Seal poo reveals plastic’s path in the sea


Every year, around 236,000 tonnes of microplastics (tiny fragments of plastic from broken down plastic bags, bottles and other plastic products) end up in our oceans. Researchers have long feared that these microplastics could enter the food chain, eventually being ingested by humans eating fish and other seafood. A 2017 study in the UK examining poo samples of seals and mackerel found proof that microplastics are indeed transferred from prey to predator. Scientists at Ghent University in Belgium claim that shellfish lovers eat up to 11,000 plastic fragments in their seafood every year. Plastic in our oceans has become a global crisis. It is expected to outweigh fish by 2050.
