Krill Kill?

Researchers at the University of Tasmania have identified micro-particles of plastic in an ice core taken from Antarctica in 2009 (https://www.theguardian.com/world/2020/apr/22/microplastics-found-for-first-time-in-antarctic-ice-where-krill-source-food). The core is from a region where krill crustaceans feed and, their feeding technique, suggests that the plastics will be ingested. Many organisms, such as the mighty baleen whales, filter feed on the krill, so it is highly likely that the plastics will influence entire food chains. It would be interesting to determine whether the concentration of micro-plastics is increasing in more recent ice samples.
