Seagrass 'Neptune balls’ sieve millions of plastic particles from water, study finds

Researchers counted particles in seaballs that washed up on beaches in Spain

Underwater seagrass in coastal areas appear to trap plastic pollution in natural bundles of fibre known as Neptune balls", researchers have found.

With no help from humans, the swaying plants - anchored to shallow seabeds - may collect nearly 900m plastic items in the Mediterranean alone every year, a study reported in the journal Scientific Reports said.
