Ocean and Coastal Acidification

Ocean and Coastal Acidification

The carbon dioxide that humans release to the atmosphere by burning fossil fuels is increasing the acidity of the ocean. This phenomenon, called ocean acidification, impacts marine life and the people who depend on them. In addition, land-based sources of pollution can contribute to localized acidification of coastal waters. Learn more about Ocean and Coastal Acidification.
