Earth day, plastic and a man-made disease

With at least 10 million tonnes of plastic being dumped into oceans each year, experts have long been warning about an environmental plastic cataclysm. Now it has been shown that animals are dying from a new man-made disease: plasticosis.

Coined in 2023, the term shows just how prevalent and toxic our plastic garbage has become to animals. Not only are whales, sea turtles, fish and birds being poisoned by plastic. It has made its way into our own diet. In a study in the New England Journal of Medicine, Dr. Raffaele Marfella et al, has shown that microplastics were detected in the plaque in veins of people who had cardiac problems.

In the animal world, seabirds seem to be particularly vulnerable. Plasticosis involves plastic ingestion and is causing damage to the stomach, scar tissue, and eventual death. It starves the birds who already have plastic-filled stomachs and is thought to be as lethal as asbestos.

In order to find out why birds were so thin and were dying in an Australian wildlife preserve, Hayley S. Charlton-Howard et al, examined 21 adolescent Flesh-footed Shearwater birds from Lord Howe Island in 2021.  Some had already died, while others had very low body mass. Their stomachs were found to not only to contain pumice, which is naturally used by birds to break down their food, Charlton-Howards’ findings published in the Journal of Hazardous Materials in 2023, were alarming for the seabirds:
