John,

Manatees are wasting away.

The lush sanctuaries where these gentle "sea cows" once thrived are transforming into underwater deserts, leaving manatees to starve as they dig desperately through the sand for seagrass, their main food source.

Some manatees have even been found dead with sand in their stomachs -- because there's just no seagrass to be found.1

But how did this happen? And what can we do to stop it?

The impacts of this cycle can be devastating. In Indian River Lagoon, where manatees once ate their fill in rich green meadows of seagrass, algal blooms carpeted the water's surface, and 58% of the lagoon's seagrass died as a result, leaving those manatees desperate and famished.3

Like so many of our biggest environmental challenges, the best way to tackle this problem is at the source.

If we're going to save the manatees before they're gone for good, we have to start on dry land by reducing our use of chemicals and fertilizers that cause this problem, and holding polluters accountable for contributing to this nitrogen-rich runoff.

Thank you,

Lisa Frank
Executive Director
