That carbon dioxide causes a rise in acidity that threatens biodiversity in ocean environments such as coral reefs.

Here & Now's Meghna Chakrabarti speaks with Laetitia Plaisance, who appears in the NOVA special "Lethal Seas." She's a marine biologist and research scientist at the Smithsonian's National Museum of Natural History who has studied coral reefs under both normal and acidic conditions.

"Lethal Seas" is scheduled to air tonight on PBS stations around the country. Check local listings here.
