Humans have spread across the planet, leaving our mark on the landscapes and ecosystems we rely on. But is there anywhere left that is unchanged by humans? Anywhere we haven’t affected – whatsoever? Presenter Caroline Steel and producer Florian Bohr continue their search for the last places on Earth free from human impact. In this second episode, we dive into our oceans. Deep-sea ecologist Jeff Drazen guides us through the ocean’s mysterious layers. And in a submersible 11,000 metres below the surface - the second deepest point on the planet - we join marine biologist Alan Jamieson as he makes a startling discovery. Could No Man’s Land be hidden in the deep? Presenter: Caroline Steel Producer: Florian Bohr Editor: Martin Smith Production Co-ordinator: Stuart Laws
