The Negative Effects Of Tourism On Coral Reefs

The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.

Tourism in Australia has evolved over the years and continues to increase to this day, however it is the effects that tourists have the ability to place on the Southern Great Barrier Reef which are potentially threatening for, not only the reef of lady Elliot Island, however, the corals surrounding it. “International visitations within Australia alone reached 3.9 million visitors within the first 7 months of 2014, which was an increase of approximately 9.5%, a number which continues to rise” (Tourism Australia, 2015). However, with this increasing number, comes possible damaging effects to the surrounding reefs of Lady Elliot Island, possibly leading to the excessive damage of corals due to activities and infrastructure requirements

"Coral reefs… are fragile structures living within a narrow range of temperature, clarity, salinity and chemistry. Even a slight increase in ocean temperature, or increased CO2… can cause stresses such as bleaching… These stresses slow the rate of growth of the corrals… With some 60 percent of the world’s coral reefs now losing productivity, it’s becoming a global crisis and a scientific mystery."

Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.

Coral reefs are greatly hurt by tourism. When tourism first began, people had little regard for the delicate balance in the reefs. They would often break off parts of the coral to keep as souvenirs, damaging the area and hurting both the corals and the fish or other animals that relied on it. While humans today are more aware of the damage they cause, regular visitations can still create great damage by snorkelers or divers accidentally hitting and damaging the reefs.

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.

Furthermore, extraction of building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and destruction of habitats. Overbuilding and extensive paving of shorelines can result in 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 coastline ecosystems 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

These increasing ocean temperatures, which result in global warming, are mostly due to the amount of CO2 released in the air, therefore threatening the existence of the coral reef systems (Cole, Pratchett and Jones). The reduction of the coral reef ecosystems are attributed to the climate induced bleaching from the past decade. The loss of coral reef environments has direct affects to the habitat of an organism within the reefs (Cole, Pratchett and Jones), leading to a decrease in biodiversity (Coker, Pratchett and Munday).

Conservationists around the world are putting their best foot forward in an attempt to save the coral reefs. Coral reefs today are at a high risk of damage because of all the attention drawn to them by tourists. There are some islands that make all their money through tourism and exploiting the coral reefs, giving snorkel and scuba diving trips to guests that have traveled from around the world. Many people travel to these places with amazing under water worlds and they come extremely uneducated about these beautiful masterpieces. Tourists will drop their anchors on top of corals and drive their boats over corals, causing severe damage that will take the coral years and years to replenish. There are always new ways to enhance the lives of the

The coral reef surveyors were instructed to find the best sites that they believed had the most living coral and were thought to be least affected by human activities. This would allow Hodgson to determine if human activities were having an appreciable effect on the supposed pristine coral reefs, which were distant from urban centers. The invertebrate survey was undertaken at two depth intervals of 3m and 10m. Four 0.5 m wide by 20 m long belts were placed on the coral reef. Over a period of 3-5 minutes the observers counted the number of invertebrates found on the belts. The coral survey was performed, by placing four 20 m long belts on the coral substrate. At 0.5 m intervals the substrate on which the belts were lying was examined and recorded.

Climate change is gradually making the coral and sea life in the reef become warmer, this is due to the sudden rise in greenhouse gasses which is creating a hotter world for us. ‘’The global surface warming trend for 1997–2015 is approximately 0.14°C per decade’’. If this trend continues it will then eventually heat up the ocean too much and then all sea life will slowly die out. ‘’Scientists project a significant loss of biodiversity within a decade, and at worst a 95 percent decrease in the distribution of Great Barrier Reef species by late this century’’. This is what could happen if we don’t find a solution to this

One of the main ways that human’s impact coral reefs that could be avoid is coastal development that produces unsustainable tourism. Today, people are constantly looking for tropical places to vacation and adventure on these tropical islands. Since coral reefs can only be supported in tropical waters, they tend to be located by nice beaches on popular islands. The Caribbean is one of the best examples of this. Countries such as Jamaica and the Dominican Republic are generally poor countries with little development. Over the past years, these islands with tropical waters and coral reefs have began to build more and more resorts

Changes in the environment have had a negative effect on the health of the Great Barrier Reef. Development of coastal areas around the Great Barrier Reef and other land use has hurt the health of the reef. The effect of global warming has altered water temperatures which have killed off algae with which live on the reef and that has led to coral whitening. Contaminated water from farms and surrounding land development has disrupted the pH balance of the water by introducing more acid into the water, which does not allow proper growth. Overfishing can alter the food cycle and change the patterns on how the reef gathers food. Marine scientists are concerned that the Great Barrier Reef is vulnerable to man negative outside

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as

From the above-given data, the results showed that some stressors affected the coral reef communities at the Jakarta and the Thousand Islands. From the results, the human activities along the show have some effect to the reefs around five meters of depth along the inshore, especially within the bay. The ever-increasing inhabitants of the city have resulted in pollution in most of Asia (Baum, Januar, Ferse & Kunzmann, 2015). The PO4 levels have reached 4µM/L while the DIN levels up to 13 µM/L which have been caused by massive land runoff, inadequate treatment of sewage and large-scale agriculture and aquaculture. The water quality has severely changed when compared to oligotrophic and turbid waters where the coral reefs thrive. From the articles, it indicates that ever-increasing human activities along the coastal lines have led to severe changes in the quality of water through pollution. This has, in turn, affected the population of the coral reef.
