Introduction
The oceans of the earth are a massive part of the natural cycles that make this planet habitable. They regulate global temperatures, absorb carbon dioxide, provide a home for millions of plants and animals that make up various levels of the food chain, and so much more. They are a resource given for us to use and benefit from, however, it is also a resource that needs to be protected. It is the fountain of life for the planet and drastic changes to the makeup of the oceans could be detrimental to life as we know it. Ocean acidification is a problem which has come to light in the last decade, but is becoming increasingly concerning to many scientists (1). In this essay I will attempt to direct your attention to some of the possible and observed impacts of global ocean acidification, present some of the likely causes and suggest possible solutions to the problem. The essay will also deal with the possibility that the evidence can be interpreted differently in order to not implicate humans as the primary cause responsible for the observed destruction occurring in the acidified waters.
Defining Ocean Acidification
Ocean acidification is when carbon dioxide is absorbed into the water of the oceans. This causes a chain of chemical reactions leading to the formation of carbonic acid in the water. (2) Furthermore, many animals in the oceans use calcium carbonate ions to build their shells, however, in the process of forming carbonic acid, these ions are destroyed creating a deficiency in calcium carbonate and preventing these animals from forming their life sustaining and protective shells. (1) The reaction occurs when carbon dioxide, which is heavier than air, sinks in large clouds over the oceans and is absorbed into th...

...gain recognition both by environmental organizations and governments, but also by individuals who need to be aware of the impact their actions and energy usages. Whether it be a new form of energy or an old one refined, continued research and work needs to be done to ensure that we are being good stewards of the earth we have been given to live on.

The bubbling pool of acid: Acidification most disastrous event in the history of our planet
...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.
As certain types of pollution damages our atmosphere, our natural protection from the sun weakens and as a result the Earth gets warmer with time, impacting the temperature of our seas. The unfortunate results of global warming and the co...
Given how important coral reefs are, the increasingly disappearance of our coral reef ecosystems will continue to have a detrimental impact on marine biodiversity with in these ecosystems. In addition to the decline of the animal species, job opportunities for many staff members that keep our parks open and healthy for everyone to enjoy, revenue be lost due to the decline in coral reefs. To help ensure this downward spiral in eliminated before it is too late, park officials and scientist conduct continuous research on the effects of ocean acidification and global warming on marine organisms and overall health and longevity of these ecosystems. Ultimately, the goal is to develop ways to intervene before it is to late in hopes that we can reverse the damage already inflicted on our coral reefs and allow these ecosystems to re grow once
With carbon dioxide levels continuing to rise over the past few decades (fig. 1) and now into the future, concern has been brought to what is happening to the carbonate chemistry of the oceans. Because of these changes in chemistry, the ocean is becoming more acidic. Along with climate change, ocean acidification may be one of the greatest threats to our planet. The higher the ocean’s acidity level goes, the lower the calcium carbonate levels will drop. Even though this is a big scale issue, my goal is to focus on and underline what these changes will mean for the marine life that depend on the calcium carbonate in seawater. I will go in depth with specific regards to a study regarding pteropods or sea butterflies.
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
is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere

The Earth’s biosphere is being affected by climate change in numerous ways. The interactions that occur between the hydrosphere and atmosphere are leading to changes in our ocean’s chemistry that could be devastating to humans in the future generations to come. Climate change is the modification in the climate patterns. The effects of climate change have become particularly apparent from the mid to late 20th century onwards and have been substantially contributed to by the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
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.
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
In “Chapter 6 – The Sea Around Us” of Elizabeth Kolbert’s The Sixth Extinction: An Unnatural History, the author reveals the fact that the ocean is acidifying due to human activities, such as burning fossil fuels and deforestation. In this chapter, Kolbert notes that there was a lack of biodiversity near the vents at Castello Aragonese in order to present the oceans’ future possibility. One of the types of sea creatures that ocean acidification would devastate are the calcifiers, which are organisms that create shells or skeletons made of calcium carbonate (Kolbert 117-122). Credible sources of information, such as the EPA and the Smithsonian Institution, agree that ocean acidification poses a serious threat to marine calcifiers,
The coral reefs of the world are of vast importance because they host 25% of all marine life on the planet. Now that corals have been briefly described, we can see why the effects of climate change damage coral reef systems. Ocean acidification is a result of climate change. Acidification is caused by an increase in carbon dioxide in our oceans and leads to a decrease in the pH levels of seawater. This pH decrease reduces the ability of corals to make their hard skeletons.
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.
