Nobody really knows how much plastic is in the world’s rivers or where it accumulates.
Estimates of the amount of plastic entering the oceans from rivers range from 0.057 million to 2.75 million tonnes a year, or 10 to 250 bin lorry loads per day.
Plastic pollution can cause devastating effects to river ecosystems and the invertebrates, fish and mammals that live there. So improving these plastic estimates is vital.
