Climate change caused by increased levels of atmospheric carbon dioxide has been a front-runner in the global environmental quality debate for years; however, the other side of atmospheric carbon dioxide’s effect on our world - the massive absorption of carbon dioxide by the ocean - has received far less attention. While climate change is a change in global or regional climate patterns attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels, ocean acidification, often called climate change’s “evil twin,” refers to a reduction in the pH of the ocean over an extended time due primarily to the uptake of carbon dioxide from the atmosphere by the ocean. This carbon dioxide influx is a direct consequence …show more content…
Even though the ocean may seem far away from your front door, there are things you can do in your life and in your home that can help to slow ocean acidification and carbon dioxide emissions. Ocean acidification is an environmental problem that affects us globally. Currently, it is impossible to predict exactly how the increased lowering of the pH of our oceans will effect marine food-chains and ecosystems since focus on this particular problem has just begun to increase in the ocean science community. It’s important that this issue becomes a main topic in the ocean science community so we can learn more about what is going on and, therefore, take the needed actions to remedy our mistakes. We do know, however, that at the current pace of ocean acidification we desperately need to make some changes in our world and become more considerate toward our environment, as we are main contributors to the carbon dioxide both in the air and in our oceans. Ultimately, we are putting more carbon dioxide into the atmosphere than can be absorbed by the earth's natural processes, which is leading to this carbon dioxide imbalance and an unsteady state system. Future predictions we do currently have indicate that the oceans will continue to …show more content…
Ocean acidification is an already observable and predictable consequence of increasing atmospheric carbon dioxide concentrations with biological impacts, and will need to be recognized and integrated into the global climate change debate in order to decrease long term damage, at the very least. You can personally help ocean acidification by reducing your individual carbon footprint. Reducing your personal carbon impact includes: carpooling, biking, using public transportation, keeping maintenance up to date on your cars, and using less electricity. It’s also important to support clean renewable energy initiatives in your community and organizations that protect the ocean, like The Alliance for Climate Education (ace) or The Natural Resources Defense Council (NRDC). Finally, one of the most important things you can do is to tell your friends and family about ocean acidification. A lot of people still don't know how the oceans around us are changing; thus, supporting public education about ocean acidification and its effects is very important so we can all understand what we are doing to our oceans before it is too
...oceans. Anthropogenic systems such as the combustion of fossil fuels since the industrial revolution have greatly increased the rate of acidification to levels where negative impacts ensue. Negative impacts occur both to marine organisms that rely on certain water conditions to maintain vital functions and the environment which is damaged by highly acidic waters. There is great variation in the acidity of each of the oceans, differences caused by the chemical composition of the ocean and biogeography. Understanding of the potential impacts of ocean acidification is relatively new to the scientific community and therefore little is known on how to counteract anthropogenic influences. Although reducing the amount of carbon dioxide produced will in turn reduce the lowering of the oceans acidity levels and reduce negative impacts on the environment and marine organisms.
Usually, if there is a problem, there is most likely a solution or something that helps fix the problem a bit. There is so many different ways to help, but i'm only going to give a few. Use public transportation or invest in a electric car or carpool. Buy some non-toxic ecofriendly fertilizer, update sewer and water treatment, recycle as much as possible, cut up the six pack rings, pick up litter, buy products with little to no plastic packaging, don't wear sunscreen, donate to organizations that help the ocean, don't buy products that are harmful to the ocean after use, ect. The ocean is so important to our culture ans society and helps us in many ways, we should keep the ocean as beautiful as it was before we started to pollute
Even though the study of the deterioration of pteropods in high acidity water may seem unimportant in the grand scheme of the ocean, it is crucial to start somewhere. In this case the pteropods happen to be one of the most obvious examples of marine life that will be influenced by the ocean acidification. It is without a doubt clear that ocean acidification is an up and coming problem that will change the chemistry of the ocean and not only the effect the ocean’s ecosystem and creatures, but most likely the rest of the environment as well. Even though there is copious amounts of research available concerning ocean acidification, it is unclear whether model predictions will come to fruition in the future, or if actual results will completely differ from projections. Currently, the only clear path to try to delay the progression of ocean acidification is to reduce carbon dioxide emissions exponentially. The chart below (Fig. 5) gives a concise and detailed account of what is happening, what will happen and what needs to happen if ocean acidification is going to be

One of the major problems affecting, not only oceans around the world, but also many local bodies of water right now is the problem of ocean acidification. You may have heard of ocean acidification, which you may have just disregarded as a problem that affects the large oceans as a whole. However, this acidification also affects the Chesapeake Bay itself. I have come to realize that the acidification of the Chesapeake is a major problem that will affect the diverse ecosystem that all the wildlife is located in, but also the many businesses locally and throughout the state that depend on the health of the ocean and the wildlife located in the
Ocean acidity will spoil marine ecosystems if it remains persistent. Preserving sustainable fishing industries will become unmanageable if the carbon dioxide absorbed by the world’s oceans is not considerably abridged.
Carbon dioxide disturbs ecosystems candidly, both positively and negatively. On land it increases growth in various trees and plants, an influence occasionally called ‘CO2 fertilisation’. Absorption of CO2 into the oceans triggers ‘ocean acidification’, obstructing shell formation by organisms like corals and affecting coral deterioration or
In the atmosphere carbon dioxide is chemically neutral, however when it dissolves in seawater it reacts with H2O to form a weak carbonic acid. Over recent years, oceans have become more acidic because of the increase of carbon dioxide in the atmosphere. The acidity of the ocean is determined by the concentration of hydrogen ions which are then measured on a pH scale – where the greater the level of hydrogen ions, the lower the pH (Askins, 2008). As the pH of the ocean drops from the pre-industrial value of 8.2 to 7.8 by 2020, ocean acidification is predicted to have a great effect on the ocean. Many of the aquatic organisms are very sensitive to the acidity of water, and as a result there will be effects at all levels of the marine food web (Balch & Utgoff, 2009). The carbonate shells of marine animals for example can dissolve in acidic waters. Also coral reefs will also be impacted negatively by increased acidity in addition to the effect that warmer waters are already having on them (McCarty, Wolfenbarger,
Ocean acidification is defined as “…the perturbation to the ocean carbonate system directly caused by ocean uptake of anthropogenic carbon dioxide (CO2) emissions to the atmosphere.” (Turley) Overtime, our oceans have become more acidic due to rapidly evolving technology and a growing dependence on fossil fuel. In fact, our “oceans have become 26% more acidic since the start of the Industrial Revolution.” (Cullinane) Unfortunately, this acidity continues to rise and “…the pH of surface oceans…is projected to drop another 0.3–0.4 pH units by the end of this century, [which] has not occurred for more than 20 million years of Earth's history.” (Guinotte) Why our oceans today so acidic and what can we to control these pH levels?
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
"On a recent afternoon, Scott McKenzie watched torrential rains and a murky tide swallow the street outside his dog-grooming salon. Within minutes, much of this stretch of chic South Beach was flooded ankle-deep in a fetid mix of rain and sea.
Ocean acidification will have harsh outcomes for shelled organisms and coral reefs. But don’t you wonder what type of effect it will have on you! People have a misconception that if the ocean turns into acid that it’ll be hazardous to get in the water. Ocean acidification isn't gonna harm humans directly. As you all know though humans are inextricably linked to the health of the ocean. Ever since i can remember humans have depended on the sea for more things then land. The ocean provides resources like food, recreation, transportation, and medicines. People need to realize they need the ocean for more things then they can imagine. Not to mention the guilt you’d feel if the ocean was extinct and you didn't do anything to help prevent it.
How would the marine animals feel if their home was being destroyed little by little every day because of ocean acidification? Because the amount of carbon dioxide that is in the ocean is rising at a rapid speed level, the marine ecosystem is endangered. The animals that live in the ocean depend on their habitat to live and because of ocean acidification, these animals are losing their home. The main reason that these marine species are losing their home bit by bit is because of the humans. Humans can be the ones responsible for destroying the oceans because we are the ones creating the carbon dioxide emissions every day and those emissions end up going into the ocean. Because the
“If the Earth keeps getting warmer, up to one–fourth of all animals on Earth could become extinct within 100 years” (Global Climate Change). Climate change can be caused by humans or by natural causes. Humans can cause climate change by emitting aerosol pollution into the atmosphere and by burning fossil fuels. Over the years humans have become incredibly selfish and have not been taking care of the Earth like they should be doing. Because of this the temperature of the Earth has been rising and many animals have been getting affected by this.
