From seabirds to sea turtles: the fatal toll of plastic revealed
Summary
Scientists studied 10,000 marine animal autopsies to see how plastic affects their survival. They found that even small amounts of plastic can be fatal for animals like seabirds, sea turtles, and marine mammals. This research aims to inform global efforts to protect ocean wildlife from plastic pollution.Key Facts
- Scientists analyzed 10,000 autopsies of marine animals, including seabirds, sea turtles, and marine mammals.
- The study found that ingesting 23 pieces of plastic gives seabirds a 90% chance of dying.
- For marine mammals, 29 pieces of plastic present a similar risk, while sea turtles need to ingest about 405 pieces.
- A small amount of soft plastic, less than the size of a soccer ball, can be fatal to animals like dolphins.
- Rubber is very harmful to seabirds, while soft plastics and fishing debris are dangerous for marine mammals. Both hard and soft plastics are a threat to turtles.
- Nearly half of the studied sea turtles, a third of seabirds, and one in ten marine mammals had ingested plastic.
- The study considered only plastic inside animal stomachs, not other forms of harm like chemical impacts or entanglement.
- Researchers stress the need to reduce plastic production, improve recycling, and clean up existing pollution.
