Impact Statement

Natural solution · active

meadows cover just 0.1 percent of the world's seafloor but store 11 percent of the organic carbon buried in the ocean, NOAA says. They are also nurseries: a single acre of seagrass can support almost 40,000 fish, and animal abundance in grassbeds is 10 to 100 times higher than over nearby sand.
