Scientists estimated that a green sea turtle could contain up to 26.4 grams of plastic, equivalent to approximately 10 ping-pong balls.
What's happening?
The Conversation reported on the prevalence of plastic ingestion among sea turtles. The team built a model based on plastic ingestion data and influential factors.
The goal was to assess the impact of plastic pollution on marine life. Sea turtles were chosen because of their unique vulnerability to the changing oceans. Estimations were made based on a female group of green turtles because adequate data was available on them.
Based on the analysis, it's predicted that roughly 6.6 tons of plastic debris reside within the group of turtles. That's about a garbage truck's worth of plastic. This estimation was used to determine the 10 ping-pong balls' worth of plastic pollution inside a single turtle.
This amount varies based on factors like a turtle's diet and location. Turtles near the equator are exposed to more plastic, while species like leatherback turtles are more likely to consume plastic garbage because plastic debris can be mistaken for their soft-bodied prey.
Why are sea turtles important?
Of the seven sea turtle species, three are classified as vulnerable, one as endangered, and two as critically endangered, according to the Olive Ridley Project.

Losing even one species would disrupt the delicate balance of the oceans. Without them, humans could face fish shortages, unstable coastal regions, and the changing climate.
Like all creatures, turtles are essential to their ecosystems. They help control prey populations, deliver nutrients to coastal vegetation, support coral reef health, act as a food source for other animals, and maintain ocean vegetation.
These findings don't just pertain to sea turtles. All marine life is affected by plastic pollution in the ocean. Countless species are in trouble, leading to a rapidly changing ocean that only worsens the effects of the overheating planet.
Every living thing, from sea kelp to humans, relies on healthy oceans for a stable climate and a healthy planet. Protecting all marine life is crucial to a cooler, cleaner future.

What can be done about plastic pollution in the ocean?
The Conversation has called for more data on the impact of plastic pollution on marine life, further monitoring of ocean life, and standardized reporting on plastic pollution in the oceans. The more data that is made available, the better informed authorities will be when making decisions about protecting the oceans.
Aside from collecting information, everyone can help the turtles and oceans by reducing their plastic use. Avoiding single-use plastics, choosing more sustainable materials when shopping, and recycling responsibly can protect marine life and the planet.
