Seagrasses grow in salty and semi-salty (brackish) shallow waters worldwide. A wide varietyof species live in and around seagrasses. Green sea turtles feed on seagrasses, while many different species of small fish, crabs, and shrimp use seagrasses for shelter. An increase in ocean pollution, in addition to overfishing, has reduced the number and type of seagrasses worldwide. In one area where the number of seagrasses has declined, scientists have decided to plant a new area of seagrass. Explain if this would have a negative or positive effect on the ecosystem. Include ideas about biodiversity, stress, and overall health of the ecosystem in your response.
