Although eelgrass and other sea grasses are not a direct source of food for humans, their presence is very important to the health of a marine estuary. Grasses provide shelter and nourishment to many different kinds of life and are valuable indicators of clean, clear water. In places where pollution has damaged or destroyed vibrant eelgrass beds, people are working hard to plant new grasses and establish these beds. |
