'Plasticosis': Researchers Discover New Digestive Disease Sickening Seabirds
"This study is the first time that stomach tissue has been investigated in this way and shows that plastic consumption can cause serious damage to these birds' digestive system," the paper's lead author said.
A newly discovered disease is sickening seabirds, and it's not caused by a virus or bacteria—it's caused by ingesting the increasingly ubiquitous bits of plastics contaminating land, air, and sea.
That's the conclusion of a recently published study in the Journal of Hazardous Materials, with researchers calling the "novel, plastic-induced fibrotic disease" plasticosis.
According to the paper's abstract:
Highly impacted by plastic ingestion, flesh-footed shearwaters (Ardenna carneipes) are thus an apt species to examine these impacts in an environmentally relevant manner. A Masson's Trichrome stain was used to document any evidence of plastic-induced fibrosis, using collagen as a marker for scar tissue formation in the proventriculus (stomach) of 30 flesh-footed shearwater fledglings from Lord Howe Island, Australia. Plastic presence was highly associated with widespread scar tissue formation and extensive changes to, and even loss of, tissue structure within the mucosa and submucosa. Additionally, despite naturally occurring indigestible items, such as pumice, also being found in the gastrointestinal tract, this did not cause similar scarring. This highlights the unique pathological properties of plastics and raises concerns for other species impacted by plastic ingestion.
"While these birds can look healthy on the outside, they're not doing well on the inside," study co-author Alex Bond, who is the senior curator in charge of birds at the U.K.'s Natural History Museum in London, told The Guardian. "This study is the first time that stomach tissue has been investigated in this way and shows that plastic consumption can cause serious damage to these birds' digestive system."
Previous studies have found that around 90% of all seabirds have ingested plastics. Marine conservationists argue that reduced plastics consumption and targeted efforts to keep plastics out of the Earth's oceans are the most effective means of curbing the crisis.
FINAL DAY! This is urgent.
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission from the outset was simple. To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It’s never been this bad out there. And it’s never been this hard to keep us going. At the very moment Common Dreams is most needed and doing some of its best and most important work, the threats we face are intensifying. Right now, with just hours left in our Spring Campaign, we're still falling short of our make-or-break goal. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Can you make a gift right now to make sure Common Dreams not only survives but thrives? There is no backup plan or rainy day fund. There is only you. —Craig Brown, Co-founder |
