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?

Ocean Acidification
I have personally never heard of ocean acidification. I am not that worried because I have never heard of it but I do know how polluted our rivers and lakes are. The best way to bring awareness about it is to just educate them. I don't have any good links about it to share.
If you don’t know a problem, that’s doesn’t mean that this problem doesn’t exists!
Instead «important people» don’t say the problems if they can earn something from these problems!
I agree with your opinion on the rivers but ocean acidification is a very serious and important problem as well. It's alright if you don't know, but it is important to learn about problems like this. Ocean acidification is when the pH level in the ocean decreases because of a large amount of extra CO2. That makes the ocean more acidic after carbonate ions get defeated by hydrogen ions. Less carbonate ions mean organisms with shells are unable to build their shells, but without shells the organisms would die.
It would be great if you could join and educate others about the rivers, lakes and ocean. 
Though ocean acidification may not be currently impacting many lives directly, its impact on marine life can cause several issues for humans in the future! When there's increased carbon dioxide in the environment from the burning of fossil fuels, the pH of the ocean decreases. Thus, carbonate ions in the water are less available, and organisms that have shells and skeletons can't fully develop. As these organisms decrease, the ecosystems will be unbalanced. In addition, coral reefs that are great habitats for organisms will decline as well. Seafood consumption for humans would be scarce, and many of the marine organisms will become extinct.
Here's a great website!
