"Blood tests on migratory chicks fed plastics by their parents show neurodegeneration, as well as cell rupture and stomach lining decay"

"Ingesting plastic is leaving seabird chicks with brain damage “akin to Alzheimer’s disease”, according to a new study – adding to growing evidence of the devastating impact of plastic pollution on marine wildlife.

Analysis of young sable shearwaters, a migratory bird that travels between Australia’s Lord Howe Island and Japan, has found that plastic waste is causing damage to seabird chicks not apparent to the naked eye, including decay of the stomach lining, cell rupture and neurodegeneration.

Dozens of the chicks – which spend 90 days in burrows before making their first journey – were examined by researchers from the University of Tasmania. Many had mistakenly been fed plastic waste by their parents and built up high levels of plastic in their stomachs."
