27 Jul 2020 - The Guardian - Plastic waste flowing into the oceans is expected to nearly triple in volume in the next 20 years, while efforts to stem the tide have so far made barely a dent in the tsunami of waste, research shows.
Governments could make drastic cuts to the flow of plastic reaching the oceans through measures such as restricting the sale and use of plastic materials, and mandating alternatives, but even if all the most likely measures are taken it would only cut the waste to little less than half of today’s levels, the analysis found.
Previous estimates put the amount of plastic reaching the oceans each year at about 8m tonnes, but the true figure is much higher at about 11m tonnes, according to the paper published in the journal Science.
If current trends continue, the amount of plastic waste polluting the oceans will grow to 29m tonnes a year by 2040, the equivalent of 50kg for every metre of coastline in the world.
