How do we stop plastic trash entering the Hauraki Gulf?
Any beach walk shows it's a pressing problem, and one Aucklanders must solve.
Plastic is washed into stormwater drains, blown into water courses, dumped on the foreshore or at sea ... one way or another, it finds its way into the water and then breaks up, potentially to be ingested by seabirds, fish and shellfish.
Last month, on this page, we appealed for ideas and received a larger response than expected.
Several suggested banning plastic bags. One person wanted to culture "plastic-eating microbes", another to build trash sculptures, "to draw attention to the issue".
