Seagrasses cover shallow coastal regions of temperate and tropical seas worldwide. Seagrass meadows form the basis of an essential ecosystem that is home to numerous animals, including endangered species of sea turtles, seahorses, and fishes. They also protect the coasts from erosion and sequester millions of tons of carbon dioxide from the atmosphere every year. But seagrass meadows also emit greenhouse gasses, especially methane, which has a much stronger effect on our climate than carbon dioxide.
