Most of us are aware that plastic finding its way in oceans and waterways is a growing ecological problem. Plastics have been found throughout the marine food-chain, in the tissue and digestive tracts of all manner of creatures from whales to tiny aquatic worms.Julia Reisser from the University of WA is studying pollution in Australian waters and has found each square kilometre of seawater carries an average of 4000 pieces of plastic. And it’s not only the plastics themselves that cause problems, but that they attract and concentrate oil-based pollutants in the sea, adding to the toxic load on the unfortunate sea creatures that digest them.
Reisser pin-points single-use plastic containers as being a major source of marine pollution, and encourages efforts to reduce their usage. Yet another reason to ditch the bottled water and soft-drinks, and go tap!
