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 a grave environmental issue caused by the absorption of excess carbon dioxide (CO2) by the world's oceans, resulting in a decrease in the pH levels of seawater. This phenomenon has far-reaching consequences for marine ecosystems, as outlined in a study published in the journal "Nature" in 2015. The research indicates that rising acidity disrupts the growth and reproduction of many marine species, particularly those with calcium carbonate shells or skeletons, such as corals, mollusks, and some plankton species. As the oceans become more acidic, it becomes increasingly challenging for these organisms to maintain their vital structures, threatening the entire marine food web. Ocean acidification also has broader implications for global fisheries and economies, as it poses risks to the livelihoods of millions who rely on the oceans for sustenance and income. Tackling this issue is essential not only for the preservation of marine biodiversity but also for the well-being of societies dependent on healthy oceans.
