This picture was taken in Indonesia by Justin Hofman. It appears in the June issue of "The National Geographic Magazine" in a feature that looks at the impact of waste plastics upon various natural environments. Hofman said that it is "a photo I wish didn't exist" but in my view it speaks loudly about the horror of plastic pollution. The past few months have seen the western world waking up to our plastic carelessness. Perhaps a shocking picture like this will help to turn that growing awareness into positive remedial action. The mad plastic thing has gone on for far too long. It's time for change.
