Protecting Seagrass Will Help Save Our Oceans

By United Nations Environment Programme (UNEP). 

About 0.1 per cent of the ocean’s floor is covered in lanky green flowering plants known as seagrasses.

Their often-sprawling meadows purify ocean water, shelter fish and provide food for thousands of marine species. But seagrass habitats have been in decline since 1930, with 7 per cent of them disappearing each year, according to United Nations Environment Programme (UNEP) research.

Along with being a haven for marine life, seagrass sediment is one of the planet’s most efficient carbon stores and prevents it from becoming a planet-warming greenhouse gas.

Now, researchers at the Max Planck Institute for Marine Microbiology in Bremen, Germany, a one-time coordinator of a European Union-UNEP project, have discovered how seagrasses store carbon.
