Biologists take drastic measures to save Florida manatees at risk of starvation
Last year was the deadliest on record for manatees, many of whom starved to death because of a lack of seagrass. A die-off is happening again this year, and federal and state officials as well as volunteers in Florida are trying to save starving manatees with a pilot-feeding project this winter. But as Miles O'Brien reports, there are also larger environmental problems in the water.
