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 coral reefs were to be removed from the ocean, fish would no longer have a place to live and have babies. According …show more content…
Ocean acidification is caused by the uptake in atmospheric CO2. Through the burning of fossil fuels and the excess use of energy on a daily basis, humans contribute to the rising levels of carbon dioxide in the atmosphere. I want to talk about how through human means; ocean acidification is destroying the oceans coral reef ecosystems, which ultimately affects the algae and fishes in the ocean and humans source of food. I understand what ocean acidification means chemically and biologically for the ocean and what its affects are. Coral reefs make their shell with the calcium carbonate ions in the ocean but if the ocean becomes more acidic, there will be less calcium carbonate in the ocean. Coral reefs have natural threats of bioeroders who eat through corals calcium carbonate shell, so if corals cannot build their shells faster than bioeroders can eat them, corals will die. This is one major example of how a more acidic ocean will be detrimental. I have consulted articles from the journal Oceanus and from NOAA. Both of these sources publish professionals in the field of marine biology and chemistry. These sources along with general classes I have been taking have helped me and will help me better understand this pressing …show more content…
Having an ocean without coral reefs is almost like having a world without homes. There would be no place for shelter or to raise a family and humans would be more susceptible death. When in a chemistry lab, if one were to add just a little too much of a chemical, the whole reaction could be changed. For chemical reactions to work properly, there cannot be excess amounts of certain chemicals because the balance would be thrown off. This is exactly the same for the ocean; when the ocean absorbs more CO2 than normal, chemical balance is thrown off. Although in certain parts of the world there are thriving coral reefs in more acidic water, these reefs were made to live in these harsh environments, but if in a couple hundred years the pH level drops even more, those reefs may too die like the rest. Ocean acidification is a pressing issue that needs to be dealt with now before it is too late to save the
If the climate continues to rise the coral population could become obsolete and disappear (CREARY, M. (2013). One of the most notable climate changes that damaged the coral reefs was the “El Nino” storm in 1998. This storm caused an extreme increase in the water temperature and bleached one- sixth of the corals in the World (El Niño prolongs longest global coral bleaching event. (n.d.)) Although we cannot prevent the weather, humans can reduce the amount of deforestation in rainforests that will reduce the amount of carbon dioxide that is emitted into the atmosphere.
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.
Background: In Ischia Island the water around the island has been acidified for millions of years because of Mt. Vesuvius. This dormant volcano is melting chalk in the sea floor, which releases carbon dioxide into the water acidifying it. This acidification is devastating the life around the island and is still being acidified by the continuous release of CO2. We can use this as an example of what our world might look like if we continue to release carbon dioxide emissions through things such as burning fossil fuels and reducing the carbon banks such by things like deforestation.
Castello Argonese, a tiny island in the Tyrrhenian Sea gives us an enlightening glimpse of Earth in 2100. Chapter six of the book The Sixth Extinction by Elizabeth Kolbert, is solely devoted to her experience in these waters where the vents on the sea floor bubbled up almost 100% carbon dioxide. She talks about the consequences of constantly burning fossil fuels to add about 365 billion metric tons of carbon into the atmosphere and how it could lead to our own demise. The thing about carbon dioxide is that the moment it interacts with water, it becomes an acid which can be deadly to the animals living in these oceans obviously, but also to organisms above sea which includes humans. Elizabeth Kolbert wants us to understand that our actions have tragic consequences and we too will be part of that tragedy if we don’t stop now.
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
Climate changes caused by ocean acidification will not only affect animals and plants, but will have an impact on our surroundings. Global climate change threatens coastlines and the buildings and cities located along them. Many people around the world live in low–lying areas near the coast that could be flooded as the sea level rises. If something is not done to prevent excess carbon dioxide, it will leave lasting
There are two proven cause of ocean acidification. The primary cause is the increased in amount of atmospheric carbon dioxide. Presently, the ocean adsorbs approximately one third of the anthropogenic carbon dioxide (National Geography), which when dissolved in water, produce carbonic acid and hydrogen ions. The other cause is additional pollutant that enter the ocean. When
According to Ocean Science, the ocean serves as a reservoir for carbon (Hoffman, 161). This is significant because carbon in the Earth’s atmosphere is at an all-time high due to humans burning fossil fuels and increase in deforestation leading to fewer trees emitting oxygen in place of carbon dioxide. Excess amounts of carbon leads to acidification forming, and the acid in the ocean is impacting both fish and coral that have lived in the ocean for millions of years. The acid in the ocean is impacting both fish and coral that have lived in the sea for millions of years. The Ocean Portal Team writes, “a small change in the pH of seawater can have harmful effects on marine life, impacting chemical communication, reproduction, and growth” (p. 7).
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.
Around 150 years ago, humans started releasing fossil fuels into the atmosphere during the industrial revolution. The ocean takes up a quarter of the gas that surrounds earth by absorbing the CO2 we put in our atmosphere. Scientist thought the ocean was a great resource for getting rid of these CO2 gases in the atmosphere; however, they didn’t know how much these gases where destroying our great ocean. NOVA’s documentary presents, Lethal Seas, a documentary of the destruction of our vast ocean, concentrating on the American northwest coast, Papua New Guinea among the volcanic islands of Milne Bay, and Aurora Australis. The documentary dresses the issue of rising acidity levels in the ocean and its effects.
When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
Why are experts concerned? Coral reefs are delicate. Overfishing and pollution can harm them. They can also be affected by changes in water temperature caused by occurrences like global warming. What Are Reefs?
“Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system” (Lamm) It may seem very overwhelming on where we should start to help our environment since it seems like such a big task. One small place that we can start is with helping our bleached coral which can help the whole state of our
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
