Krill found to break down microplastics – but it won't save the oceans

Digestion of plastic into much smaller fragments 'doesn't necessarily help pollution', Australian researchers say

A world-first study by Australian researchers has found that krill can digest certain forms of microplastic into smaller - but no less pervasive - fragments.

The study, published in Nature Communications journal on Friday, found that Antarctic krill, Euphausia superba, can break down 31.5 micron polyethylene balls into fragments less than one micron in diameter.
