How Are Sea Turtles Important? What we do know is that sea turtles—even at diminished population levels—play an important role in ocean ecosystems by maintaining healthy seagrass beds and coral reefs, providing key habitat for other marine life, helping to balance marine food webs and facilitating nutrient cycling from water to land.
What would happen if sea turtles went extinct?

How do sea turtles help the economy? Green turtles are largely herbivorous, and their constant grazing on sea grasses increases the healthiness and growth rate of seagrass beds.
