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.

The formation of continents with varied environments allowed for an explosion of biodiversity — and turbo-charged the evolution of mighty dinosaurs.

Never before has a film crew had such unrestricted access to the wonders of Saudi Arabia's seas. Desert Seas narrated by Sir David Attenborough tells the story of how the peninsula of Arabia transformed from an ocean millions of years ago to the desert it is today.

Describes the inhospitable habitats of snow and ice. Mount Rainier in America is an example of such a place: there is no vegetation, therefore no herbivores and thus no carnivores. However, beneath its frosty surface, algae grow and some insects, such as ladybirds visit the slopes. Africa’s mountains are permanently snow-covered, and beneath peaks such as Kilimanjaro and Mount Kenya, there are communities of plants and animals.

Our planet has had a difficult and violent past. The potential for life all begins when Earth collides with another protoplanet, the size of Mars, shortly after the formation of our solar system. The impact nearly destroys our home, but Earth survives. And in the end a new world was created: The moon. Although it causes a lot of trouble on Earth, it is the moon that plays an important role in the story of how life ultimately came to be on our planet.

There's a whole world, and more than one spectrum of sensations that animals are aware of, which surpass humans. There's a kind of "sixth sense" that some animals have, which still defies explanation. Call it extra-sensory perception animal abilities we can't entirely explain.
