Warming and acidification from carbon dioxide in our atmosphere are having long-term effects on life in our oceans. In this video from
Earth Vision Trust, marine ecologist and geologist Joanie Kleypas, of the National Center for Atmospheric Research, explains how carbon dioxide changes the pH level of the ocean and how that leads to coral die-off. She also helps us understand how humans can help restore damaged coral reefs.
