One of the most powerful natural tools we have to protect our environment lives out of sight, just beneath the ocean surface: seagrass. It exists on every continent except Antarctica, serves as an essential habitat for fish, and defends coastlines from erosion while sequestering carbon that would otherwise contribute to a warming climate. In fact, scientists estimate that seagrass meadows are responsible for 10% of the carbon stored in the ocean each year. 

But nations can't benefit from this natural resource without first knowing how much they have. In this episode, Pew expert Stacy Baez discusses the importance of seagrass mapping around the world. And Annike Faure of the Seychelles Conservation and Climate Adaptation Trust explains how she helped get her country excited about seagrass. She also highlights why raising public awareness for seagrass—and clearing up misconceptions—is just as important as mapping it.
