Oceans Increase In Acidity

Increases in carbon dioxide (CO2) levels in the air have serious repercussions on the world’s oceans, which absorb roughly one third of the air-born carbon dioxide emissions resulting from human activities. When carbon dioxide dissolves in water, it forms carbonic acid, thus increasing the acidity level of the water. Furthermore, recent studies confirm that seawater is increasing in acidity at a rate much faster than what climate predictions had initially suggested.
This increase in the oceans acidity may have negative effects on marine life. Seashells, coral reefs, and large-shelled animals are in particular danger because they contain calcium carbonate, a substance that dissolves in acidic water. The rise in acidity may not be completely linked to increases in carbon dioxide in the air however. Researchers acknowledge that their findings may be somewhat influenced by nearby swells of deep ocean water loaded with carbon, indicating that their findings may not represent the oceans as a whole.

Questions:
1) Does this rise in the oceans acidity pose any dangers to human’s that have direct contact with it?
2) Considering that carbon dioxide can be absorbed by all water and not necessarily salt-water, can increases in carbon emissions have detrimental effects on fresh water organisms, and reserves for drinking water?

If this is not something caused naturally (or even if it is caused naturally) could there be a negative domino effect occurring — starting with ocean life. It will be interesting to see any effects caused in the coming years.

This is interesting and yet scary to see. I did a paper on the Great Barrier Reef in Austrailia and it is a shame to see marine life being destroyed by the amount of carbon dioxide. People need to eat and most fish for animals in waters. It will be difficult if they are living within these waters.

This is a very serious subject. The ocean is a major source of marine life on this planet and if these acidic levels continue to rise there could be major conquences for us. We need to reduce this as much as possible before we cause major destruction of the earth’s oceans.

The stduentds summary of this article was very alarming to me. I had no idea how high Carbon dioxide submissions release was. I also was surprised how acedic ocean water is. It is impoortant that students understand this because with high co2 levels marine life is efefcted thus hurting our planet and an area where a major source of food can be obtained (Ocean).

The ocean’s acidity could be very life threatening. However, it is possibly deadly to the species that live in it. Humans, or land dwelling creatures for that matter, will be affected indirectly from the loss of food source in the acidic water. It could also pollute the air with chemicals that would possibly affect anything above water. If the carbon dioxide were to absorb fresh water and not salt water, the fresh water organisms WOULD have detrimental effects. Therefore, whoever drinks that water will most likely suffer health problems.

I get angry when I hear about things like global warming and what it is doing to the world we live in. The thing is I feel that people are trying to do things like get safer cars for the climate and use better lightbolbs but that obviuosly isnt working because there is so much more going on that is overpowering that kind of stuff. The worlds governments need to take action if we are going to change anything. Regualations on cars, factories, and powerplants need to be closely looked at. We need to do something now or we wont be around in the next 30-40 years probobly.

After reading ths article summary I was taken back becuase I was so unaware about how high the carbon dioxide emissions were. It scary to think about what could happen to marine life if this gets worse. The ocean is very important to both humans and the marine life so it will be interesting to see what happens when time passes.

I agree that the water’s acidity is something that needs to be taken very seriously. This is putting our aquatic wildlife in danger. Eventually, these issues will reach our human population after tearing through the ocean life. This situation needs to become a priority.

The waters acidity can be very important and can be very minor. Right now, even though this article might make it seem like a big deal, i’m sure we can all still live if all the sea shells and coral in the ocean dissolved. The problem that will occur is if too much money is put into fixing it therefore causing economic problems elsewhere, or if this is a result of global warming is no where near the worst to come.

The effect that human beings have on the world around us is not something we can ignore any longer. If something drastic were to happen regarding the acidity level of the ocean, it would throw the entire system nature works in out of balance. I believe that we as a species can no longer be so selfish when it comes to protecting nature.

Every time I hear news like this i become more and more concerned about the state of our planet. People don’t take the effects of global warming seriously because they don’t believe they can reverse the trend, and they also haven’t seen any drastic side effects from global warming yet. However, if these trends continue we will continue to destroy our planet and all that lives on it. If the ocean’s acidity level is increasing even faster then scientists expect we could be seeing drastic environmental changes even sooner then many people think.
