85 Australian Microplastic Assessment Project Research Director Dr Scott Wilson looks for microplastics amongst organic matter inside a container on Manly Cove Beach in Sydney, Australia. Reuters SYDNEY, April 21 Equipped with just a pan and sieve, a group of amateur scientists comb the beach looking for tiny bits of plastic that are near invisible to the naked eye but belie their threat. "There's evidence that we are breathing it, ingesting it in our foods. There's lots of studies showing it's in our water, it's in our food products," said Scott Wilson, research director of the Australian Microplastic Assessment Project (AUSMAP). "There's a good chance all of us will have some type of microplastic in our bodies at some stage - the question is what harm is that having?"
