Studie: Kloden tåler ikke mer mikroplast

PLASTFORURENSNING: Vårt plastforbruk har spredt mikroplast til alle verdens hjørner. En ny studie slår fast at det ødelegger og endrer naturen for godt.

FILE - This May 19, 2010, file photo shows a blue rectangular piece of microplastic on the finger of a researcher with the University of Washington-Tacoma environmental science program, after it was found in debris collected from the Thea Foss Waterway, in Tacoma, Wash. Tiny bits of broken-down plastic smaller than a fraction of a grain of rice are turning up everywhere in oceans, from the water to the guts of fish and the poop of sea otters and giant killer whales. Yet little is known about the effects of these "microplastics" - on sea creatures or humans. (AP Photo/Ted S. Warren, File)

SMÅ PROBLEMER: Mikroplast er plast som er mindre enn fem millimeter i diameter. Når plasten blir enda mindre, omtales den som nanoplast. (Ted S. Warren/AP)
