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 is not always something we hear about when talking about climate change. I had never though much about it until my class talked about it. It turns out that this issue is extremely important, considering it effects nearly all ocean life. When CO2 enters the ocean it creates carbonic acid, which makes the oceans ph levels decrease. When the oceans ph levels decrease, the shells of marine organisms start to dissolve, giving them almost no protection against predators. Ocean acidification effects marine food webs as well as humans, so we should do everything possible to stop it. The main way you can help is to reduce your carbon footprint. Eating less animal products, taking sustainable forms of transportation, and conserving energy are all great options.
