Oxygen – we all need it, we can't live without it. It's integral to life on this planet. And it's probable that, as you watch this film, you will be breathing in an oxygen atom that was also breathed by Genghis Khan – or by the first ever apes to stand upright on the plains of Africa. The oxygen that we breathe is made from two oxygen atoms joined together – O2. They were first joined more than 3 billion years ago by the earliest blue-green algae to evolve. The oxygen molecule first came from bacteria and was present in the fires that destroyed the dinosaurs and the chemical reactions in all human cells, and as ozone they protect the earth from radiation. Since then, both together and apart, they've had the most extraordinary adventures. Each of the two atoms in an oxygen molecule is virtually indestructible – so they have been first-hand players in some of the most dramatic events in the whole of Earth's history. It's often said that we are breathing the same oxygen that the cavemen did. The life of a single molecule of oxygen is traced on it's astonishing journey spanning millions of years, from its creation, into photosynthesis, through the age of the dinosaurs, early man, and on into today.

From mountain zebras to shy and secretive caracals, Karoo National Park showcases a diversity of creatures who have adapted to demanding environmental conditions. Scale the varying altitudes of this nature reserve's vast landscape.
At the very northern edge of North America is Ellesmere Island, where the unforgiving Arctic winds tear through the tundra, dipping temperatures to 40 below zero. Running through this shifting sea of snow and ice is one of the most hardened predators on the planet, the White Wolf. But as the spring melt approaches, these roaming hunters must adapt to being tethered parents as new additions to the pack have just been born. With their herds of prey continuing to move, we witness a desperate race to keep up and bring back a kill to the hungry mothers and cubs. Traveling farther and farther away from their den each day puts these hunters and their children at risk in this fight for survival.
