Yesterday, after 30 years I returned to The Wash (see original pic's here). The emerging issue of the day was global warming. Today, 'one' of the issues is plastic in the oceans. The amount of plastic present didn't seem huge however, on consideration I was never more than 10 feet from a plastic bottle on a 5 mile walk and the wash is about 90 square miles of tidal flats, that adds up to a lot of plastic.
What it should look like
