A recent study of coastal seagrasses published in the Proceedings of the National Academy of Sciences found that 58 percent of seagrass meadows are in decline.  Seagrass meadows provide important habitat for ocean life and help decrease the impact of sediment and nutrient pollution.  Since 1980, 29% of seagrass has disappeared, but even more troubling is the speed with which seagrass is disappearing.  According to the study, the rate of loss has increased from 0.9% a year, before 1940, to 7% a year, since 1990.  For more information on this study, see ABC Science.
