I wish I could remember the details, but I do remember a journalist, or possibly a scientist, who said there was a "plastic island" in the Pacific later saying she regretted describing it that way. It may also have been that she didn't use that term but that her explanation of the problem was misrepresented.
It was depressing because a plastic island is bad enough. I assumed it hadn't been cleaned up because, even if someone were willing, you'd still have to put all that plastic somewhere.
The fact that plastic--enough to make several islands--is found throughout the world's oceans, not necessarily all clumped together, makes the problem even more depressing.
