Ocean surface waters are now 30 percent more acidic than they were 200 years ago, largely the result of people burning fossil fuels. The change in ocean chemistry makes it difficult for many animals to grow shells or skeletons. Special correspondent Scott Shafer of KQED in San Francisco reports on how acidification is affecting ocean life like abalone and oysters in the Bay Area.

Ocean accidification is interesting phenomenon; so many people rely on the oceans as a source of delicious food, to think that those ecosystems could collapse is a sobering thought.
