At least 200 tons of waste is removed from the River Thames each year, much of which is plastic pollution and microplastic.
A study in 2020 revealed that the Thames has some of the highest recorded levels of microplastics for any river in the world.
Scientists have estimated that, in some places, 94,000 microplastics per second flow down the river.
Although the full impact to human health is unknown, microplastics can cause damage to human cells and have been detected in human blood and lungs.
So, from zero waste stores across the city to plastic sculptures in the street, how are communities in London tackling plastic pollution?
