Scientists Say Humans Helped Chesapeake Bay Grass Resurgence

"Grass is back and thriving in the Chesapeake Bay, and that bodes well for not only your dinner plate but the future of human-led efforts to restore polluted ecosystems.

The bay is seeing its greatest growth of underwater grasses in almost half a century, according to a study in the Proceedings of the National Academy of Sciences.

Scientists and conservationists have long devoted efforts to cleaning up the bay and restoring the vegetation that serves as a “sentinel” for its overall health. Recently they evaluated how those efforts played out over the past three decades."
