What Do Green Sea Turtles Do For The Environment? 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 green sea turtles went extinct? If sea turtles went extinct, dune vegetation would lose a major source of nutrients and would not be as healthy and would not be strong enough to maintain the dunes, resulting in increased erosion. If sea turtles went extinct, both the marine and beach/dune ecosystems would be negatively affected.
What do green sea turtles do? Green turtles, like all sea turtles, are reptiles and must surface to breathe and lay their eggs on land. Green turtles migrate hundreds to thousands of kilometers each way between their foraging grounds and nesting beaches.
Why are hawksbill turtles important to the ecosystem? Hawksbills help maintain the health of coral reefs. As they remove prey such as sponges from the reef’s surface, they provide better access for reef fish to feed. They also have cultural significance and tourism value.

What would happen if hawksbill turtles went extinct?
Hawksbill turtles eat sponges, preventing them from out-competing slow-growing corals.

What year will sea turtles go extinct?

How many green turtles are left?
Population Estimate*: Between 85,000 and 90,000 nesting females.
Do plastic straws really kill turtles?
In 2011, the National Oceanic Atmospheric Association found that plastic debris accumulates pollutants such as PCBs up to 100,000 to 1,000,000 times the levels found in seawater. Marine life, including sea turtles, can be harmed by ingesting plastic straws and brokendown plastic polluting our ocean and waterways.
How many sea turtles are left in the world 2020?
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.
How many animals does plastic kill a year?
The Problem: Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean (UNESCO Facts & Figures on Marine Pollution). Currently, it is estimated that there are 100 million tons of plastic in oceans around the world.

Why are plastic bags dangerous to sea turtles?
Sharp plastics can rupture internal organs and bags can cause intestinal blockages leaving turtles unable to feed, resulting in starvation. Even if they survive, consuming plastic can make turtles unnaturally buoyant, which can stunt their growth and lead to slow reproduction rates.
