The Negative Effects Of Ocean Acidification

The rising carbon dioxide (CO2) from the burning of fossil fuels and other human activities continues to affect our atmosphere, resulting in global warming and climate change. This carbon dioxide is also altering the chemistry of the oceans, causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have drastic consequences on marine ecosystems. Such as altering species composition, disrupting marine food webs and ecosystems and harming fishing, tourism and other human activities connected to the sea.

Ocean Acidification is a process that occurs everyday and majorly affects our planet, but most people don’t even realize it exists. Though it can technically be argued that Ocean Acidification has some benefits for the planet, most of the time the effects of this process are very poor and negatively affect the entire world around us. Human evolution has played a major role in contributing to Ocean Acidification. Whenever humans use energy we release Carbon Dioxide into the atmosphere or also known as CO2. This can be in the form of burning fossil fuels from the ground or the removal of national forest by burning. CO2 is a greenhouse gas, which means whenever we can emit it in large quantities or unnatural amounts it can have negative effects on the atmosphere. These high levels of CO2 in the atmosphere result in climate change and more specifically Ocean Acidification. Ocean Acidification occurs when excess Carbon Dioxide is absorbed into the ocean. When this process takes place it can completely disturb the chemical balances of the water. For example, it can reduce pH levels, Biodiversity, and the abundance of calcifying species.

This increase in oceanic inorganic carbon has offset the seawater carbonate chemistry by causing increasing concentrations of CO2 and bicarbonate, while causing decreasing concentrations of carbonate and pH levels (Dedmer 2013). Rost and colleagues (2008) express that emissions of fossil fuel have caused an immense increase in the levels of atmospheric CO2, which are then deposited into the surface water of oceans. This increase in carbonic acid is in turn decreasing the pH balance, which poses a threat to marine organisms.

Since the beginning of the industrial revolution, mankind has slowly increased the total greenhouse gas emissions that enter the atmosphere. Over time, this pollution began to add up. Now planet Earth is struggling to maintain its health with the combined forces of global warming and ocean acidification looking to bring demise. From all portions of the world, troubling changes are emerging in the chemistry of our oceans’ waters. The oceans takes in around a quarter of the Carbon Dioxide that mankind releases into the atmosphere every year, so as atmospheric Carbon Dioxide levels rise, so do the

Ocean acidification is becoming on of the most concerning subjects compared to global climate change. pH is the level of acidity, seven being neutral fourteen being most basic and zero being most acidic. The pH levels in the ocean are dropping and becoming more acidic. This is happening because of increasing carbon dioxide emissions. The ocean is taking in the carbon dioxide from the atmosphere.

About half of that man-made CO2 has been absorbed by the oceans, increasing the concentration of carbonic acid, which has caused the oceans to become more acidic. Over the past 300 million years, ocean pH has averaged about 8.2. Today, it is around 8.1, a 25% increase in acidity over the past two centuries. That increase is projected to reach 150% by the end of this century, a rate of change not seen in 65 million years. A more acidic ocean inhibits shell growth in marine animals such as corals, crustaceans and mollusks, and disrupts entire food chains all the

Ocean acidification is where the ocean water becomes more acidic due to the amount of carbon dioxide in the water. Humans use fossil fuels such as coal, oil, and natural gas that release large amounts of carbon dioxide into the atmosphere. Oceans absorb about one quarter of the carbon dioxide released each year, and since the amount of carbon dioxide in the water increases, it becomes more acidic (Ocean Acidification, NOAA). More acid in the water means that it will be lower on the pH scale and will release more hydrogen ions. This is in comparison to having more base in the water, where it will be higher on the pH scale and will release more hydroxyl ions. The pH scale rates the concentration of hydrogen in water, and acidic water releases more hydrogen ions than basic water. The scale goes from zero to fourteen, where a pH of seven is neutral, a pH less than seven is acidic, and a pH greater than seven is basic. Oceans have an average pH of 8.16, but that number is predicted to decrease

This tragedy is called ocean acidification. Ocean Acidification is the rapid decrease in the pH, (pH is the measure of ocean acidity,) of the Earth's ocean, caused by its intake of carbon dioxide from the atmosphere. This rapid increase of carbon dioxide is directly coming from the large consumption of fossil fuel that humans constantly release into the air for our own selfish reasons. As we increase the level of carbon dioxide that is being released in a short amount of time, we are letting small amounts seeps into the earth's oceans through the continual water cycle. When the carbon dioxide seeps into the oceans, it begins to turn into carbonic acid. In small amounts, carbonic acid is not seriously harmful and is usually part of the ocean

“How acidification threatens ocean from the inside out: Carbon dioxide emissions are making the oceans more acidic, imperiling the growth and reproduction of species from plankton to squid”, by Marah J. Hardt and Carl Safina addresses the dangers of increasing acidity in the ocean caused by carbon dioxide. Hardt, a research scientist and writer, is the founder of Ocean Ink. Safina, an adjunct professor at Stony Brook University, is the founding president of the Blue Ocean Institute.

Over the past couple of years, no other issue has received more attention in the marine community than ocean acidification. Marine biologists have been constantly working towards solving this issue and are hoping to see improvement’s very soon. Ocean acidification refers to the relentless growth in acidity of the Earth’s oceans. This on-going acidity has attributed to an important element; a constant rise of carbon dioxide levels in the Earth. The number one reason this issue is still happening is because of burning fossil fuels. In addition to burning fossil fuels, it has come to a point where it has enlarged a large amount of carbon dioxide by releasing it into the atmosphere. Chemists have taken this issue into attention that carbon enters the ocean and combines with seawater to fallout acid, which boosts the level of acidity. This process is known as ocean acidification.

Ocean Acidification is affecting our life more than we ever thought it would be able to. When people first think about oceans, they don’t see the diversity of life that is in there or how much we depend on those organisms and the ocean itself. We only see this ginormous body of water, where some feel like it’s not a big deal if anything happens to it. Ocean acidification (as defined by NOAA) is “ongoing decrease in the pH of the Earth’s oceans, cause by the uptake of carbon dioxide from the atmosphere, this then creates an acid”. Each year the ocean absorbs at least 25-30% of all CO2 from human activity. This can be a huge threat to the diversity of the ocean and the benefits it provides to society. The rate continues to go up, more so than anyone would have thought it would and as these continue to raise the risks we are facing could be bigger than we thought and we could soon be facing a mass extinction.

Ocean acidification is the process in which the ocean soaks up carbon dioxide and its pH lowers. At the current point in time, the pH in the ocean has dropped 0.1 pH. ALthough this doesn’t seem like much, since pH is logarithmic, this means that the ocean is 30% more acidic than before. This jump in acidity will literally melt the shells of oysters, and sometimes even fish. What causes ocean acidification is carbon dioxide. Normally, carbon dioxide wouldn’t be that much of a problem as the ocean has a natural buffering system. The carbon dioxide would combine with the water molecules and create a bicarbonate ion then it would gain another H+ molecule and would create a carbonic acid. This acid replaces the much needed carbonate molecules which

Ocean acidification can be defined as the continuous decrease of the pH of Earth’s oceans. This process occurs as a result of the rise in carbon dioxide emissions in the atmosphere. Due to the rapid industrialization of various countries on Earth, humans have become more accessible to energy by utilizing non-renewable resources that are derived from carbon in the ground.

Ocean acidification is caused when the CO₂ from the air enters into the ocean and bonds with sea water creating a toxic acid called carbonic acid. Carbonic acid reduces the natural pH levels of the water which as a result has been increasing the ocean acidity by 30%. This reduces the calcium concentration in the water, making it hard for crustaceans like crabs and prawns to build their shell. This means that they are more vulnerable to predators, and we can all figure out what happens when an entire species is vulnerable to predators. Air pollution is not the only factor that causes the water to become polluted. In fact, there are many more including fertilizer that gets washed into the oceans and also oils spills. According to the Water Project, 783 million people worldwide do not have access to clean and safe water, and according to the Worldwatch Institute, approximately 450 million kilograms of pesticides U.S. farmers use every year have now contaminated almost all of the United States' streams and rivers, and the fish living in them.

Carbon dioxide is a greenhouse gas that we exhale in our daily lives. Plants use carbon dioxide to create oxygen that all mammals use. However, carbon dioxide can also change the chemistry of the ocean, this is often referred to as ocean acidification. The excess carbon dissolves into oxygen in the water, producing a chemical called carbonic acid. This acid causes the ocean to become more acidic. In the eighteenth century, the pH was 8.07 which was slightly basic. Currently, the pH is around 8.01 this is about a twenty-five percent increase in acidity. (National geographic) While this slight change may not seem outrageous, it is causing multiple marine life struggles. The acid melts the shells of pteropods causing a low supply of food that would support larger fish.
