The patch of detritus is more than twice the size of France and is up to 16 times larger than previously estimated.

An enormous area of rubbish floating in the Pacific Ocean is teeming with far more debris than previously thought, heightening alarm that the world’s oceans are being increasingly choked by trillions of pieces of plastic.

The sprawling patch of detritus – spanning 1.6m sq km, (617,763 sq miles) more than twice the size of France – contains at least 79,000 tons of plastic, new research published in Scientific Reports has found. This mass of waste is up to 16 times larger than previous estimates and provides a sobering challenge to a team that will start an ambitious attempt to clean up the vast swath of the Pacific this summer.
