Plastic Bagging a Catch?

A review of 655 scientific articles by Australia's CSIRO, has confirmed that plastic bags and other flexible packaging are lethal ocean pollutants. They kill dolphins, seabirds, turtles and even whales (https://www.theguardian.com/environment/2020/dec/14/deadliest-plastics-bags-and-packaging-biggest-marine-life-killers-study-finds ). This carnage occurs on a worldwide basis. The actual plastic items that are most deadly, however, varies from species to species. Discarded fishing line, latex gloves (a plastic 'bloom' in the Covid-19 pandemic) and baloons are common causes of death, following mistaken eating by marine birds and mammals. Just a word of caution. Awful although these deaths are, they occur in prominent organisms that can relatively easily be located. The impact of microplastic pollutants might well be worse but would not be so obvious. Their impacts would be on animals nearer the start of food chains.
