Last year, more than 1,000 manatees died along Florida's waters - a record-breaking number. They are starving to death because runoff pollution from farms, fertilizers from people's yards, among other things, eventually end up in the water. That runoff creates more intense algae blooms, which block sunlight from reaching seagrasses, killing off huge swaths of them. Now, there is a pilot program that hopes to restore some of the seagrass beds.
