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.

Professor Richard Fortey journeys high in the Rocky Mountains to explore a 520-million-year-old fossilised seabed containing bizarre and experimental lifeforms that have revolutionised our understanding about the beginnings of complex life. Among the amazing finds he uncovers are marine creatures with five eyes and a proboscis; filter-feeders shaped like tulips; worm-like scavengers covered in spikes but with no identifiable head or anus; and a metre-long predator resembling a giant shrimp.

The most extreme and wild parts of New Zealand are in the South Island, which lie towards Antarctica, in the path of the tempestuous 'roaring forties'. This is home to some of the most rapidly rising mountains in the world, the Southern Alps. From hyper-intelligent parrots to sinister snails with teeth and magical constellations of glow-worms, this is the story of New Zealand's wildest places and its most resilient pioneers, all of whom must embrace radical solutions to survive.
