, sources of sedimentation include dredging, logging, agriculture and coastal development driven by the tourism industry. A study by biologist Jorge Cortés documents a decade of negative impacts from tourism on coral reefs in the Cauhita region of Costa Rica.
Why do corals bleach?
When tourists accidently touch, pollute or break off parts of the reef, corals experience stress. The coral organisms try to fight off the intrusion, but this process often leads to coral bleaching—when corals expel the brightly colored algae that live in them and become completely white.
How much of the world's coral reefs are damaged?
Studies show that globally, 30 percent of coral reefs are already seriously damaged. Seventy percent of all reefs are expected to disappear by 2030 if we don’t take corrective action to stop the negative human impacts of climate change on coral reef communities.
How much of the Pacific reef is at risk of sedimentation?
Sedimentation will continue to devastate Pacific reefs if better management principles are not enacted. Scientists predict that 50 percent of all coral reefs in Latin America are at risk of degradation in the next five to 10 years. Studies show that globally, 30 percent of coral reefs are already seriously damaged.
Why do hotels dump graywater?
Many coastal hotels dump their graywater—wastewater from laundry, cooking and household sinks—into the ocean, contributing to sedimentation and the contamination of coral reefs. It’s important to be aware of the fact that many land-based activities may directly harm the marine ecosystem.
Why is the Great Barrier Reef under threat?
The Great Barrier Reef is under threat from a range of pressures with a major one being deteriorating water quality due to pollution from adjacent land use.
What are the threats to the Great Barrier Reef?
The Great Barrier Reef is under threat from a range of pressures with a major one being deteriorating water quality due to pollution from adjacent land use . Rising water temperatures, increasing ocean acidification, Crown of Thorns Starfish (COTS), fishing, and coastal development are also impacting the Great Barrier Reef.
How much is the Great Barrier Reef worth?
Valued at $56 billion, the Great Barrier Reef is a global icon and an important Australian economic, social and environmental asset. It hosts a complex and delicately balanced ecosystem under multiple threats from human activities both locally on the reef, regionally along its coastline and globally through climate change.
How much money did the Australian government spend on land management?
Between 2008 and 2017, the Australian and Queensland governments spent an estimated $600 million on improving land management with the aim of enhancing the quality of water reaching the Great Barrier Reef World Heritage Area (the Reef).
Is the reef resilient?
Many areas of the Reef still show resilience, which presents a window of opportunity to act now, while there is still enough diversity to preserve and restore.
