The world’s largest collection of marine debris information has identified Australia’s coastal rubbish is mainly plastic from Australian sources.
In a report released today, CSIRO scientist Denise Hardesty says her team surveyed sites approximately every 100 km along the Australian coastline.
“We found about three-quarters of the rubbish along the coast is plastic,” she says. “Most is from Australian sources, not the high seas, with debris concentrated near cities.”
She says the density of plastic in Australian waters ranges from a few thousand pieces of plastic per square kilometre to more than 40,000 pieces. (…)
