Great Lakes microplastics concentrations exceed safe levels for wildlife

Nearly 90 percent of water samples taken from the Great Lakes over the last 10 years exceed safe levels for wildlife. Researchers from the University of Toronto and the Winnipeg-based International Institute for Sustainable Development came to this conclusion after conducting a comprehensive review of microplastics studies. At the levels surveyed, the researchers say fish and other aquatic wildlife are at risk of ingesting enough microplastics to fill their guts, diluting their regular food and its nutritional value.
