     • Rivers are a major source of plastic waste in the oceans. We estimate that 1000 rivers, represented by the red dots, are accountable for nearly 80% of global annual riverine plastic emissions, which range between 0.8 – 2.7 million metric tons per year, with small urban rivers amongst the most polluting.

   How much plastic does a river emit?

   • They found that rivers emitted around 1 million tonnes of plastics into the oceans in 2015 (with an uncertainty ranging from 0.8 to 2.7 million tonnes). Around one-third of the 100,000 river outlets that they modeled contributed to this. The other two-thirds emitted almost no plastic to the ocean.

   How much plastic flows into the oceans through rivers?

   • The publication sheds new light on where and how much plastic flows into the oceans via rivers. With the help of new measurements and modeling, the study shows that 1000 rivers shed almost 80% of plastic emissions. This number is 100 times more than the 10 rivers that were previously thought to be responsible for most of the pollution.

   Are rivers causing ocean plastic pollution?

   • Rivers are the primary sources of plastic in the oceans. These new findings indicate that ocean plastic pollution is caused by a greater number of small and medium-sized rivers, defined by a set of geographic factors that determine the highest contribution to the inflow of plastic into our oceans.

   How much plastic does a river dump a year?

   • The results, published last November in Environmental Science & Technology, show that rivers collectively dump anywhere from 0.47 million to 2.75 million metric tons of plastic into the seas every year, depending on the data used in the models.

   How does plastic get into the ocean?

   • There are multiple ways plastic comes into direct contact with the sea including the wind, drains and illegal dumping. Rivers are the primary conduit, however, with a staggering 90 percent of all plastic waste entering the world's oceans eminating from just ten rivers.

   How much plastic is in the oceans a year?

   • One to two million tonnes of plastic enter our oceans yearly, affecting wildlife and ecosystems. Improving the management of plastic waste across the world – especially in poorer countries, where most of the ocean plastics come from – is therefore critical to tackling this problem.

    May 1, 2021 · Most of the plastic in our oceans comes from land-based sources: by weight, 70% to 80% is plastic that is transported from land to the sea via rivers or coastlines. 1 The other 20% to 30% comes from marine sources such as fishing nets, lines, ropes, and abandoned vessels. 2
