Coral bleaching is not just a national problem that Australia faces alone. In the last year (2015), 12 percent of the world’s coral reefs have bleached (Howard). Since the Great Barrier Reef is the world’s largest reef, covering 133,000 square miles, and stretching 1,200 miles along the coast of Australia, it poses an incredible threat to Australia’s economy and environment (Howard). Coral bleaching is not an issue that is often plastered all over the news or brought to people’s attention often. Coral Reefs, especially the Great Barrier Reef are seen as the perfect tourist destination because reefs are known for their wide variety of marine life and beautiful bright corals one would see on brochures. However, when a coral is bleached, it loses
The Great Barrier Reef in Australia is one of the seven natural wonders of the world, but massive coral bleaching has stripped the corals of their natural beauty. Less than 50% of the original reef remains. Pollution, habitat change, and global warming is causing the colorful reef to turn a pale grey color. The Great Barrier Reef needs all the attention it can get to restore itself back to its original liveliness. The world-famous coral reef is not only in grave danger, but each day, it is getting closer and closer to complete destruction.
Discussions and Findings What impact are chemicals currently having on Corals and fish species on the Great Barrier Reef? The impacts of chemicals on the Great Barrier Reef are far beyond what is first expected. The reef is subject to effects of sediment, nutrients and chemical pollutants that currently effect 25% of the worlds coral reefs (Amelia S. Wenger, 2015), including the Great Barrier Reef. These three effects result in a decline in water quality, which is due to an increase in nutrients caused by fertilisers, herbicides, insecticides and sewage.
A food web consists of all food chains of an ecosystem. A food web is a diagram which shows the transfer of energy between species. Energy is transferred through food; therefore, food webs basically show which fauna eats which. Food webs are organized into layers of who eats who called trophic levels. The bottom trophic level of a food web is the producers, the second being the primary consumer, then the secondary consumers, tertiary consumers and the final trophic level being the decomposers. The ecosystem of the Great Barrier Reef is a fragile balance, with a food chain that has several points, in which each one is reliant on one another. The Great Barrier Reef’s coordinates are 18.2871° S, 147.6992° E. The Reef has a huge amount of flora
Pollution, tourism, and mining have all had a huge negative impact on the reef. Coral reefs in the Caribbean have also been significantly affected by human interaction due to the growth of population and more people living closer to the reef. This is causing many impacts such as loss of fish and coral etc. Coral reefs in the Caribbean are slowly disintegrating due to coastal development which increases fishing, pollution, agriculture use and
Research Paper Over the past couple years the Great Barrier Reef, off the coast of Australia has had a tremendous bleaching event which has affected the coral reefs and marine life. Around the 1990’s to present time scientists that live in the United States have travelled to the coast of Australia to find out why global warming is happening in these areas. This reef is one of the natural wonders being uniquely seen from the Earth's orbit. The rising temperatures in of the water has impacted about 1,400 miles of ecosystem including marine life and coral reefs.
5 Destruction of the Great Barrier Reef Now it is apparent that the Great Barrier Reef is a fragile ecosystem as it is an interaction of these easily changeable factors, which brings us to the threats with which the Great Barrier Reef has to deal. 5.1 Natural destruction: Crown-of-thorns starfish It seems that every animal in the world acts as a source of food for other animals; this is also true for corals. The crown-of-thorns starfish, which has 21 thorny arms and a length of 80 cm, feeds on corals, coral polyps, and coral algae.
When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
Temperatures reaching highs of 30 degrees Celsius, we expected nothing less, summers have been getting unbearable and winters are nothing to what they used to be. Today started with a warm, gentle breeze with off and on rainfalls this type of weather was typical.
Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
One of the primary motivations to advertise itself as a destination for tourism is the likely economic boost in a developing country. The powerful economic forces provide employment, foreign exchange, income and tax revenue. One of the common economic impacts of tourism is the Multiplier Concept where good or service purchases from the tourist are gain by the Sterling Bay. The earning is then spent again by Sterling Bay to provide a better goods and services for better value.
Some coastal habitats may disappear if organisms are unable to migrate inland because of topography or human infrastructure. This is expected to affect shorebirds and small forage fish, among other species. Warmer waters in regional estuaries, including Puget Sound, may contribute to an increase in harmful algal blooms, which could result in beach closures and declines in recreational shellfish harvests. Ocean acidification is also expected to negatively impact important economic species, including oysters and Pacific
Research has shown that sunscreen is having a negeative impact on the health of coral reefs. Trash is dumped and left on beaches daily. Oil spills and boat use disrupt fish and marine life. Erosion has become a big consern for the stability of beaches.
The algae washes up on shores and destroy the beautiful of the beaches. This also has a side effect on the economy. A nuclear power plant had to be shut down from the algae problem which has cost them hundreds of thousands of dollars per day.
Similar to the Choi, Naik’s article is written with complex sentences that are long and are introduced, elaborated on, and concluded. Plus, the article by Naik is written objectively and in third person, which means that the authors opinions and personal thoughts weren’t given; the information given is unbiased despite the fact it is favored for artificial reefs, but the article mentions the opposing side. Even though “From Balls of Concrete To Habitats for Sea Life” is for artificial reefs and believes they are helping the environment, there is no biased information or opinions given. Unlike Choi and Naik’s article, “The Disadvantages of Artificial Coral Reefs” has an informal tone due to the simple sentences that have watered down ideas that don’t expand on their ideas. However, this article was written in third person, like the other two articles.
