Ocean Acidification: Downfall Of The Marine Ecosystem

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.

The ocean is a very delicate ecosystem in which the slightest change of pH or chemical composition will result in devastating results. Between 25 and 40% of anthropogenic carbon emissions have entered the marine area since the industrial age (Sabine et

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.

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

The authors of the article starts by explaining ocean acidification, the aftermath of excessive carbon dioxide reacting with seawater resulting in carbonic acid, could negatively affect one of the core strategies of survival: sex (p.68). As the ocean decreases in pH level, marine life is impeded and interfered. Shells and skeletons of clams and mussels become harder to develop and the health of countless organisms are threatened. Although the oceans absorb one-third of all CO2 produced by humans thus reducing global warming, it is at the expense of organisms in the sea (p.69).

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.

The ocean has became nearly 150% more acidic. Which the ocean has experienced in nearly 20 million years.

The first organisms that ocean acidification affects are calcifying creatures. These include creatures like oysters, calcareous plankton, clams, sea urchins, and coral. The ocean normally has enough carbonate ions dissolved for calcifying creatures to use to create their shells. Ocean acidification negatively affects the ability for these organisms to build their shells. As carbon dioxide dissolves into the ocean it reacts with the water to form carbonic acid (What is Ocean, 2015). Also, as more carbon dioxide dissolves into the ocean, it reacts with seawater to make H+ ions. These H+ ions compete with calcifying creatures for the carbonate ions. The H+ ions often win making it much more difficult for these shelled creatures to make their shells (Cripps et al., 2014). Creatures like conch shells, oysters, and clams are the most negatively affected. But not all creatures are immediately affected. Some organisms such as crabs and lobsters and crabs actually grow heavier shells to combat the effects of changing pH. This adaptation

This threatens coral ecosystems, mussels, clams, and dozens of other species just on the ocean acidification side by weakening their protective barriers and altering the pH of the water. Polar bears, sea turtles, right whales, African elephants, and frogs are just some of the few animals being driven to extinction right now because of climate change. Obviously, these species are not dying off for no reason: the big bad guy is the results of rising levels of c02 due to human’s mass consumption of it for transportation, electricity, and industry. And scientists agree – “99 percent of currently threatened species are at risk from human activities,” says the Center for Biological Diversity, adding that global warming is one of the three main abusers. Ocean acidification is global warming’s “equally evil twin”, as Elizabeth Kolbert writes in her novel The Sixth Extinction. Clearly, human’s c02 waste is causing environmental issues that threaten and eventually extinguish plant and animal

Sometimes called “climate change’s equivalently destructive twin”, ocean acidification is becoming more and more noticeable as the seawater’s changing chemistry begins to cause environmental and economical problems. When the Industrial Revolution began around 1760, fossil fuel–powered machines gained an immense amount of accessibility and popularity. Since then, carbon dioxide (CO2) levels in the atmosphere have risen enough to change the pH of the world’s oceans. Given that the ocean absorbs almost half of the CO2 that is released into our atmosphere, ocean acidification is inclining into an even greater problem as fossil fuels become a more common energy source in our society. Higher acid levels can harm wildlife, disrupt the food chain, and negatively impact industries that rely on the ocean for business. Ocean acidification is causing growing dilemmas for both marine ecosystems and ocean-based economies. Although many companies and organizations are attempting to fix this problem, acidification is still threatening to cause increasingly harmful issues for the future.

Ocean acidification isn’t hard to understand because the name is self-explanatory but in simpler terms, carbon dioxide is pushed into the water become more acidic. Ocean acidification has much effect on how the flora and fauna of the sea adapt and live. The “subtle change in chemistry lowers the water’s saturation in aragonite” that Slezak (1) explains can be very effective how coral grow and build. Currently, oceans are staying at a rate of 3.8 aragonite saturation which isn’t entirely horrible but slezak (1) mentions many scientists believe “corals will stop building reefs when the saturation state drops below 2.5”. However, coral will just begin to ache once it hits the 2.5 point, but it’s “not a point of no return beyond to which they

ocean’s eco-system that we wouldn’t be forced to adjust to prosper in a safe and effective way of survival. An organization once stated that, “the air that you breathe, the water you drink, the food you eat, the products that keep you warm, safe, informed, and entertained — all can come from or be transported by the ocean, you hurt it is, its just going to hurt you back,” (Protect Plant Ocean). That quote relates back to this, ocean acidification is a socio- ecological system that will have to carry out the repercussions of being universal, evidently supported and complex. It is a wicked problem that will be hard to turn around and what our society is doing is we are learning how to deal with the effects by having the ability to survive without

Ocean acidification has recently become a big problem. Coral reefs and fish are dying, causing local economies to lose up to $375 billion every year from lack of tourism and fishing profits (Worland). Ocean acidification is caused mainly by carbon dioxide being pumped into the atmosphere by burning fossil fuels. The carbon dioxide “reacts with water molecules to form carbonic acid,” thus increasing the acidity (Stone). “The ocean currently absorbs about a third of human-created CO2 emissions, roughly 22 million tons a day,” according to National Geographic. We’ve already “disposed” of 530 tons billion tons of carbon dioxide into the ocean. Because of this scientists are now studying the ocean and have thought of two possible ways to reduce acidity - geoengineering and cutting carbon emissions.

The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of
