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?

Carbon in the Oceans
Our oceans are being polluted with harmful plastic and other toxins as well as absorbing more carbon because of how much is in the atmosphere. The ocean normally absorbs carbon from the atmosphere but with such high levels right now on earth, the ocean is absorbing more than it should be. The ocean is now absorbing 22 million tons of carbon each day which has resulted in the ocean becoming 30 percent more acidic than it was in the 18th century. This is lessening the pH number in the ocean and affecting life within it. Coral reefs are being damaged and killed which is dangerous as they are a home for 4,000 species. Reducing energy is one way to help prevent further damage. Using public transportation a few times a week too can also limit the carbon emissions which will help.
