Documentary on the Shackleton Antartic expedition. A retelling of Sir Ernest Shackleton's ill-fated expedition to Antarctica in and the crew of his vessel 'The Endurance', which was trapped in the ice floes and frigid open ocean of the Antarctic in 1914. Shackleton decided, with many of his crew injured and weak from exposure and starvation, to take a team of his fittest men and attempt to find help. Setting out in appalling conditions with hopelessly inadequate equipment, they endured all weather and terrain and finally reached safety. Persuading a local team of his confidence that the abandoned team would still be alive, he set out again to find them. After almost 2 years trapped on the ice, all members of the crew were finally rescued.

Over eight million tonnes of plastic enters the ocean each year, killing sea life. Now new evidence says it's entering our food chain with unknown health effects.

99% of the plastic that should be floating in the oceans is missing. Even accounting for the plastic that washes up on beaches or is trapped in arctic ice, millions of tonnes has simply disappeared. As most plastic never deteriorates, it simply breaks down into smaller and smaller particles that are invisible to the human eye, what happens to this missing ocean plastic is a mystery. In this investigation, scientists embark in search of the micro-plastics. Small, mostly invisible, toxic, they are home to the new ecosystem: the plastisphere. But where are they? Ingested by organisms? Buried under the ocean floor? Degraded by bacteria? And what is the impact of them entering the food chain?
