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.
Everything in the natural world is connected in networks that support the whole of life on earth, 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.
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. 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.

On the coast, two worlds collide. Coasts are the most dynamic and challenging habitats in the ocean - that brings great rewards but also great danger. The extraordinary animals that live here must find ingenious ways to cope with two very different worlds. This episode is a rollercoaster ride of heart-stopping action and epic drama, peopled with characters from the beautiful to the bizarre. We meet fish that live on dry land and puffins that must travel 60 miles or more for a single meal, and witness a life-and-death struggle in a technicolour rock pool. In a secluded cove in the Galapagos, sea lions feast on 60kg tuna. It should be impossible - tuna are usually far too fast for sea lions to catch. But here the sea lions club together to herd their prey inshore. Once trapped in the shallows, these huge fish are easy pickings. As the tide recedes in Brazil, lightfoot crabs leap from rock to rock, desperately avoiding the water - their lives depend on it. Moray eels launch themselves from rock pools, jaw gaping. Then octopuses, too. Both crawl across dry rock to set their ambush. Elsewhere, the ever-changing tides create rock pools. But these temporary worlds are a battleground. Predatory starfish turn a magical garden into the stuff of nightmares.

Experience a wondrous adventure from the dinosaur age with 'Sea Rex Journey to a Prehistoric World'. Join Julie, an imaginative young woman, as she travels from a modern-day aquarium to the Triassic, Jurassic and Cretaceous periods. Explore an amazing underwater universe inhabited by larger-than-life creatures including the powerful Liopleurodon, long-necked Elasmosaurus and gigantic Shonisaurus which were ruling the seas before dinosaurs conquered the earth.
Thanks to state-of-the-art ultra-photorealistic imagery in 3D or 2D, see science come alive in a unique and entertaining manner. Immerse yourself in a lost age, 200 million years back in time, and get ready for a face-to-face encounter with the T-Rex of the seas. Directed by Ronan Chapalain and Pascal Vuong.

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called 'coral bleaching' -a sign of mass coral death- has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.
Chasing Coral taps into the collective will and wisdom of an ad man, a self-proclaimed coral nerd, top-notch camera designers, and renowned marine biologists as they invent the first time-lapse camera to record bleaching events as they happen. Unfortunately, the effort is anything but simple, and the team doggedly battles technical malfunctions and the force of nature in pursuit of their golden fleece: documenting the indisputable and tragic transformation below the waves. With its breathtaking photography, nail-biting suspense, and startling emotion, Chasing Coral is a dramatic revelation that won't have audiences sitting idle for long.

In these extraordinary times, there is one thing that can offer solace to everyone – the wonder of the natural world. In the most extreme of environments, from the hottest deserts to the freezing poles, from the highest mountains to underwater kingdoms, animals overcome adversity to survive and thrive, offering a message of hope to humanity.
To raise our spirits, David Attenborough, Hans Zimmer and Dave unite for a special Natural History event – Planet Earth: A Celebration. The special one-hour programme brings together eight of the most extraordinary sequences from Planet Earth II and Blue Planet II including racer snakes vs iguana, surfing bottlenose dolphins and rare footage of the Himalayan snow leopard.

Jean-Michel Cousteau invites you to embark on a breathtaking underwater voyage to discover the ultimate predator: the shark. Experience an astonishing up-close encounter in 3D with the Lions and Tigers of the Ocean. Come face-to-face with a multitude of shark species, including the Great White, Hammerhead, and Whale Shark. Witness them as they really are: not wicked man-eating creatures, but wild, fascinating and endangered animals that have been in existence a million years before dinosaurs roamed the Earth. Join a team of ocean explorers on a round-the-globe expedition documenting the life of the ultimate predator.
