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.
The Great Barrier Reef is located in the Coral Sea off the coast of Queensland in Australia and has many creatures living in it. It is the largest coral reef system in the world, and it is so large that

One problem is El Niño, which makes the water hotter than the corals are used to, and hot, still water for long periods of time creates heat stress the corals cannot survive with (Howard). When the water is too warm for the coral’s main food source, algae, it becomes toxic to the coral, resulting in the coral extracting it. When this happens, it gets rid of all color from the coral tissue, leaving behind a transparent skeleton. This process is called bleaching. If the coral goes too long without the algae, it will basically starve itself to death. To keep the corals alive, the change in water temperature must happen quickly (Netburn). This means everyone must do their part or else the Great Barrier Reef’s salvation will be out of reach by …show more content…
The carbon dioxide in the air rises due to fossil fuel emissions; therefore, more of the gas goes into the ocean’s water. That makes the coral’s habitat more acidic, which can make it harder for reef-building creatures to build up the hard skeletons. And if that isn 't bad enough, the runoff chemicals from farms and lawns are adding to the problem by changing the water’s natural composition. A oil spill in 2010, caused by a Chinese coal-carrying ship, went through the coral reef, leaving almost 2 miles of oil to mix with the ocean water (Zimmerman). As more and more water is becoming contaminated with pesticides and chemicals, it is becoming even harder to stop the corals from dying. Thankfully, there are solutions that can help restore the Great Barrier Reef.
Just as there are several causes to the habitat change of the Great Barrier Reef, there are ways to put the progressing depletion to a stop. One effective solution is to cut farm pollution, or at least keep it from the oceans. Using organic fertilizers instead of harmful chemicals can keep the coral’s water fresh from the dangerous pesticides. If everybody follows pesticide regulations and follows the laws, it mill make a difference for the coral reef. With everyone 's help, we can all conserve and replenish the Great Barrier
One major limiting factor could be humans and pollution of the ocean effecting the health of everything in the sea. Temperature is also a huge limiting factor. Coral reefs like the environment to be warm but not too warm, it has to be just right. There is also a need for salt, if salt levels go down in an ocean over a long period of time because of rain or rivers the the coral will die. One last limiting factor is overfishing in the area of the coral reef.
That being said, one would see the importance in preserving the integrity of this structure. Elizabeth Kolbert’s choice to explore the destruction of this massive landmark will surely evoke passion for her subject matter and as a reader had no difficulty depicting her passion. I favor the assumption that other readers will react in a similar manner with the thought that the Great Barrier Reef is in peril. Much of society is only concerned with what affects them personally In chapter seven, she piggybacked with atmospheric scientist Ken Caldeira on One Tree Island to find out learn about ocean acidification and her findings show neither good news nor promise concerning the future of the ocean’s coral reefs. The tone of the chapter is that of death: the balance of coral reef revolves around life and death in its current state.
Introduction: World War 2 was a very significant time in Australia’s history and it was a defining point because it played a large part in shaping the way other countries viewed it. One of these events was the battle of the Coral Sea in 1942. This battle was a triumphant point for the allied forces (Australia and US) as they fought through a number of naval engagements to keep the Japanese from cutting Australia’s supply lines from America. The battle of the Coral Sea was a turning point in the war for multiple reasons such as the major events throughout the battle, the outcome and the measures taken to cause that outcome.
The increase in the changes of climate is affecting the delicate coral reefs. Coral reefs depend on a balanced temperature to thrive. The increased water temperature due to global warming are causing the coral to become bleached. They turn white and die. This also kills the wildlife and algae that live in them.
The cell death leads to the expulsion of the zooxanthellae from the corals, which eventually will lead to coral bleaching. Zooxanthellae give corals their color. Symbiodinium are responsible for the majority of coral’s energy (Berkelmans 2006). A coevolutionary relationship is necessary for coral reefs to thrive. This symbiotic relationship is effective in recycling nutrients and using light (Berkelmans 2006).
Even as the ocean is warming, much of the coral cover will still remain. We will see a rise in sea-level but to a limited extent. Working to adapting and mitigating to these climate changes will prove successful. Efficient land-based conservation efforts and sanctuary management work will be crucial for facing these climate
Recently, because of the downturn of sharks, those coral reefs and seagrass
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.
Reefs are composed of calcium carbonate skeletons that are secreted by corals, which form the foundation of the reef ecosystem. The reef biome is found in tropical and subtropical waters around the world, primarily in shallow, coastal areas. In contrast to the reef biome, the rainforest biome is a terrestrial biome that is characterized by high
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
What is the Great Barrier Reef? The Great Barrier Reef is the largest coral reef system located in Australia, but it is also the largest coral reef system in the entire world. It is home to a massive variety of fish, it is home to over 900 islands, and it is also composed of over two-thousand sub-reefs. The Great Barrier Reef remains under constant distress which can be mostly attributed to increases in atmospheric carbon dioxide levels and tourist activities, these include, but are not limited to: boating through the reef, tropical storms throughout the reef, and the pollutants released all through the reef.
In 2014, the Great Barrier Reef was added to the UNESCO 's Endangered Sites list. Along the coast of Queensland, where the coral reef is, there are many ports located there and oil sludge is constantly being dumped into the ocean. The Great Barrier Reef is in dire need of being restored and protected. Michelle Innis in "Great Barrier Reef Is Not 'in Danger ' but Needs Care, U.N. Experts Say" talks about the Great Barrier Reef being threatened. A
The Great Barrier Reef has and will continue to face countless threats in its lifetime. The reef has survived through millions of disastrous events through the years. The Crown of Thorns Starfish (COTS) is a major threat to the coral reefs which helps destroy the Great Barrier Reef. This threat may be no bigger than a dinner plate, but it is one of the biggest threats to the Great Barrier Reef. Kate Osborne and researchers discovered that Crown of Thorns Starfish were responsible for 36.7% of coral damage, 33.8% caused by storms, 6.5% by disease, 5.6% created by bleaching and 17.4% unknown or multiple causes of the damage to the Great Barrier Reef, as shown in Appendix 1 (The Conversation. 2012).
Good Morning/Afternoon ladies and gentlemen, I’m Sri and I work as a marketing manager at tourism Australia. So today I’ll be promoting the Great Barrier Reef as it is my responsibility to advance and develop the tourism industry (change) So here’s some background information on the reef. The Great Barrier Reef is the world's largest coral reef system composed of around 3,000 individual reefs and 900 islands stretching for over 2,300 kilometres.
I choose this article because I think it’s really cool that we are finding ways to repair the coral reefs. The coral reefs are already in danger of extinction because of global warming, so finding a way to try and repair them is great. Ever since the Industrial revolution, the oceans have been taking in more carbon dioxide. The quantities of the gas taken in by the oceans are large enough that now some areas of the oceans have become more acidic, a phenomenon called ocean acidification. Ocean acidification is harming many groups of animals, including coral reefs.
