In this final installment to the series, David Attenborough travels to four unique locations about the globe where an abundance of fossilized plant and animal remains have given us a detailed picture of what life could have been like in prehistoric times. Each of the sites experienced its own set of circumstances which enabled it to preserve many perfect specimens for extraction and analysis. Piecing together the collected evidence, paleontologists have been able to determine early animal hierarchies, their diets and their evolutionary paths.

The Belize Barrier Reef is the second-largest coral reef system in the world. Estimated to be nearly 4,000 years old, its waters are home to an immense marine ecosystem. Explore a deep blue wilderness brimming with rare, exotic fish, sea turtles, sharks, and huge green morays.

Discover a land of hauntingly beautiful coasts, magical forests, and volcanic and arctic extremes - and the lynx, orcas, puffins and wolves who call this frozen kingdom home. Chapter 1: Life on the Edge Wild and unpredictable, the Scandinavian coast is a place of haunting beauty and dangerous extremes - a journey from storm-swept islands crowded with seal pups to 3,000ft deep fjords where sea eagles fly and base jumpers parachute from the edge. In the far north, tropical currents and Arctic seas collide, creating riches - billions of herring tracked by orcas and humpback whales - while providing a home to thousands of seabirds, including the feisty puffin. Chapter 2: Heartlands Great forests form the heart of Scandinavia, stretching towards the Arctic and cutting through with a labyrinth of waterways. Incredible creatures like lynxes, wolves, bears and reindeer must survive the ever-changing seasons - from the chilling grip of winter to the warm riches of summer. Here, all life is deeply interconnected through surprising and ancient partnerships, creating a balance that has evolved over millennia. Chapter 3: Ice and Fire Scandinavia's northern extremes have been shaped by ice and fire, but it's the sun that reigns over these frozen kingdoms. Here, musk oxen, polar bears and arctic foxes must endure the long, dark polar night, but in spring, the sun's return ignites a dramatic transformation in the landscape and heralds the return of thousands of migrant visitors. Under the midnight sun, the north bursts into a sleepless rush of life and opportunity, a race against time to raise a family, but for some, it's the summer heat which brings the greatest dangers before the first frost and winter's welcome return.

Not many can intimidate North America's top predator, Tyrannosaurus rex, whose size and bite are a deadly combo, except for a giant winged foe.

Take a trip through the spectacularly diverse terrain of the Waterberg--a South African land so old it was formed before terrestrial life itself. Today, its sprawling grasslands are home to some of the most eclectic wildlife on Earth, all sustained by the region's abundant water supply.

With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases. Extinction is now happening up to 100 times faster than the natural evolutionary rate, but the issue is about more than the loss of individual species. Everything in the natural world is connected in networks that support the whole of life on earth, including us, and we are losing many of the benefits that nature provides to us. The loss of insects is threatening the pollination of crops, while the loss of biodiversity in the soil also threatens plants growth. Plants underpin many of the things that we need, and yet one in four is now threatened with extinction. Last year, a UN report identified the key drivers of biodiversity loss, including overfishing, climate change and pollution. But the single biggest driver of biodiversity loss is the destruction of natural habitats. Seventy-five per cent of Earth's land surface (where not covered by ice) has been changed by humans, much of it for agriculture, and as consumers we may unwittingly be contributing towards the loss of species through what we buy in the supermarket. Our destructive relationship with the natural world isn’t just putting the ecosystems that we rely on at risk. Human activities like the trade in animals and the destruction of habitats drive the emergence of diseases. Disease ecologists believe that if we continue on this pathway, this year’s pandemic will not be a one-off event.
