Located off the east coast of Australia, the Great Barrier Reef is the world’s largest coral reef. It started growing approximately 20,000 years ago and now extends over an area covering 345,000 square kilometers. It was first discovered by James Cook in 1770 when he struck the Endeavour Reef, which led to the scientific community learning of the existence and extent of the reef (Doubilet). The Great Barrier Reef averages forty feet below the surface of the Coral Sea, and is made up of close to three thousand smaller reefs (De’ath, Fabricius, Sweatman, and Puotinen). Coral reefs are the most diverse marine ecosystems in the world. In fact, approximately a quarter of marine life depends on coral reefs for both shelter and food (“Corals and Coral Reefs”). Surprisingly, coral reefs only make up seven percent of the Great Barrier Reef (Australian Government).
The Great Barrier Reef has a tropical climate that is affected, during the summer, by an equatorial low pressure zone and by a sub-tr...

Port Arthur was Australia’s largest and most notorious prison holding the most vicious and hardened criminals from 1837 to its closure in 1877. The aim of Port Arthur was to produce useful goods and useful citizens, reformed men who have rejected a life of crime and embraced a law-abiding future. It was known for its tough punishment and structure. This essay will discuss the daily life at Port Arthur for convicts, punishments convicts received, trades that were practiced there and the merchandise that was created through those trades and what become of Port Arthur after transportation finished.
In February of 2010, a woman named Dawn Brancheau died while working as an animal trainer at SeaWorld in Orlando, Florida. There has been a large amount of debate about the circumstances surrounding her death—some say she slipped and fell, while others say that she was dragged in by one of the orcas, Tilikum. The controversy over her tragic death brought this question to the surface: should parks like SeaWorld be closed down for safety reasons? While this argument has been going on for a long time, the death of Brancheau spurred a wave of debates about whether the park should be allowed to remain open. On one side, people believe the parks should be shut down and the animals should be released from captivity in an effort to protect the animals and the humans. On the other side of the argument, people believe the parks should be kept open because of the benefits they offer to the world in education and conservation. In light of SeaWorld’s recent transitions, I believe the park should remain open to the public.
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
We need coral reefs, and not just to make the ocean look pretty and colourful, they are more than just that…
I’m Yukina Yasuda. I'm here to ensure you that the great barrier reef is best icon for Australia.
The Great Barrier Reef is one of the most fragile ecosystems in the world, it protects coastlines from the dangerous effects of tropical storms and wave action, it is also home to more than 11,ooo marine life. It is one of the world’s largest coral reefs, so large in fact that you can see if from space.
The numerous micro habitats of coral reefs and the high biological productivity support a great diversity of life. The Great Barrier Reef The Great Barrier Reef is a chain of coral reefs in the Coral Sea, off the northeastern coast of Australia. The largest reef in the world, it extends about 1250 mi from Mackay, Queensland to the Torres Strait (between Australia and New Guinea.) The Great Barrier Reef is home to a remarkable number of organisms.
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.
The Great Barrier Reef is an exemplary model of the famous exotic coral reef seen in a copy of the National Geographic or the popular animated film Finding Nemo. Located on the coast of Australia, it is known as the “largest biological organism in the world” (“Human Impact on the Great Barrier Reef” par. 1). The idea bears that coral reefs are again not an assortment of organisms functioning separately but rather working together to thrive. The groups of coral that are seen in t...
The Great barrier reef has had many recent hardships, including water pollutants and the increasing water temperature. Although it may be too late to save this particular reef we the people must not be so nearsighted to the
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
There are about 70% of our earth is covered by water, and people just know a little part of it now. Underwater tourism is an excitement and adventure, and it is also a special tourism concept. The undersea world attracts people to explore the mysterious of the ocean, and the underwater tourism is growing very fast basic on the new technology. Travelers can join this tourism by many different methods, such as underwater restaurant, underwater hotel and underwater activity. There are many travelers will try to have the experience of underwater tourism and spend a lots of many for that. Travelers
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.
