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
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.
