Seagrasses are a vital part of the solution to climate change and can store up to twice as much carbon as the world's temperate and tropical forests, new research indicates. The study was published yesterday, May 20, in the journal Nature Geoscience. ..."One remarkable thing about seagrass meadows is that, if restored, they can effectively and rapidly sequester carbon and reestablish lost carbon sinks," study researcher Karen McGlathery, of the University of Virginia, said in a statement.
