Scientists tested the stomach contents of beached northern fulmars (an abundant, gull-like seabird) in British Columbia, Oregon, and Washington State to come to their conclusions about world pollution levels. The study, conducted between 2009 and 2010 and published in the Marine Pollution Bulletin, found that 92.5% of beached northern fulmars sampled had some amount of plastic in their digestive tracts. One bird had a whopping 454 pieces of plastic in its stomach.
