Norwegians are becoming concerned about the 'huge concentrations' of microscopic plastic waste in their Arctic sea ice and its potential effects on fish stocks (www.bbc.co.uk/news/science-environment-42947155). Melting a litre of sea ice apparently reveals an average of more than 200 small pieces of plastic that can be ingested by marine organisms.They point out that, as plastics float, they are incorporated in the sea ice as the surface layers freeze. This really is the Anthropocene era!
