Full scale of plastic in the world's oceans revealed for first time
Over five trillion pieces of plastic are floating in our oceans says most comprehensive study to date on plastic pollution around the world
More than five trillion pieces of plastic, collectively weighing nearly 269,000 tonnes, are floating in the world’s oceans, causing damage throughout the food chain, new research has found.
Data collected by scientists from the US, France, Chile, Australia and New Zealand suggests a minimum of 5.25tn plastic particles in the oceans, most of them “micro plastics” measuring less than 5mm.
The volume of plastic pieces, largely deriving from products such as food and drink packaging and clothing, was calculated from data taken from 24 expeditions over a six-year period to 2013. The research, published in the journal PLOS One, is the first study to look at plastics of all sizes in the world’s oceans.
Large pieces of plastic can strangle animals such as seals, while smaller pieces are ingested by fish and then fed up the food chain, all the way to humans.
