Giant toxic waste dump site discovered in the Pacific Ocean
A massive underwater toxic waste site has long been suspected off the Southern California shore, since industrial companies used the ocean as a dumping ground until 1972. Now marine scientists have identified over 25,000 barrels they believe contain the toxic chemical "DDT" in the Pacific Ocean. Stephanie Sy talks to David Valentine, a UC Santa Barbara professor of microbiology, about the barrels.
