An unprejudiced observer might well be fearful that in the not too distant future our children may be able to learn about the coral reefs only from books and documentary films, for one of nature's most unique habitats will have vanished from the face of the Earth. (Patrick White 1957)
The Great Barrier Reef is said to be the jewel of Australia. However Australian lifestyles have had a significant impact on the reef since European settlers first arrived. This essay will discuss two of the major problems the reef is subject to, and the strategies in place to secure the reefs future. Australian lifestyles and farming occur predominantly on the coast, which subject’s the reef to large quantities of sediment runoff. In addition to this problem is the outbreak of the crown of thorn starfish. However, significant efforts are being made to address these problems. Equally important is climate change and the threat it has on the reef in coming years. Consequently, the Government and other organizations have been looking at ways to increase the reef's resilience, to better cope with this problem. On the whole, much is being done to benefit the reef. However, with the increasing threat of climate change, there is still a great deal that needs to be done to secure the reefs future.
Costal runoff has a detrimental impact on the Great Barrier Reef, as well as other problems which are associated with it. Since the arrival of European settlers, farm practices have changed dramatically. We now have approximately 12 million tonnes of sediment per year, run out to the sea due to coastal runoff. This is a result of forestry operations, land clearing for agriculture, grazing and cropping in river zones (Lindenmayer 2007, p47). Sediment can smother a c...

...e affecting the reef. Nevertheless, there are practices being put in place to increase the reefs future resilience. Overall, it would seem that farming practices operating so close to the coast need to be closely monitored as to minimize the amounts of herbicides, pesticides and sediment that flow onto the reef, which also have an impact on the crown of thorn starfish. On the other hand, the reefs long term problem is climate change. Although, this is not just a local problem that affects the reef, but a global threat. However, industries operating off the reef have been taking actions to reduce their carbon footprint. Even though a lot is being done for the resilience of the reef, there is still a lot needed to be done to guarantee the reef future. So in the hope our children don’t have to learn about the Great Barrier reef in text books, and through television.
Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.
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.

There are many actions we can take to help the great barrier reef survive, such us using different means of transport like walking or biking, which decreases pollutions like oils and gas, also reducing the use of plastic bottles, straws and containers will also help, as well as volunteering at a beach cleanup events.
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
Around the world, their are beautiful places called “the seven wonders of the natural world”. These sites are fantastic because of there fascinating views and the fact that they were naturally made, not by humans. One of these seven natural wonders of the natural world is the Great Barrier Reef. The Great Barrier Reef is located off the coast of Queensland, Australia. The Great Barrier Reef was formed by corals growing on submerged islands. The sea level then continued to rise, “leading to more corals growing and forming.” (Zimmerman). The Great Barrier Reef is “a mosaic of 2,900 individual reefs” and can be “seen from space and is not only the world's largest coral reef system but also the largest structure
Another point explicitly stated in the film was that corals didn’t really have a life expectancy. However, because of climate change, they die early. It was discovered that some corals were turning white after six months which is definitely fatal to our planet because we may witness the eradication of an entire ecosystem in our lifespan as said by Doctor Ruth Gates. In addition to this, there is a big heat wave travelling near the planet which leaves dead corals in its trail and in 25 years, all of the world’s corals wouldn’t be able to keep up with this heat and they will all eventually
Climate change and Global Warming are out of control. This means that, no matter what policies, processes or actions are implemented, the Earth as we know it will never be the same again. There is significant evidence to support this hypothesis. The dilemma becomes whether we can limit the damage and adapt to a new status quo or not. Rising sea levels and the damage caused by this phenomenon has irreversible impacts on coastlines worldwide. Damage to sensitive reef systems cannot be fixed. This also has permanent impacts of the ecology not just of those immediate areas but also the ocean as a whole.
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 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
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...
We need coral reefs, and not just to make the ocean look pretty and colourful, they are more than just that…
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.
