Message in the Waves is a film made by the BBC Natural History Unit that set out to look at some of the environmental challenges facing Hawaii.
And what did they find? Well, plastic of course.
You can read about the making of the documentary, watch a trailer, and download a copy of it on the Message in the Waves website.
One of the team behind the documentary, Rebecca Hosking, was so appalled by what she saw during filming that it inspired her to launch a campaign in her home town of Modbury to ban the plastic bag. In May 2007 they became the first town in the UK to achieve this, and their actions have inspired many others to follow suit.
What about your town? Can you inspire them to do the same? There is all sorts of information out there to help, from Rebecca's book, Ban the Plastic Bag, to advice from the Marine Conservation Society, and their guide on being plastic free.
