Plastic nurdles have been found in 84% of important nature sites surveyed in the UK.

Nurdles are tiny pellets that the plastics industry uses to make larger products. They were found in 168 of 195 sites of special scientific interest (SSSIs), so named because of the rare wildlife they harbour. They are given extra protections in an effort to protect them from pollution.

The environmental charity Fidra, however, has been running nurdle hunts at SSSIs across the UK since 2013, and found pellets in 84% of them.
