The effort to feed thousands of pounds of lettuce to starving manatees in Florida manatees officially ended for the winter season Wednesday, as deaths of the marine mammals appear to be slowing despite the long-term threat of pollution to their main food source, seagrass.
State and federal wildlife officials said during an online news conference that just under 400,000 pounds (181,000 kilograms) of lettuce was provided to hundreds of manatees at a warmwater power plant site along the east coast where they typically gather for the winter.
