Coral reef destruction
Last year, scientists remarked the "unprecedented" collapse of Florida's reef, that expands along the south-eastern part of the state of Florida. This ecosysten, that was the only barrier reef in the continental US, was attacked by bleaching in 2014 and 2015 and is now is "beginning to dissolve away", according to Chris Langdon, a coral expert at the University of Miami. More than 80% of shallow water reefs of Christmas Island have died and it has been shown by pictures released to the public not too long ago, that 90% of the reefs in Okinawa, Japan were bleached as well. This is an alarming news, not only because it will affect marine life's ecosystems, but us as well.
The most common phenomenon we've seen thus far has been the bleaching event. Bleaching is a process that happens when waters are too warm; the corals will expel algae that is living inside them causing the oral to become

Loss of coral reefs would be devastating to one of the most grand pools of biodiversity in the whole world They help seed the oceans and provide food to a complex web of organisms that lead all the way to man. They act as natural barriers to shorelines, and as they die, coastlines become more susceptible to damage and flooding; tropical storms and high waves would be the ones that could make the most damage if coral reefs were to disappear. Of course, not only we are the ones to be damaged by this, but other animals in the marine ecosystem too, like sharks. Sharks work in the ocean and in coral reefs by cycling nutrients between it and the open ocean, removing invasive species, and getting rid of weak fish carrying disease; if coral reefs were to disappear, then sharks would lose one of their main ways to obtain food and nutrients. And as we all know, if one animal disappears in an ecosystem, the organisms that consumed them would die and affect the food chain so
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.
1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing.
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
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.
When a certain species is removed from their ecosystem, it can have effects on their prey and their predators. Their prey’s population would increase, and their predator’s population would decrease due to their being nothing for it to eat.
Rough Draft #1 Battle of the Coral Sea was an air and naval engagement between the U.S. fleet and Japanese invasion force. “It was the world’s first all-carrier battle, and the first sea battle which neither side could see each other” (Pacific Aviation). The Battle of the Coral Sea helped the Battle of Midway (occurred on the following month)by destroying 2 Japanese carrier ships (Shokaku and Zuikaku.) The battle thwarted the invasion of Port Moresby to July 3 1942 (until the Battle of Midway settle the invasion). Japanese forces had been planning to invade Port Moresby in New Guinea.
Oceans are peaceful, majestic, and filled with amazing and vibrant color. A lot of the prostown beauty in oceans can be credited to coral reefs. Lately though, natural coral reefs have been dying for various reasons, and some people believe that artificial reefs can help not only the natural reefs, but other surrounding ecosystems in their environment. Various articles use rhetorical techniques in hopes of enhancing their articles about whether or not artificial reefs are helping or harming the oceans. The first article, “Concern Lingers on Success of Artificial Reefs”, was written by Charles Q. Choi, and for Live Science, looks at both the pro and con side of artificial reefs.
Ocean Acidification is a pressing issue that will have a major effect on the ocean in the near future. According to the National Oceanic and Atmospheric Administration (NOAA), ocean acidification is when the pH drops due to an uptake of atmospheric carbon dioxide. This is a controversial issue because many people do not believe the ocean is becoming acidic. They believe ocean acidification is a hoax brought on by global warming to try and convince people on the dangers of climate change. This issue is important because ocean acidification posses a threat on the coral reef ecosystems, which house 25% of marine, fish species.
If sharks go extinct it can cause a disastrous effect on the food chain; coral reefs could possibly die and fisheries could collapse. Keeping sharks alive helps keep a healthy and regular balance in marine life. The oceans
Despite animals bring a superior capability to adjust what happens over plants do, they might also die. When the animals and plants die, the public loses two sources of food, plant nourishment and animal nourishment. They might additionally lose their homes. Hence as an result, they might take off those region or die. This would be called a breakage in the food chain, ultimately one thing leads to another thing and so on and so forth.
Since, the increasing popularity of scuba diving has put more strain on coral reefs around the world. In fact, specially the driver work underwater photographers and beginners sometime make contact with fragile corals, breaking them or damaging them and leaving them susceptible to bacterial attack and disease. Eventhough they are not colleting illegal of coral reef still that they did not be responsibility to what they have done with coral reef. Occasionally, all the souvenirs are made from marine life for instances polished shells, clams and nautilus shells, jewelry made from shell or tortoise shell, pictures with dried seahorses, ashtrays made from clams (Teresa Zubi, 2015).
