Last December, while diving in the Misool area of western Papua, we entered an island cave that went upward into a fully enclosed chamber above water level. The chamber was about 50 meters across and about the same in height. There were 2 small openings less than 1/2 meter that let in light. To my amazement there was a dozen or so pieces of plastic debris - parts of coffee cups, egg cartons, a sandle, etc. floating around on the surface!
This area is about as far from civilazation as you can get and here was more plastic trash! Amazng that it even washed in through the 2 small portals.
Last year, there was a special on one of the educational TV stations on plastic waste being trapped in a giant circular water movement in the central Pacific and washing up on the far northern Hawaiian Islands. Images were shown of piles of trash and nets as high as 2 meters.
More disturbing is this recent article http://www.news.com.au/story/0,23599,23156017-38196,00.html
that indicates that plastic trash is breacikg up into smaller pieces and turning into a "soup".
Well, I guess that the move 20 years ago to save the trees is a resoundiing success!
