"The Green turtle is an endangered species.  Most green turtles return to the same nesting site every year. Females crawl onto a beach and dig a nest in the sand. They lay anywhere between 100-200 eggs, but only 1 out of every 100 will survive. Green turtles depend on these beaches for their survival. The Great Barrier Reef protects beaches from being worn away. The reef ecosystem benefits turtles by protecting nests and nesting beaches."
