Scientists say fresh water under the ocean could help alleviate water scarcity

An international team of scientists is exploring a vast source of drinking water deep under the sea floor off the coast of Massachusetts. As water scarcity increases, the team believes undersea aquifers could be a helpful source. The World's Host Carolyn Beeler spoke to Brandon Dugan, a chief scientist on the expedition. He's a geophysicist at the Colorado School of Mines.
