What would happen if green turtles went extinct? If turtles were to ever go extinct, seagrasses would eventually die off and this would in turn affect the marine life and eventually human life as well. Beaches have a very fragile ecosystem in that they don’t get many sources of nutrients hence there is very little vegetation.
Why are green sea turtles important to the ecosystem? Sea turtles — even at diminished population levels — play an important role in ocean ecosystems. When green sea turtles graze, they increase the productivity and nutrient content of seagrass blades. Hawksbills allow other species, such as coral, to colonize and grow by removing sponges from reefs.
Why does it matter if Green sea turtles go extinct? If sea turtles go extinct, it will cause declines in all the species whose survival depends on healthy seagrass beds and coral reefs. That means that many marine species that humans harvest would be lost.
