This groundbreaking NRDC documentary explores the startling phenomenon of ocean acidification, which may soon challenge marine life on a scale not seen for tens of millions of years. The film, featuring Sigourney Weaver, originally aired on Discovery Planet Green.
The powerful before-and-after photographs below were shared as evidence of ocean acidification at the 2012 International Coral Reef Symposium in Australia. Please help spread awareness about ocean acidification by pinning these before-and-after photos and starting the conversation about ocean conservation. #OceanAcidification
