Why Do We Need to Raise Seagrass Awareness?

It's the end of March as the month for seagrass. I would like to write down a little about how lovely seagrass to be part of our ecosystem. For common people seagrass is unfamiliar thing, though they know it's only grass in the sea. Well, nothing is wrong with the perception. It is grass, same with the grass in the land but it lives in salt water. Then why we need to be aware of this grass?
