How can we help save sea turtles from plastic pollution?

Find out what is happening to, and how to help, sea turtles

Sea turtles have roamed the ocean for over 150 million years, but their existence is under threat due to plastic pollution in the ocean. Six of the seven sea turtle species on Earth are currently at risk.

According to the WWF, approximately 20 million tonnes of plastic waste ends up in aquatic ecosystems. Plastic pollution affects sea turtles throughout their lifecycle. From the moment they hatch, they risk injury or death because they ingest or get entangled in plastic.

The effect of pollution on us and our environment is well documented, but the decline of sea turtles could seriously impact our marine ecosystems. Read on to find out why and what you can do to help, both at home and in the field as a turtle conservation volunteer.

Why is it important to save sea turtles?

If sea turtles disappear from the ocean, it wouldn’t only be a huge loss for future human generations, it would also threaten other marine life. 

The Marine Conservation Society discusses why sea turtle species are essential to the health of marine ecosystems, including:

  • The critically endangered Hawksbill Turtle protects coral reefs by grazing on sponges that would otherwise outgrow the corals. If sponges were left to grow unchecked, they would cover the corals and kill the reef.
  • The endangered Green Sea Turtles graze on seagrass beds, which promotes healthier and faster seabed growth. This is important because seagrass beds are homes, nurseries, and feeding grounds to many species of fish and other marine animals.
  • The vulnerable Leatherback Sea Turtle’s main food source is jellyfish. Jellyfish eat larval fish and, if left unchecked, could further reduce the population of fish in the ocean, which are already under heavy stress from overfishing and pollution. 

Protecting sea turtles is essential for a healthy ocean, and we need a healthy ocean to survive.

Why is plastic pollution killing sea turtles?

Plastic pollution affects sea turtles daily, posing several issues throughout a sea turtle’s lifecycle:

  • Laying eggs: Sea turtles lay eggs by digging holes in the sand. Sometimes, there is so much waste on nesting beaches that the female turtles aren’t able to dig through it and give up on laying their eggs. When as few as 1 in 1,000 eggs will survive to an adult turtle, successfully creating a nest is crucial.
  • Access to the ocean: Releasing tiny turtle hatchlings is a dream on many people’s bucket lists. But, if the beach is full of waste, baby turtles can easily get disoriented or entangled and never make it to the water.
  • Eating plastic: When turtles ingest plastic, it can cause injuries to internal organs, intestinal blockages in the stomach, and suffocation. This results in malnutrition, reduced growth rate and even death. Hatchlings and young turtles are especially vulnerable to this as they cannot easily distinguish plastic from prey.
  • Getting entangled: Waste like fishing nets on the surface of the ocean or underwater pose a serious threat to sea turtles as they cannot breathe underwater. If they get entangled and cannot escape, they will drown. Approximately 1,000 turtles die every year after getting entangled in plastic.

The exact number of sea turtles that die as a result of plastic pollution every year is unknown, but researchers estimate that over half of all turtles in the world have ingested plastic.

The good news? You can help.
