Today Earth is a human world, home to eight billion people and counting. Humans now have a greater effect in shaping Earth’s surface than many natural processes. In this episode, Chris Packham explores how dramatic twists in Earth’s story enabled humans to go from being part of nature to controlling it, and what we can learn from this epic tale before it’s too late. The story begins 66 million years ago with the catastrophic impact of the asteroid that wiped out the (Non-avian) dinosaurs. From the ashes of the desolation that followed, a new animal family rose to power. This was adaptable and inventive enough to emerge out of the harsh new world – the mammals. It began with a distant ancestor that shared many traits of the much maligned, but evolutionarily brilliant, rat. Due to a series of extreme geological and climatic events, mammals evolved into early primates feasting in the newly formed tropical rainforests, and then to early humans travelling vast distances between forests in places like East Africa’s Rift Valley. Earth’s story is a saga spanning 4.5 billion years, but it’s only in the last 11,000 years - with the rise of farming - that our species has started to dramatically impact our planet and its ecosystems. The human chapter of Earth’s story might end in disaster, but Chris is keen to argue for a different ending, where all of humanity’s achievements to date “…were just our dress rehearsals, because in the very near future our species will need to reach the zenith of its achievements and… all humanity will have to learn to put our Earth first.”

In the frozen wilderness of Antarctica, where oceans ice over and just staying alive is an achievement, one creature has perfected the art of survival - the emperor penguin. Eons of evolution have built an animal superbly adapted to the howling gales and sub-zero temperatures, but the emperor may have finally met its match. Parts of Antarctica are warming, giving birth to huge icebergs, and the consequences could be catastrophic for this majestic animal. In a place where all life is touched by the ice, it is a dramatic shift. Explore this region from its inhabitant's perspective, using state-of-the-art technology. By better understanding these amazing animals, researchers can help prepare for their future, as the balance of life in the Antarctic continues to change.

It is high summer in the Polar Regions, and the sun never sets. Vast hordes of summer visitors cram a lifetime of drama into one long, magical day; they must feed, fight and rear their young in this brief window of plenty. Summer is a tough time for the polar bear family, as their ice world melts away and the cubs take their first swimming lesson. Some bears save energy by dozing on icy sun beds, while others go egg-collecting in an Arctic tern colony, braving bombardment by sharp beaks. There are even bigger battles on the tundra; a herd of musk oxen gallop to the rescue as a calf is caught in a life and death struggle with a pair of Arctic wolves. But summer also brings surprises, as a huge colony of 400,000 king penguins cope with an unlikely problem - heat. The adults go surfing, while the woolly-coated chicks take a cooling mud bath. Nearby, a bull fur seal is prepared to fight to the death with a rival. Fur flies as the little pups struggle desperately to keep out of the way of the duelling giants. Further south, a minke whale is hunted amongst the ice floes by a family of killer whales. The dramatic chase lasts over 2 hours and has never been filmed before. The killers harry the minke whale, taking it in turns to wear it down. Eventually it succumbs to the relentless battering. Finally, comical adelie penguins waddle back to their half a million strong colony like clockwork toys. The fluffy chicks need constant feeding and protection as piratical skuas patrol the skies. When an unguarded chick is snatched, a dramatic "dogfight" ensues.

Patrick follows the grizzly bears that are taking a risk with the weather by leaving their winter dens early. Hungry wolves are struggling to bring down their elk prey in the unusually shallow snow. And for great grey owls, it is the iciness of the snow that is hampering their hunts. Yellowstone's winter is always one of the most brutal on the planet. But 2016 saw weather records broken, and the wildlife was forced to adapt to survive. Kate Humble gets to grips with the science behind this remarkable season, from understanding the importance of the snowpack's structure as the melt begins to uncovering why Yellowstone's unique geology poses problems for some grazer's teeth.
