Rising Acidity in the Oceans Causing Problems for the Oyster Population

Sorry, there are no airings at this time. Please check this page for future updates.

Rising acidity in oceans, due to an increased presence of CO2, is bad news for the oyster population. Madeleine Brand does her first field report for SoCal Connected on how industrial pollution is pushing the pH of the ocean to new never-before-seen levels, and in turn, causing marine animals' protective shells to become weaker and more susceptible to predators. Next a story on Southern California sea lion populations which have increased dramatically, becoming a nuisance because of their noise, smell and tendency to take over a location. Californians are having a difficult time finding a solution that works for both man and animal. And something new in billboards: artist Stephen Glassman has a plan to turn some of the signs into sustainable living bamboo gardens.
