"Seagrasses are flowering plants that live submerged in salty water and perform vital ecosystem services that help us and the food-webs that rely on them. For example, seagrasses capture and store more atmospheric carbon (per unit area) than many terrestrial plants, they act as nursery areas for important fishery species, and provide coastal protection against things like erosion and storm surges," Dr Ryan Pearson.
"Under the Paris Climate Agreement, nations need to show how they intend to reduce carbon emissions. Protection of mangroves is an important climate action, because mangroves accumulate three to ten times more carbon than most ecosystems on the planet. But actions for reducing emissions by reducing loss of mangrove forests can be contentious."
