In Baltic Sea, citizen divers restore seagrass to fight climate change

Seagrasses store more than twice as much carbon from planet-warming carbon dioxide (CO2) per square mile as forests do on land, according to a 2012 study. The plants also help support fisheries and protect coasts from erosion. Europe alone lost one third of its seagrass areas between the 1860s and 2016, one 2019 study found, releasing carbon into the atmosphere and speeding up global warming.
