Can Tech Save the World?

As the world leaders meet to talk about climate change Click looks at how technology can help us become more sustainable. We start in the Netherlands meeting a couple who have made a polar expedition vehicle from discarded plastic. We follow them as they start a 40 day expedition across Antarctica. Next we travel to Norway to look at a bot that is cleaning the seabed and educating the public about what lies beneath the surface. And in the US we meet a start up that thinks it's found a cheap way to turn used plastic back to its raw form.
