There's a lot more man-made garbage afloat in the Pacific Ocean than we had thought. Sixteen times more. A patch twice the size of France.
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 Nature 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.
The analysis, conducted by boat and air surveys taken over two years, found that pollution in the so-called Great Pacific garbage patch is almost exclusively plastic and is “increasing exponentially”. Microplastics, measuring less than 0.5cm (0.2in), make up the bulk of the estimated 1.8tn pieces floating in the garbage patch, which is kept in rough formation by a swirling ocean gyre.
