Move over, kale. There’s a hip new veggie in town, and this one isn’t just good for the body, it’s good for the world. Meet kelp.

Kelp, otherwise known as seaweed, has long been a staple of diets in Asia, but the kelp industry is catching on in North America as well. You can now spot it on grocery shelves, in hospitals, and in schools.

NPR reports that in Maine, cod, shrimp, and sardine fisherman have been swayed to switch from those shrinking industries to kelp farming, growing seaweed that retails at $15 a pound. Some are even getting financial aid from local economic development agencies and the National Oceanic and Atmospheric Administration (NOAA).
