...Great Barrier Reef loses half its coral in less than 30 years The Great Barrier Reef has lost half of its coral cover in the last 27 years, according to a new study released today in the Proceedings of the National Academy of Sciences (PNAS). Based on over 2,000 surveys from 1985 to this year the study links the alarming loss to three impacts: tropical cyclone damage, outbreaks crown-of-thorns starfish that devour corals, and coral bleaching. "We can't stop the storms, and ocean warming (the primary cause of coral bleaching) is one of the critical impacts of the global climate change. However, we can act to reduce the impact of crown of thorns," says John Gunn, the head of the Australian Institute of Marine Science (AIMS), which conducted the research. Crown-of-thorns starfish (Acanthaster planci), the world's second largest seastar and a renowned predator of coral, have seen several outbreaks in the Great Barrier Reef during the past few decades. Outbreaks of the coral-chomping invertebrates are believed to have increased from one every 50-80 years to one every 15 years, which scientists have linked in part to fertilizer and chemical runoff from the mainland. In total, the researchers found that 42 percent of coral loss could be linked the crown-of-thorns outbreaks, 48 percent to tropical cyclones, and 10 percent to coral bleaching. The annual loss of coral cover has sped up as well, averaging 1.45 percent annually since 2006. This pummeling, occurring too quickly for...

...playground of the tourists who are mainly from more affluent ones. In many such nations, the influx of mainly western tourists has brought the problems, such as prostitution as well as alcoholism and drug abuse. Admittedly international tourism does have the potential to foster greater understanding and tolerance between people who are from different countries with different cultural background. however, this is unlikely to occur while it remains such a potent symptom of western cultural domination and moral decadence The even more disturbing, though, is the environmental degradation that international tourism has cause in many parts of the world. A particular good example of this is the Great Barrier Reef in Australia - the countless boats, divers and snorkelers that have visited the reef over the past few decades have gradually destroyed vast section of coral. Similarly, world renowned Kuta Beach in Bali has become heavily polluted in recent years. In order to be sustainable, greater regulation of global tourism is required. In conclusion, the challenges presented by the booming international tourist industry are numerous and complex. Although they are by no means insurmountable, it’s highly unlikey that they will be resolved in the foreseeable...

...named global ecosystem – 15 Coral Reefs are a unique ecosystem, which usually grow in conditions where the temperate is around 24c and in less than 25m depth of water. Coral reefs are homes to over 25% of known sea creatures and are an invaluable service for the local population as a source of food and income. Coral Reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair. A global threat, which is affecting all fragile ecosystems, including coral reefs, is global warming. Firstly, the average increase in global temperatures is leading to an increased rate of ice cap melting. The melting of the ice caps releases more fresh water into the oceans, reducing salinity. The increased water volume is also increasing sea level rise; coral reefs find it difficult to survive in over 27m depth of water. The increase in sea temperatures can also change the nutrient flow. Coral bleaching is a devastating side effect of global warming which affects the corals. Coral bleaching is permanent damage and is occurring globally. The effects of the bleaching are worsened during El Nino years; in 1990 almost 50% of the worlds coral reefs were severely damaged. The most damaged reefs were in the Persian Gulf where 65% had been destroyed, followed by reefs in South Asia where 45% and 38% respectively, were considered destroyed. The Great Barrier Reef in Australia also witnessed a bleaching...

...Oil Spill Environmental Diaster Thursday, April 29, 2010. The massive oil spill off the gulf coast is an environmental disaster. Since it was an oil rig that blew, the oil is leaking from an underwater well, deep in the ocean. It has been hard to calculate how much oil continues to leak, but today it appears to be leaking at the rate of 5,000 barrels a day, not 1,000 as had been thought, and that the spill could reach the coast by Friday. And they don’t have a way to stop the leaking. This is different that the oil that leaked from a grounded ship over the coral reef in Australia this month. That was terrible due to the damage it did to the endangered (and supposedly protected) Great Barrier Reef. But the ship had a limited amount of oil. Since this is a well that is leaking, it seems as if the oil leak could go on and on until they find a way to cap the well. The oil slick is over 80 miles across. The coasts of Louisiana, Mississippi, Alabama, and Florida are preparing for the oil to reach the shore line by as early as Friday. The military has been asked to help, and the Coast Guard are trying to burn the oil in the sea before it comes to the shoreline. Whew! The money made by the oil production could be off set by the loss of income by tourism to these coastal areas. The tension that exists between protecting our environment and increasing our energy sources like oil, coal, and nuclear power, seems to be very problematic. I hope they figure out a way to control this leak....

...has put the Great Barrier Reef into risk. It is observed to have reached the point where the possibility of it being listed in World Heritage in Danger list is greater. Words are delivered effectively by the government in working on protecting the reef however actions are of another way around. Thus, in June final decision on classifying the reef under the “Danger” list will be done by the UNESCO’s World Heritage Committee meeting up in Doha, Qatar. Significant improvement is anticipated otherwise the reef will be officially known for the damaged condition. Such situation shaped due to the failure in fulfilling seven recommendations upon the Committee’s request. Apart from the embarrassment the nation and the people need to bear, Australia tourism industry will be at stake as the reef is one of the best attraction in Australia. Review and Discussion. UNESCO, the United Nations (UN) agency that inculcates education, communication, and arts serves its purpose to conserve and preserve the world heritage. In 1981, the Great Barrier Reef was selected as World Heritage (Australian Government- Department of the Environment: Great Barrier Reef Has Lost Half Its Corals Since 1985, New Study Says, n.d).

NEXT SLIDE What is a brand slogan? “A Slogan is a short phrase that communicates descriptive or persuasive information about a brand” NEXT SLIDE Slogans are particularly important when it comes to differentiating a destination from its competitors. A destination slogan should be memorable and it should tie in with the overall positioning of the brand. Slogans can be an incredibly effective tool and when used correctly consumers will be able to identify a destination and its brand from the slogan. NEXT SLIDE This image is a really great way to illustrate the importance of a Slogan. Slogans are a shadow for the brand, they should be memorable, they should make the consumer want to take action, they should build relationships with the consumer, they should be elaborative and they need to be predictable, something simple that consumers will automatically relate to the brand More often than not brand slogans fall short, they aren’t memorable and they don’t link the audience to the destination. In saying that...

...Introduction The Great Barrier Reef (GBR) in Australia and The Tubbataha Reef (TR) in the Philippines are two renowned reef systems in the world. These reefs are vital to both the environment and the people who live near it, either by providing a habitat for fish, food source for communities, or tourism and other income sources. However, both of these face a great threat to their survival, this threat is coral bleaching. Coral bleaching is a growing issue for most reefs around the world, this is when coral turn white, or bleach, as they either die or become dormant. To try and manage this, governments initiate laws and restrictions to save the reef, yet people still continue to damage it both intentionally and unintentionally. Issue to Reef’s coral bleaching is the issue The issue to reefs is the human induced climate change that causes the water temperature and ocean acidification to rise. These cause the coral to be unable to live so it releases a substance called zooxanthellae, the substance which gives the coral colour, leaving the coral with a ‘bleached’ look. Another factor for coral bleaching is ocean acidification, this is when the ocean absorbs carbon dioxide from the atmosphere. The ocean has already absorbed 1/3 of the carbon dioxide and ½ of the fossil fuels from factories and other human activities....

According to the underwater researcher,“Guillermo de Anda”comments that the cave itself brings out the most important humans in the early age and what they have left behind and the the first settlers of America. Why do we need to know this kind of Information? This kind of information is letting us appreciate more of the world and how we haven’t seen so many different places so explorers will continue traveling to to places and find new things.It also allows us to appreciate much more clearly how the rituals, the pilgrimage sites and ultimately the great pre-Hispanic settlements that we know emerged. This information explains how a few divers went down and found a really long cave that turns out to be the longest underwater cave. It's also an important archaeological find that could reveal lost secrets of the ancient Mayan Relics. This kind of information is letting us see more of the world and how we haven’t seen so many different places so explorers will continue traveling to to places and find new things. It also allows us to appreciate much more about the pilgrimage and the pre-hispanic settlements. The world’s largest underwater cave in Mexico contains Mayan Relics.

...Acanthaster planci, commonly known as the crown-of-thorns starfish, is one of the largest starfish in the world. Yet, what makes A. planci unique is not just the fact that it is large, but the fact that it has an interesting diet. In particular, A. planci enjoys feeding on the coral reefs that dot the Pacific and Indian Oceans. This in and of itself wouldn’t be very interesting, except for the fact that A. planci is an incredibly efficient predator. In the late 1960’s up to ninety percent of the corals in affected areas off the coast of Guam were completely destroyed by A. planci predation (Colgan 1987). Some adult crown-of-thorns starfish can consume up to one metre squared per month of living corals (Chesher 1969)! A. planci also has a few interesting evolutionary adaptations, including venomous spines and a feeding method that includes everting its stomach through its mouth to digest prey (Ault et al 2011). Fascinatingly, A. planci has a very strange method of sexual reproduction that is based on spawning. Finally, A. planci has been the subject of intensive study over the last few decades, yet we still have no real idea as to what causes major infestations of A. planci, and we have barely any idea of how to control them. In this paper, we plan to spread some light on the life cycle, reproduction, feeding habits, predators, potential human causes, and human impacts of this obscure starfish. The appearance of the crown-of-thorns starfish is characterized by a purplish-blue...

...Using examples, assess the relative importance of human and physical factors in influencing levels of biodiversity (15) Both physical and human factors influence biodiversity. On a global scale, climatic and soil fertility influences affect levels of biodiversity, although often human factors influence biodiversity at a local scale and increasingly globally. Biomes and large scale ecosystems such as coral reefs are influenced by limiting factors such as salinity of water which should remain constant, temperatures between 25 and 29 degrees C and adequate sunlight so turbidity level are low. The Great Barrier reef is home to 5,000 species of molluscs, 1,800 species of fish, 125 species of sharks. The age and size of an ecosystem is important in supporting high levels of biodiversity. On the island of Borneo, a biodiversity hotspot, has a number of endemic species and sustains high levels of biodiversity as there is range of altitudes supporting different niches and the size of the area supports many predators. At the local scale, threats from human activity such as deforestation can severely influence biodiversity levels. In Borneo, pristine rainforest was removed for timber and mineral exploitation and the result was a wasteland of yellow grass with low biodiversity. However, human factors can also benefit biodiversity as replanting of native species fertilized by cow urine has subsequently increased biodiversity in the area and the area has been designated an...

Traditional management strategies have been a vast help over the past thousands of year but the severity of human impacts have dramatically increased in the past 50 years and contemporary strategies have been put into practise in attempt to reduce these. While the Great Barrier Reef stands as a beautiful testament to the power of natural construction, in recent years there have emerged numerous threats to the existence of the reef that loom and make its future fairly uncertain which is mainly due to the influence of man.
