The oceans are full of our plastic ? here?s what we can do about it
By Britta Denise Hardesty, CSIRO and Chris Wilcox, CSIRO
The Australian government has a ?threat abatement plan? which aims to
save marine animals from being harmed by rubbish. We set out to inform
this plan by developing a better understanding of where exactly this
rubbish comes from and how exactly it harms wildlife.
We surveyed the entire Australian coast at 100 km intervals, with help
from school groups and citizen scientists. We found that our shorelines
are littered with debris. About three-quarters of it is plastic and,
although there are some large items, 95% of the items are just a few
centimetres across, or smaller.
In Australian waters, you can expect to find anything from a few
thousand to more than 40,000 pieces of plastic per square kilometre.
