They often seem to eat plastic unintentionally, risking their health, but in some cases may do so on purpose to induce vomiting up of other undigested foods. Since the 1950s, humanity has produced an estimated 8.3bn tons of plastic, adding a further 380m tons to this amount each year. Only 9% of this gets recycled. The inevitable result is that plastic is everywhere, from the depths of the oceans to the summit of Everest – and notoriously, inside the tissues of humans and other organisms. The long-term effects of ingested plastic on people aren’t yet known. But in rodents, ingested microplastics can impair the function of the liver, intestines, and exocrine and reproductive organs. Especially at risk of ingesting plastic are scavenging birds. For example, New World vultures regularly forage at landfills, and have been observed to leisurely pick at synthetic materials such as boat seats, rubber seals, or roofs.
