In addition to the famous impacts of atmospheric carbon on global warming, there is an equally worrisome effect of carbon dioxide on the oceans: ocean acidification (or OA for short). Here at I2SEA we have a series of resources about OA, including Our Acidifying Ocean, which is an introductory activity and virtual lab (note: now mobile compatible!).
A student suggested that we start a conversation topic about OA, and here it is! Have you heard about Ocean Acidification? If so, are you worried about it? How do you think we can best raise awareness about it among your fellow students and the general public? Have you seen particularly good links or films about OA that you would like to share? What are you doing to address the problem?

Protecting the ocean is essential for life on Earth.Oceans are vital sources of oxygen,food and resources,and their conservation is crucial to our health and the health of global ecosystems.
Yes, I agree but how do we protect our ocean from acidification? First, we must understand what causes acidification. Ocean acidification is caused because more carbon dioxide is dissolving into the Ocean than ever before. It is natural for CO2 to dissolve into the ocean because the Ocean is a carbon sink. However, because of the industrial revolution and deforestation a surplus amount is being absorbed by the ocean which lowers the ocean's pH levels. The lower the pH levels are the more harmful it is to certain organisms who depend on the Ocean to survive. We must find ways to lower our carbon emissions as a whole to prevent any further extra acidification.

I agree, and even little things you can do at home can help protect ocean life. Things such as properly disposing of waste and conserving water are great ways to help even just a small amount. Another great way is to use less energy around the house, ways to do this are using energy efficient appliances and lightbulbs, keeping lights off when your not using them, and trying to limit large appliance usage. Even if these make a small difference if everyone pitches in we can help the bigger picture greatly. Many corporations also help contribute to restoring and conserving ocean life, they do this through many techniques such as rebuilding reefs and salt marshes that guard against storms and flooding, and protecting "Super Reefs" which are reefs which can survive hot temperatures and are used to help grow new generations of coral. We can make a difference by supporting and donating to these corporations which often rely on donations to operate.
I completely agree; oceans are one of the most important contributors to human life. However, humans have caused great damage to the ocean. So how can we protect the ocean, and keep it healthy? Well, according to National Geographic, there are over 5.25 trillion of plastic in the ocean. This plastic kills sea life and is incredibly damaging to the ocean. To fix this, we can try to limit the plastic we use and correctly sort our trash. For example, instead of buying Ziploc bags, you can buy glass containers, which are reusable and don't cause damage to the environment after you dispose of them. Limiting your use of plastic leads to less plastic being put in the ocean. Similarly, we can also protect our ocean from acidification. Ocean acidification is the decrease in the pH of the ocean caused by too much carbon dioxide. The ocean naturally absorbs CO2, but abounding too much can lead to acidificaction, which harms sea plants and animals. To stop this crisis, we can try to limit our carbon footprint. According to I2SEA, the average human produces 3 791 kgs of CO2 per year, and even more in the United States. To reduce this number, we can drive to avoid driving and can use public transportation, biking, or walking instead. We can also try to invest in renewable energy sources, like solar panels, which use energy from the sun for electricity. This not only reduces your carbon footprint but saves you money. You can also try to eat less meat. Animals produce a lot of greenhouse gases, and not eating meat means not giving money to these companies that exploit and harvest animals.
What is ocean acidification? Well, for starters, it is the ongoing decrease in the pH of the Earth's ocean. This is caused by the uptake of carbon dioxide in the atmosphere. This topic is important to the carbon footprint because it’s caused by all the carbon dioxide. When taking the survey, it gave us numbers that show how much carbon dioxide we produce throughout the things that we do. These things include any type of transportation, what kind of food you eat, how often you use energy in your house depending on if it’s gas or electric, and the things you buy. Bad things could happen to our waters if we don’t make an attempt to prevent ocean acidification. For example, the first thing that affects us is that we won’t be able to swim in the ocean. The second example is that these changes can affect seafood supplies and the ocean's ability to store pollutants, including future carbon emissions. You may ask, “what are some ways that we could prevent this though?” Well, even living in the midwest away from oceans, reducing the amount of carbon dioxide emissions at home, at the office, and on the road can still help with the problem. The carbon dioxide that we as humans release comes from burning fossil fuels. When we do that, it increases the acidity in the ocean allowing carbon dioxide to dissolve. The best things to do in a home that helps decrease the amount fossil fuels being burned include, swapping your furnace for a heat pump (many people in Canada rely on fossil fuels to heat homes), replacing your gas water heater with a heat pump water heater, trading your gas stove for an induction stove, and replacing your gas fireplace with an electric one. You can also use LED lights in the house that helps with the amount of energy being used. More things that people can do include turning off lights, computers, televisions, video games and other electrical equipment when you're not using them, limiting the use of air conditioning, and trying to use more things that take electricity instead of gas, like cars or stoves. These are all easy ways that humans can prevent ocean acidification. The hard thing is trying to get multiple people to go to beaches and pick up all the litter and trash people are throwing and letting dissolve into the ocean and atmosphere. For many years, people have been trying to get others to quit littering, lawmakers have even tried to make it illegal, but that doesn’t stop everyone. Although, the less people emitting fossil fuels, the better. Overall, if more people make an effort to do these things, then the ocean will be thriving again and coral reefs will stop fading in color.
Ocean acidification refers to the decrease in the pH level of the world's oceans, it is caused by the carbon dioxide from the atmmosphere. When Co2 dissolves in salt water, it forms carbonic acid, when then dissolve into bicarbonate ions and hydrogen ions, which lowers the pH of the water.
Why is ocean acidification a problem?
First, the lower of the pH level affects the lives of marine animals such as corals, mollusks, and some plankton species especially to build and maintain their shells and skeletons composition which is made out of calcium carbonate. If it is severe enough, it can cause problem in the marine food chain. Second, the coral reef decline. Coral reefs are vulnerable to ocean acidification. As they lose their ability to form and maintain their calcium carbonate structures, they will eventually collapses and die. This will affect the biodiversuty and the habitats supported by the coral reefs. Third, ocean acidification can distrupt the entire marine ecosystem, affecting species diversity and changing the predator prey relationship.
How do we solve ocean acidification?
One way that we can reduce ocean acidification whcih is to reduce the amount of carbon dioxide and other greenhouse gases which means to be conscious of your energy use. Some ways we can do this is to drive less, switch to fluorescent light bulbs, and compost your food waste. To protect the ocean, we must also stabalize the carbon dioxide in the atmosphere.
Ocean acidification is something that could ultimately affect us as well, since coral reefs are part of the ecosystem in the ocean. Each year, world trade in fish and fisheries products in 2023 is estimated at 65 million tonnes, which would also make our economy go down. To make the ocean acidification rate go down, we have to cut down our usage of fossil fuel and carbon emissions. To do this, we could take public transportations such as the metro or instead of driving, we could bike to the destination. That way, not only would you save the Earth, you would be exercising as well. The carbon dioxide in the atmosphere could be reduced by the way we live daily.
What is ocean acidification? It is when the Ph of the ocean is reduced over an extended period of time. Ocean acidification is mainly caused by uptake in carbon dioxide from the atmosphere. Carbon has been increasing over 200 years due to burning fossil fuels and land use change. The ocean absorbs a lot of carbon from the atmosphere, about 30%. When the carbon levels rise in the atmosphere they also rise in the ocean. When the carbon is absorbed by the seawater a chemical reaction happens causing more hydrogen ions. More hydrogen ions means the seawater will become more acidic but the water being more acidic carbonate ions to be less abundant. Certain fish have the ability to detect predators and when the water is acidic this ability decreases. Effects on other marine organisms are the extra acidity make it harder for things like coral and plankton to create their shell and skeleton. If the organism already has its shell it will begin to dissolve. Some things could benefit from the increased carbon. Some algae and seagrass are one of the ones that benefit from the carbon because it increases their photosynthetic and growth rates. More things the acidity can harm are mollusks, their shells could be very weak or dissolving. The marine organisms also can experience other changes such as abundance, changes in growth, development and survival because of ocean acidification. What can coastal decision makers do? Everyone can try to reduce their greenhouse gas admissions but the best way is to use the adaption approach. The adaption approach is changing things in your daily lives that will help produce less carbon into the atmosphere. What can we do to help? The only thing that will help the ocean acidification is lowering carbon admission. Ocean acidification is a serious thing that effects the environment, animals, etc and by reducing it the marine organisms will be able the develop normally.
Ocean acidification is a reduction of pH of the ocean over an extended period of time, caused by the increase of carbon dioxide in the atmosphere. Ocean acidification is not good because this can create conditions that eat away at the minerals used by oysters, clams, lobsters, shrimp, coral reefs, and other marine life to build their shells and skeletons. Not only is this bad for marine life but also human health. This condition can cause harmful algae species to produce more toxins and bloom later in acidified waters. This will only be harmful to humans if this is affected by shellfish or sicken fish consumed by humans. This is not only affecting humans but industries as well. For example, Alaska fisheries are suffering the consequences of ocean acidification. The Great Barrier Reef is being affected as well. There has been a decline of living corals, causing a reduction of habitat for living fish. Now how can we stop this? Helping stop emissions is a way we can help stop this since ocean acidification is caused by an increase of carbon dioxide. By trying to decrease the annual output, for example, cars, we can decrease the amount of carbon dioxide being released into the atmosphere, helping stop ocean acidification. Sure this might be a slow way of stopping ocean acidification but it will help over time. Along with decreasing the output of carbon dioxide we can also help by protecting and restoring marine and coastal ecosystems. Just planting kelp and seaweed forest allows them to absorb the greenhouse gasses and can help restore the oceans environment. In conclusion, if we want to keep out marine life and ecosystems safe we should take part in helping reduce/stop ocean acidification.

Ocean acidification is the reduction of the earth’s PH. This can create conditions that eat away at the minerals used by oysters, clams, lobsters, shrimp, coral reefs, and other marine life to build their shells and skeletons. This causes a human health concern. Although ocean acidification doesn’t make the water dangerous for swimming, it can upset the balance of the multitude of microscopic life found. This can affect the seafood supplies for us humans while also deteriorating the oceans ability to store pollutants like carbon emission. Ocean Acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and plankton when trying to form new shells and skeletons. The oceans have absorbed more than 150 billion metric tons of carbon dioxide emitted from human activities. Those activities include the burning of fossil fuels, agricultural activities, and deforestation. With the increase in those human activities, slow, long-term changes in the carbon cycle can influence ocean acidity over time. Today, more than a billion people worldwide rely on food from the oceans as their primary source of protein. About 20 percent of the world’s population derives at least one-fifth of its animal intake from fish. Since ocean acidification has a negative effect on marine species. This often alters the marine food chains and food supply to humans. As a way to help ocean acidification, humans can start by reducing carbon dioxide emissions at home, at the office, and on the road. Also another way that we can limit ocean acidification and help improve it is by acting on climate change and watching the amount of fossil fuels we use as a community. If we limit the amount of fossil fuels we use right now we can stop future harm to the oceans as well as future warming. Doing this we can significantly reduce the harm towards our marine ecosystem. Overall, Ocean acidification is something that might not be concerning to all but is definitely something that people to look at and try and solve. It won’t just take one person to try and solve the problem of ocean acidification but a whole community to try and solve an issue like this if we want a better future for our ocean.
To halt ocean acidification, we must reduce carbon emissions, promote renewable energy sources, preserve coastal ecosystems, and invest in research. Collective efforts are essential to safeguard the ocean's delicate balance and the biodiversity it sustains.
Yes, I agree that we must reduce carbon emissions to halt ocean acidification (as well as the other solutions you proposed). The ocean absorbs 30% of the carbon dioxide released in the atmosphere, and this CO2 causes the ocean's pH to drop. A lower pH means that the ocean becomes more acidic. This is a huge problem. As many of the ocean's fish depend on specific pH levels to detect predators, a more acidic ocean puts these organisms at risk--and perhaps the entire food web. This butterfly effect puts people at danger as well, especially coastal communities who depend on food from the ocean.

We have already polluted the ocean too much. We should protect and take care of our ocean. Human beings are spending trillions of dollars for military budgets and also a lot are used for a lot of things that are unnecessary, such as playing golf, drinking beer or burning a cigarette. If we spend more money towards saving the Earth and our precious ocean, we might have a chance of reviving our ocean into a cleaner place for the animals living in the environment.
I totally agree with you. U think very good keep thinking
I agree, people have been exploring the space but human have only explore 5 percent of our ocean and they should stop exploring outside the world and start exploring our own planet.
I also agree, there are too much trashes such as plastics, glasses, and other harmful material that human throw in to the ocean. We should keep researching about the ocean and also care for it to protect our environment.
I agree as well, there are many factors that are contributing to the negative impact on our planet. The ocean is one of the most important parts of the earth. The oceans hold a lot of life on earth, help regulate our climates, and are even very important carbon sinks. The pollution and poisoning of our waters do more than just kill the wildlife, when the trash and plastics decompose they use oxygen to do so, slowly taking away the oxygen that the ocean produces away from the atmosphere. On top of that it is a vital and important part of the water cycle.

I think would more people think like u the ocean were already a cleaner place of our Earth
I'm sure that a lot of our young generation would agree with you, but it's far easier said than done and many people in power right now are selfish, self-centered and don't really care about future generations and their quality of life.
I think your idea could work in a span of many years because it could be complicated to change the habits of humans that’s been going on for years and some parts of your idea has to do with the government. People would have to convince the government to not fund as much money into the military instead into our acidifying ocean. Some of the things you listed as unnecessary are drinking beer and burning a cigarette. These habits of humans may be a problem to just avert away from since the economy gets some benefits from it because of the money they produce. These companies producing beer and cigarettes also benefit people who are in need of jobs. These obstacles may cause problems to stop the use of money in unnecessary activities. We need to make a big organization or get a large following of people who want the ocean acidification to be taken seriously.
I agree, a lot of people are irresponsible with their money and spend it on meaningless objects to receive temporary pleasure. Some people even use it for drugs, smoking, and drinking (stuff that causes addiction in general) which is not only bad for the human, but for the environment as well. You can find so much cigarettes butts on the filthy roads which are just polluted with plastic and glass. If we all combined our money and put it to good use, like collecting plastic form the seas, we can all reduce our carbon footprint, save marine life, and cause less pollution.
I agree, we spend so much money on meaningless things, when we could be spending our money on trying to save our oceans. There is so much junk that gets tossed into our oceans and we should be trying to educate those who dont understand its importance. we need to be putting more money into saving our earth, rather then on things that are a one time use and meaningless.
Hey! You're so right! The biggest contributors to ocean pollution include runoff from human activities (both coastal and further inland) such as septic tanks, farms, and other big machinery. These examples are called nonpoint source pollution, coming from many different sources and much more frequent compared to its counterpart, point source pollution. Point source pollution is pollution with one origin, such as spills or discharge from oil rigs or other factories. When pollution like this happens, it messes with the quality of the water a lot (pH, acidity, temperature, etc.) and causes habitat loss for many sea animals that live somewhat close to land.
Ocean acidification is the reduction in the pH of the Earth’s ocean. This process takes place over periods lasting decades or more. Its main cause is the absorption of carbon dioxide (CO2) from the atmosphere. This, in turn, increases CO2 concentrations in the ocean. Between 23 and 30% of the CO2 that is in the atmosphere dissolves into oceans, rivers and lakes. Acidification is one of several effects of rising CO2 on the ocean. Other chemical changes to the ocean can also cause acidification. As the ocean absorbs CO2, seawater chemistry changes, which changes the living conditions of marine species. Many different species are affected, especially organisms that rely on calcium carbonate shells and skeletons, like mollusks, oysters and corals. Organisms like these struggle to build those parts of their anatomy when ocean waters have increased acidity.
Yes, this is very true and it's sad that it is happening. Although it is natural for the ocean to absorb the CO2 in the atmosphere, it does take a long time for the process to complete. With human activity increasing the CO2 emissions, it makes it hard for the ocean to keep up with all the carbon dioxide and balance it all out. And yes, marine life is getting heavily affected by the chemical change in the ocean, if the organisms you mentioned are affected then so will their predators and so on. Their habitats are also affected by ocean acidification, especially coral reefs. Many species have fled or many have died due to coral reefs being affected. With this, most regions have lost many species of fish and most of their food.
Ocean acidification is something that not that many people know about, but it is a very important thing. First of all, when the ocean is more acidic it weakens the shells of shellfish. Like crabs, clams, mussels, and shrimp. The importance of this is that it makes them vulnerable to predators which will stop them from making it too adulthood. Which could lead to extinction. Another important animal that is at risk is corals. Ocean acidity is causing them to get thinner and thinner each day which will eventually make them extinct as well. Lots of coral reefs are dying out rapidly right now imagine how many will be alive by 2050. Scary right.
Yes, the increase in carbon dioxide in the atmosphere has caused the ocean to absorb more carbon dioxide. Carbon dioxide and water produce carbonic acid, which releases hydrogen ions. The increase in hydrogen ions decreases the ocean's pH. Our ocean has an average pH of 8.1, but some experts say that the pH could drop down to 7.8 in the 21st century. A large cause of this increase of carbon dioxide is from the burning of fossil fuels and deforestation. I agree that ocean acidification will be detrimental to many organisms and if we don't do anything about it, could cause the extinction of these animals. The low pH also degrades the coral reefs, which serve as a home to many organisms. Coral reefs also protect coastal lands from erosion, so it will directly affect communities. The best solution to ocean acidification would be to stop burning fossil fuels! We need to stop producing so much carbon dioxide.

The coral reefs are disappearing quickly. Coral reefs make up of most of the fish in the oceans habitats. Coral bleaching is destroying the Great Barrier Reef and other small reefs all over the world. The ocean is loosing it’s biodiversity allow with the fish we humans depend on
I agree, protecting coral reefs is substantial to the environment of ocean life as well as the food chain, not only is the major for ocean life but also humans jobs resources because with out collar reefs there wont be huge attractions for sourest. There will also be less fish for fishing.
I agree, this topic is not discussed as much but I think is equally important. This is extremely important to ocean life and we need to do something to help preserve coral reefs.
I agree if all the coral reefs die there will be nothing to slow down the force of waves and that will cause tsunamis. Not wearing sunscreen in to the ocean will help a lot because the sunscreen kills the corals. If the reefs die, a lot of fishes will lose protection and the food chain will be messed up. Protecting the reefs is very important because it will effect everything from land to sea.

Ocean acidification is an important environmental issue caused by increased carbon dioxide absorption in oceans. It’s something we all should worry about because it threatens marine ecosystems, particularly coral reefs and shellfish. We need to raise awareness about OA and take action. The documentary “Chasing Coral" might help you understand OA better the effects it has on marine life. We have to reduce carbon emissions and promote sustainability to protect our oceans.
I agree greatly, the ocean over the years has taken in a lot of CO2 which has made things such as wild life and reefs become less dense and started to kill them. I think this is a great idea on showing how to help this and is a very important topic. It is much more then just doing the little things everyone on this earth needs to contribute to help our ouceans.
Agreed living on the coast the effects of the ocean are very important to me. The oceans acidifying is killing off corral and many fish that rely on the reefs. Among killing plants on the ocean floor that kill the bottom feeder sea animals causing the fish population do decrease.
Ocean acidification, caused by rising CO2 levels, endangers marine life and ecosystems. It harms coral reefs, shellfish, and biodiversity, disrupting fisheries and tourism. This issue also impacts climate change, as less CO2 can be absorbed by the ocean. Solutions include reducing CO2 emissions, creating marine protected areas, and raising public awareness about the problem. Addressing ocean acidification is crucial for protecting our oceans and the diverse ecosystems they sustain.
I agree with you rising CO2 levels cause ocean acidification. When there is too much carbon dioxide in the atmosphere, some of it will be taken in by the ocean. This is a problem because the rise of CO2 is lowering the pH level in the ocean. Animals like oysters, scallops, and shellfish need shells to survive in the ocean but cannot form them because ocean acidification breaks down their shells.
I agree that ocean acidification is caused by CO2 because in the past during the great dying. Tons of CO2 we put out in our atmosphere the ocean took in some of the CO2 and this caused the ocean to become very acidic. Just like in the past we are getting more CO2 in our atmosphere. Our ocean is also becoming more acidic, if it’s anything like the past then most likely the ocean is becoming more acidic because of all of the CO2 in the atmosphere. The ocean becoming more and more acidic is very crucial because the acidity in the ocean can break down shellfish and crustations shells, taking away their protection. Eventually the ocean can become so acidic that it won’t be habitable.
Ocean acidification is the lowering of the ocean's pH levels. It is caused by carbon dioxide gas in the atmosphere dissolving into the ocean. The ocean is becoming acidic because of these lowering pH levels which are leading to the death of coral and other aquatic organisms. This is bad because it will not only affect the oceans, but animals on land will be affected too. A large majority of humans find their main source of protein from sea animals, and many humans will be malnourished without healthy fish and other sea food. We need to stop ignoring problems like ocean acidification just because it isn't affecting you, because it is probably affecting billions of others.
I feel like algae aren't talked about as much as they should be. They make up roughly 70% of the oxygen in our atmosphere and many marine creatures eat them, they are essential to our survival. Now, algae is battling ocean acidification and balancing out the CO2 in the water. I know algae are capable of handling a lot of CO2 since it's their food, but I feel the need to bring attention to the fact that if there's too much CO2 in the water for algae to balance out, the change in pH from ocean acidification can possibly reduce algal abundance. Do you guys think that algae and its importance should be talked more about, not just because they produce over half of our oxygen but also because they are balancing out ocean acidification? Also, if pollution increases, overgrowth of algae may harm the ecosystem itself. I feel like this needs to be talked about more.

I think we need to raise awareness for this problem because I've never thought about the algae and I know many others haven't either
Ocean acidification is an increasingly worrying topic. Coral bleaching in particular is concerning, 1 in 4 ocean species rely on coral reefs for habitat. Losing a quarter of the oceans biodiversity would have drastic effects for the remainder of the species in the ocean as well as for humans. Many humans rely on the oceans for food, or they are an integral part of peoples' culture. That brings me to my second point, 1 in 7 people in the world would become extremely malnourished because their main source of protein is sea food. If humans allow ocean acidification to continue the effects will be fatal.
The ocean needs saving. Seafood is 1 in 7 peoples main source of food. If the seas and sealife gets destroyed, around 1 billion people around the world will lose there main source of food. If we keep polluting the seas we will lose thriving coral reef habitats which gives shelter for 1 in 4 ocean species. We can lower ocean polluting and acidification by lowering carbon emissions. If we lower barbon emissions that enter the sea, the reefs can be healthy and stable again. we can do this by cleanjing up beaches that are littered, we can stay away from plastic and only use it if needed. If we do those 2 things reguarly, we can keep the oceans clean for generations to come.
Ocean acidification is a serious issue. Coral reefs, where many ocean animals live, are at risk. If we lose these animals, it's bad for all sea life, including us. Lots of people get their food from the oceans, and for many, seafood is their main source of protein. If we don't fix ocean acidification, it's a big problem for sea life and our food. We must work together to protect our oceans.
I agree, I think that climate change has a big impact on our ocean and the rising sea levels. As when the amount of CO2 in our atmosphere rises, our temperature increases which makes the earth warmer and causes icebergs to melt resulting in sea levels rising. When our sea level rises more land goes into water. Some ways we can reduce CO2 is switching from gas cars to electric cars since gas cars give out CO2.
Ice is increasing the sea level at an alarming rate. Both the International Panel on Climate Change (IPCC) and the US National Climate Assessment say that ice loss was the largest contributor to sea-level rise during the past few decades. They also say that it will continue to be the largest for the next century. The biggest way ice melts is through sea ice, when the ice gets warm it melts and that raises the sea levels. Another way ice melts is through land ice, land ice melts on land and the water travels to the oceans or streams.
El deshielo y el aumento del nivel del mar son sin duda preocupantes y tienen múltiples efectos en nuestros ecosistemas. Uno de los aspectos impactantes es cómo estos fenómenos pueden influir en los sistemas fluviales alrededor del mundo. Por ejemplo, aunque no es un resultado directo del deshielo, es interesante considerar cómo algunos ríos han sido históricamente alimentados y afectados por los glaciares y otras fuentes de agua dulce. Tomando como referencia el Río Amazonas o el Río Nilo, ambos forman parte de los ríos más largos del mundo y han sido vitales para las comunidades a lo largo de la historia. Si te interesa saber más sobre estos impresionantes sistemas fluviales, este artículo ofrece una visión detallada sobre los ríos más largos del planeta y su significado geográfico y cultural.
I agree with what you said, but I would like to add on an emphasis on why ice is rapidly melting at such an alarming rate in the first place. As I'm sure you all know, climate change is the result of increased amounts of greenhouse gases in the atmosphere, which reabsorb the sun's heat when it tries to leave Earth. You may also have known that over the last few decades, specifically the industrial revolution and beyond, greenhouse gases such as carbon dioxide has been released into the atmosphere at faster rate than ever. But what you may not have known is but according to Columbia Climate School, only 0.04% of our atmosphere is made up of Carbon Dioxide. Even this small percentage is enough to drastic changes in our temperature and weather patterns, one of which you mentioned, is the melting of ice, and this includes places like Antarctica. As much as increased sea levels is a problem from people and things that live near shores, there are unfortunately, there are other, stronger ways climate change harms our Earth. Not only is sea level rising, but ocean acification, which is the change in pH of sea water, which harms and kills ecosystems. This is resulting in less food and loss of species. I believe that climate change affects everyone's daily lives and their lifestyles, and that the effects of climate change are not all talked about enough.
Ocean acidification, caused by rising CO2 levels, endangers marine life and ecosystems. It harms coral reefs, shellfish, and biodiversity, disrupting fisheries and tourism. This issue also impacts climate change, as less CO2 can be absorbed by the ocean. Solutions include reducing CO2 emissions, creating marine protected areas, and raising public awareness about the problem. Addressing ocean acidification is crucial for protecting our oceans and the diverse ecosystems they sustain.
Ocean acidification refers to a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere. It is directly connected to our carbon footprints and the increase of the greenhouse effect. Ocean acidification is affecting the entire world’s oceans, including coastal estuaries and waterways. Many economies are dependent on fish and shellfish and people worldwide rely on food from the ocean as their primary source of protein. The ocean provides us with invaluable benefits and services such as Renewable Energy and Food; More than 3.5 billion people depend on the ocean for their primary source of food. Fish supply the greatest percentage of the world’s protein consumed by humans. The most effective way to limit ocean acidification is to act on climate change, implementing solutions to dramatically reduce the use of fossil fuels. This includes working on lowering our personal carbon footprints and being more environmentally aware.
as the ocean becomes more acidic we are going to lose the shelled creatures. their shells will dicinigrate and they will parish while we keep driving our cars and burning more carbon. but losing these animals will effect us as food chains fall apart and more sea life goes underfed. 1 in 7 people survive of fish, and if fish become small and underfed, much of our population will too. not only that but many people will lose their jobs. the fish indestry is large and important. i think the first people that will see the first major impacts of climate change will be the fish farmers that work with the ocean.
I agree, ocean acidification has been the cause to mass extinctions in the past and this could very well happen again. Lots of the worlds population rely on fish. The death of our oceans is one of the largest challenges of our generation. People in the fishing industry already are seeing decline in sea life’s health and quantity. For example, in Maine the lobster industry has been suffering greatly because of rising ocean temperatures. If temperature increase continues, 5600 people could lose their jobs.
I completely agree, as the ocean becomes more acidic it is bound to affect our marine life. And with people being dependent on the amount of marine life just to have a full stomach it can cause many problems for us in the future going forwards. Also I agree with fish farmers being the first affected, as with any other job associated with marine life if the marine life continues to deteriorate it will result in many people to be strpped away from their livlihoods. Yet this is also why this problem must be realized by people around the world, that this is a major consequence coming from climate change.
The moment the industrial revolution started and our human population began to skyrocket the total amount of CO2 being launch into the atmosphere has increased but also the excessive CO2 have been being absorbed by the our ocean as well. This absorption has caused the pH levels of our ocean to decrease with a 30% more acidity. With this acidity it has affected marine life and marine ecosystems throughout the ocean. Because ocean Acidification is just one of the effects of climate change the solution remains that same we must find ways to reduce carbon emissions. With solutions such as cutting off our use of fossil fuels and replacing our energy with more natural power sources. Another way to solve this problem is to cultivate and allow more coral reefs, sea grass, seaweed, or any other marine plant that can absorb the CO2 to counteract this increased amount being emitted.
Ever since we began burning fossil fuels for energy, 30% of the carbon dioxide has been absorbed by our oceans. When our seawater absorbs the carbon dioxide it increases the acidity of the ocean. This is very harmful to the sea life, as many fish and marine mammals are very sensitive to changes in pH. Among these are our coral reefs, which already struggle from bleaching caused by temperature change. Because of the dependence of coastal communities on the ocean, if our sea life dies off or becomes endangered, many economies will be at risk. https://oceanservice.noaa.gov/facts/aci … o%20a,CO2)
Ocean acidification happens when there is an increased amount of carbon dioxide in the atmosphere. When this happens, it causes the PH levels of the ocean to drop, meaning that it causes the ocean to be more acidic. What’s more is that ocean acidification causes carbonate ions to decrease, which are used to build shells for many sea creatures. Consequently, this can lead to many organisms to be at risk, and ultimately the food web as a whole. Because of this, all marine life are at risk of extinction if global warming continues. This has great significance because many places rely on the ocean for food. Ocean acidification does not only affect marine life, but us humans as well.
Ocean Acidification harms marine life including reefs and shellfish. As the ocean absorbs more carbon dioxide, it becomes more acidic, making it difficult for organisms to build and maintain their shells or skeletons. This disrupts the marine food chain and can lead to cascading effects on the entire ecosystem. It's important to address ocean acidification to protect the health of our oceans and those that depend on them. We can do so by reducing the fossil fuels that goes into the ocean, using cleaner sources of energy, and protecting/restoring coastal ecosystems such as mangroves and sea grasses to help absorb carbon dioxide.
