Scientists suggest risky plan to save manatees from red tide

Within the past decade, the toxins produced by Florida red tide algae have killed 437 manatees after they ate grasses full of red tide toxins on their late-winter migration from rivers to the Gulf of Mexico; researchers propose opening the floodgates that connect the Caloosahatchee River to Lake Okeechobee and letting the water flow through if red tide is headed toward the river before the manatees migrate - Aug. 3, Sarasota Herald Tribune
