Here’s what we know:

Plastic in all 13 rivers Greenpeace  tested: Exe, Thames, Severn, Great Ouse, Trent, Mersey, Aire, Derwent, Wear, Conwy, Wye, Clyde and Lagan. The River Mersey was proportionally more polluted than the Great Pacific Garbage Patch – containing equivalent to 2 million pieces of microplastic per square km.
Five out of 13 rivers contained microbeads – which were partially banned in 2017.

Here’s what we need:

An Environment Bill that sets ambitious targets to radically reduce single-use plastic, and restores our natural world. River Mersey is more polluted than the Great Pacific Garbage Patch. But sadly it’s true, the results of our survey of rivers across the UK are out and Greenpeace found plastic in every single river tested.
If it wasn’t clear before, it is now – we must radically reduce throwaway plastic.
