Plastic, plankton or ... err, pigs

I've been researching the huge problem of plastic and giant garbage patches in our oceans for an article I'm writing  ... many of us don't know but there are literally large swathes of garbage pollution dotted all over our oceans. Then I stumbled on to this miraculous photo and article, below. 

Every now and then, one needs some light relief, the chance to dream, and then you find yourself drifting away on a boat, feeling enticed in to the water to take a swim with... oink oink ... our lovely pink, grunty friends.  They sure do make up a dramatic contrast with the emerald ripples!

And now I'd better get back to the article.
