Coastal seagrass can store more heat-trapping carbon per square mile (kilmometre) than forests can, which means these coastal plants could be part of the solution to climate change, scientists said in a new study.
Even though seagrasses occupy less than 0.2 percent of the world's oceans, they can hold up to 83,000 metric tons of carbon per square kilometer, a global team of researchers reported Sunday in the journal Nature Geoscience.
That is more than twice the 30,000 metric tons of carbon per square kilometer a typical terrestrial forest can store.
