The title sounds like a contradiction, after all who would want to go to a beach made of plastic? Well it appears that we might not have a choice, given the amount of plastic floating around in the oceans today.
The BBC is currently broadcasting a series called Tropic of Cancer, in which Simon Reeve travels along the line of that name. In the last episode, to be broadcast tomorrow, he ends up in Hawaii, where they found a beach with more rubbish than sand.
The biggest trouble was the plastic breaking down into smaller and smaller grains, until it merges into the sand, impossible to remove (see below).
You can get a taster from this extract on the BBC site.
Sorry to keep blogging downer environmental posts, but this bugs me: it just isn't right.
