At last, some good research findings on the problem of plastic rubbish in the ocean. But as is often true with new findings, new questions open up:
1. The world’s 10 worst ocean plastic polluters do not include Australia.
How much impact can our attempts to fight the problem really have?
2. The top 10 marine debris items are overwhelmingly dominated by footwear/thongs, bottle tops/caps, coloured plastic bottles, and clear plastic bottles. Plastic bags, to which so
much attention has recently been focused in Australia, rank fifth, a comparatively slim slice of the debris pie. Are we attacking the wrong problem?
3. How does that plastic debris end up in the ocean? Your article suggests that it may be things tossed overboard from boats.
It is not obvious how plastic bags, presumably put into the rubbish and hauled to be buried in dumping areas, can be a cause.
Let’s have more research studies into this massive problem and articles like yours presenting those research findings. ROBERT L. GLASS,TOOWONG, QLD
