A case study of "human impact damage" on the Coral reef environment through tourism
Introduction
This case study will take a critical approach to the human impacts on coral reefs in a global context, it will further highlight management strategies and problems that adventure tourism faces in these areas. Further providing a critical analysis of the reasons proposed to explain the popularity of coral reefs.
It is proven that human impacts can homogenize and simplify ecosystems (J. Williams, Gove, Eynaud, Zgliczynski, & Sandin, 2015). With man able to travel to any destination in the world with a click of a button the world’s natural landscapes are being exhausted. This is mainly due to the millions of flocking tourists that seek to feed

This is a major problem that the reef ecosystem faces (Bellwood, Hughes, Folke, & Nyström, 2004). This is no more apparent than in Thailand 's gulf, were the fishing industry is producing about 2, 3 million tons of fish and shellfish in 2007 (FAO …show more content…
This study displayed that "abundances of carnivorous and herbivorous fishes and sea urchins were multiple higher in the protected Ang Thong Marine Park than in tourism-influenced sampling bays of Koh Phangan and Koh Tao" (Pusch, Gabriel, & Wild, 2011, p. 28). In addition, several other studies ran in support of these findings were carried out in various locations such as Hawkins (1993) Sharm El-Shaiq, Egypt, Alcala (1998) Apo Island, Philippines as well as Polunin and Roberts (1993) Netherlands Antilles and Belize. Consequently all showing similar results, in which high fishing and tourism has declined numbers of natural species in comparison to reserve areas, were fishing and tourism is managed or prohibited.
With this research being slightly outdated, as a consequence the impacts founded as result of these studies may be higher or lesser. Management strategies for the reduction in the destruction of coral reefs due to human impacts are numbered, with further advancements in these strategies, there is encouraging signs to show that conservation and preservation is a useful tool and is being implemented in certain regions of the
Problem: Coral Divers Resort is a safe and knowledgeable scuba diving resort with a beach front location. Over the past three years revenues have declined and Greywell suffered a $5, 174 in losses in 1994. Coral Divers Resort needs to do something before business gets worse and Jonathan Greywell and his resort go out of business.
This article discusses how important the organisms symbiotic with coral reefs are, as well as how important coral reefs are to our environment. Also explained is how natural and non natural things things like hurricanes and overfishing affects them. A study is quoted about how water acidity also plays a role in the bleaching of corals. Lastly, restoration and conservation efforts are discussed and how we could possibly help our oceans.
Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people.
A statistic released by the Marine Science Education Project of the Indonesian Ministry of Higher Education States that “…Reefs subject to land-based pollution (sewage, sedimentation, and or industrial pollution) show 30–50% reduced diversity at 3 m, and 40–60% reduced diversity at 10 m depth relative to unpolluted comparison reefs in each region.” This statistic is alarming because it shows just how much pollution can affect a certain environment. Not only does it affect the environment but it also affects animals, plants and people.
Humans are one of the biggest threats to coral reefs around the world. Coral reefs house a diverse mixture of underwater species like sea turtles, hundreds of different fish species and over a thousand species of mollusks. They are home to an incredible amount of wildlife as well as protecting the coastline from ocean storms.
Oceans cover 71% of the earth’s surface. The talk of climate change can often seem to focus on what is happening in our atmosphere, but there is a lot of change going on in our oceans. The oceans have absorbed 90% of the excess heat and 28% of the carbon pollution generated by human consumption of fossil fuels (Nuccitelli 2015). The purpose of this paper is to show how the effects of climate change effect the coral reefs in our oceans, with a focus on the coral reef systems in the Caribbean and of the Great Barrier Reef. The Caribbean coral reefs are well known to have suffered more damage between the two reef systems. That’s not to say that the Great Barrier Reef has not suffered its own damage. It has and will continue to suffer in the future.
Oceans flourish through increased productivity, still, potential exhaustion though extinction is casting out a possible “tragedy of commons”, hook, line, and sinker. From thriving to potential empty oceans; the environmental and human impact on our oceans remains extensive, with over one-half of the world’s fish populations being exploited, according to the United Nations Food and Agriculture Organization (FAO). Additionally, the expected depletion of our ocean species according to scientists within a 2006 scientific journal, predict the total collapse of all oceanic species by the year 2048 (Withgott & Laposata, 2012). Oceanic productivity may have potential toward recovery by assigning no-fish zones and marine reserves. The capability to shift the tides toward replenishing our oceans should also combine monitoring and protecting its productivity by encouraging oceanic reef systems and decreasing over-fishing.
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. The leading natural cause of destruction among the coral reefs is global warming. Other natural causes are earthquakes, hurricanes, cyclones, and typhoons. The destruction to the coral reefs from these natural disasters is minimal compared to the dangers caused by man. Man-made destruction has a much wider impact on the health of the coral reefs. This destruction includes over-fishing, damage from anchors, aquarium industry, overgrowth of seaweed, and being smothered by sediments.
Climate change has been affecting coral reefs in a negative way. If the climate continues to get warmer more of our coral reef become bleached, the structure of the reefs will become weak, and algae that keeps coral healthy will die. In the essay, “A framework for understanding Climate change impacts on Coral Reefs” by Joshua Clinner (2016), he emphasizes our climate change has become one of the long-term threats to coral reef. The article “Climate change and human impacts are damaging the world’s coral reefs”, which didn’t include an author (2001), states that the sea temperatures throughout the tropics has increased dramatically leaving much of the coral unhealthy. Spencer Hall (2008), discussed in his article “Coral Reefs and Climate Change”, how the increase in climate change puts a lot of stress on coral reefs because they are very sensitive to the change of temperature. Rigel B (2003) states in his essay, “Climate Change and Coral Reefs”, that coral reef has already been negatively impacted by
They come in by boat, they come in by plane, they come in on wheelchairs, and some even walking in with canes. Millions of tourists from around the world, most especially Europe, The United States, and Canada find it fit to experience for themselves one of the world’s most exquisite arrangements of islands: The Bahamas. They travel here to get a firsthand look at our way of life: our culture, our striking man-made attractions and our extraordinary natural wonders most especially our tranquil, soothing, turquoise waters. According to the documentary ‘Free Swim’, interviewers discuss the issue of The Bahamas not being able to produce the same amount or more of the conch species today in society as in times past. The film further analyzes how conch plays an important role in our number one industry in The Bahamas: tourism. Therefore, if there is a decline in our conch population, what attraction is left for our tourists to sightsee when they go snorkeling in our waters? What are we going to do if our tourism industry is declining also? To elaborate more into the topic, many reasons are discussed as to why there is a decrease in our conch population and what can we do to preserve it. The Bahamas is currently at its “wits-end” as we have witnessed the queen conch being listed as an attraction that is on the road to extinction. This dilemma is caused by the numerous amount of poachers and some Bahamians who overfish in our waters; harvesting a large number of immature conch. When persons continuously harvest too much of our conch, it decreases t...
Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse. Unfortunately, human impact has resulted in long-term stresses that, unlike the short-term stress of natural disasters, coral reefs are not as capable to recover from. “Approximately half of the world’s coral reef ecosystem resources are considered by scientists to be in 'poor' or 'fair' condition and have declined over time due to several anthropogenic threats” (“Status of Corals” par. 2). Through poorly administered commercial practices, carelessness and ignorance among the common people, and human aggravated natural processes coral reef destruction has become a serious issue afflicting the world’s biodiversity and it’s intricate biosphere mechanics (“Human Impact on the Great Barrier Reef” 1) (“What Are Coral Reefs?” 1).
The establishment of the Marine Park system will provide a place of refuge for marine animals and improve their overall living conditions. This is because marine parks have specific rules preventing the exploitation of species, over-fishing and boating pollution, enabling marine life to become more plentiful and the individual organisms to increase in health and size. The diversity of the organisms will also increase, as will the overall biomass of the sea life. There is proof of this on Rottnest Island, WA. The density of lobsters was ’34 times higher in the sanctuary… than in other areas around the island wh...
Corals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish, 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the foundation of marine life, and this also means that they are essential for human life, but all over the world they are dead or dying because people are destroying them at a very fast rate. Already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 years unless people stop doing what they are doing now – i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.
In conclusion, I would like to say that before writing this paper, I had no idea how important coral reefs were to the earth. I have learned a lot and I think that if more people were informed about the positive capabilities of them, humans wouldn't be so careless about them.
Today many people do not see the need to preserve corals reefs. Hence because of the lack of appreciation for the reefs, they are slowly disappearing. Many citizens do not realize the importance of these reefs, the species they hold, and the food webs that connect the ecosystems. Our American government has stated many times that they are doing all they can to preserve and to replenish our coral reefs. However, how accurate is that statement? To answer these questions, we first have to understand what a coral reef is and how it can be saved.
