David Attenborough narrates the intimate story of a leopard mother and her two cubs. This very special family must survive in the wilds of Botswana alongside some less-than-friendly neighbours: lions, wild dogs and hyenas. The competition for food is tough, and if they are going to make it they must learn a new skill - they must learn to fish. This is an epic family drama. With them every step of the way is local cameraman Brad Bestelink. Brad's 18-month journey following the lives of these secretive big cats offers a rare glimpse into an otherwise hidden world.

In Bhutan, Palin finds himself back in the land of yaks for a last look at the high Himalaya. Trekking to Chomolhari base camp he meets a nomad with a penchant for yak songs before heading down to Paro to witness the Buddhist festival or Tsechu. In a bar in Thimphu, he discusses reincarnation and the pursuit of happiness with Benji and Khendum, two of the king's cousins, and en route to Bangladesh is taken by Benji to see the rare black-neck cranes. On his journey south through Bangladesh, Michael visits the ship-breaking beaches of Chittagong and grid-locked Dhaka. He meets a man who made a fortune in Birmingham in the poultry business, and a woman who lends money only to women. On a 1920s paddle steamer he is serenaded with the words of Bengal's Shakespeare, and he completes his epic Himalayan journey aboard a fishing boat that carries him out into the Bay of Bengal and a westering sun.

Immense shoals of fish throng our shallow seas. Small fish, in turn, sustain bigger ones. The rich coastal seas are the fishing grounds of our planet and can provide an abundance of food for wildlife and humanity. The seas fringing land make up less than a tenth of the world's oceans but 90 percent of marine creatures live in coastal waters, from fearsome sharks to lowly urchins. Protecting these habitats is a battle humanity must win.

In the last 50 years, we have doubled the amount of fish we consume. Globally, billions of people rely on seafood as their primary source of protein. But the oceans can't keep up with so much demand. Around the world, fish stocks have plummeted and fisheries are crashing. People lost out. There was an industry just completely ravaged.
As the global fish supply dwindles, the industry faces a crisis on all sides - including crooked moguls, dubious imports and divisive regulations.

A bird's-eye view of some of the world's greatest natural spectacles. Amazing sights from five continents are revealed in a whole new light. Using cutting edge new filming techniques to show everything in exquisite detail, viewers have a uniquely privileged perspective. The first episode takes flight across North America, as a flock of millions of snow geese discover what it is like to be on the hit list of America's national bird: the bald eagle. In California, pelicans reveal devil rays that perform astonishing somersaults and find bizarre grunion fish that wriggle ashore to spawn. In Alaska, bald eagles swoop among brown bears fishing for salmon. And on the Great Plains, cowbirds duck and dive under the feet of fighting bison.

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.
