The Carbon Cycle is a biogeochemical cycle that plays a prominent role in how the planet and its inhabitants function. A major sink for carbon are the forests around the world, however, a recent study indicates that seagrasses are able to sequester the same if not more carbon than forests. About 30,000 metric tons of C/sq. km is stored in your typical forest. Seagrass ecosystems can store up to 83,000 metric tons of C/sq. km. Despite their limited range, 0.2% of the planet’s oceans, they account for more than 10% of carbon sequestered by the ocean per year. The lead author, Dr. James Fourqurean of Florida International University, said that they found that some seagrass beds had stored carbon for thousands of years as they continue to build on the carbon that they have stored. He warns that the seagrass beds are disappearing rapidly, which will alter the balance of the Carbon Cycle. However, once a seagrass bed has been restored, it can catch back up where it left off.  - JB For more info: http://phys.org/news/2012-05-seagrasses-carbon-forests.html
