#PlasticPollution is more than #waste New resources from ANH Academy and FAO reveal how the impacts of pollution across the plastics lifecycle cascade across agrifood systems, the environment, plants, animals and human health. openknowledge.fao.org/handle/20.50...
openknowledge.fao.org
Plastic pollution in agrifood systems and One Health - impact pathways and policy implications
Plastic pollution is pervasive across agrifood systems, creating interconnected illustrative pathways of exposure and harm across environmental, plant, animal and human systems. This technical brief illustrates these linkages through four interconnected impact pathways and demonstrates that plastic pollution is a cross-cutting threat to ecosystem integrity, animal health and welfare, food safety, food security and human well-being. A One Health approach provides a practical framework to connect these impacts and support integrated, preventive and adaptive responses across agrifood systems.

“Plastic pollution has no borders,” states C.K. Pham, lead author on research on #plastic pollution in the Azores. It is a “tragedy of the commons” says @tonyrwalker1.bsky.social.

Title, journalist’s name, photograph of plastic pollution along the coastlines of the Azores, and first paragraph from a news article about ghost fishing gear, particularly gear from Nova Scotian fisheries, found in the Azores and the need for international policy on plastic pollution

Antarctica's first dinosaur fossil confirmed from 1985 Antarctic expedition
A bone collected by a British Antarctic Survey (BAS) geologist nearly 40 years ago has been formally described as the first dinosaur fossil ever found on the Antarctic continent. The vertebra was discovered by Dr Mike Thomson, a BAS geologist, during a 1985 expedition to James Ross Island on the Antarctic Peninsula. The expedition’s aim was to map rock layers to help future geologists and palaeontologists date fossil finds across the region. At the time, Thomson recorded it as a large reptile but it has only now been formally identified as belonging to a dinosaur. Finding the dinosaur bone in our collection Dr Mark Evans, palaeontologist and manager of the geological collections and labs at BAS, said: “This fossil was found by Dr Mike Thomson, one of the true pioneers of Antarctic geology. His work helps us date all fossil finds across the Antarctic Peninsula today. When I first spotted this bone in our collections a few years ago, I suspected it was a dinosaur. After looking at it properly, I thought it was probably a titanosaur tail vertebra. Looking back at Mike’s notebooks, he knew it was a large reptile so it’s very special to confirm his find 40...
