Cheryl A. Logan discusses the causes, effects, possible solution, and awareness of ocean acidification. Ocean acidification is caused by carbon dioxide dissolving into the Earth’s oceans, generating carbonic acid. Over the past 200 years the pH of the ocean has decreased by 0.1 units, a 30% drop. Ocean acidification affects the ability of several species to calcify, which could affect the food chain and indirectly damage the economy. Scientist have looked into geoengineering as a way to palliate the situation, but reducing carbon emissions is the largest way to help.
Logan also looked into the public and government awareness of ocean acidification. While it seems that the public knows little on the subject, no actual research has been done to prove this. However, the government seems to be much more informed and there are several organizations that are working to improve the situation. In general, Logan suggests using social-networking sites, films, the blogoshpere, and other media to increase awareness.
