Millions of years ago incredible forces ripped apart the Earth's crust creating our seven continents - each with its own distinct climate, its own distinct terrain and its own unique animal life. From the colourful paradise of South America to the scorching heat of Africa, ‘Seven Worlds, One Planet’ showcases the true character of each continent in turn and reveals just how it has shaped all life there. Be surprised by unexpected stories. Marvel at iconic landscapes. And be awestruck by spectacular wildlife. This series is an eye-opening journey around a world you thought you knew.
The snowy shores and icy waters of Antarctica are home to some of the most amazing and unusual wildlife in the world. However, even here, many species face extinction due to rapid climate change and overhunting.

Extraordinary. Dramatic. Beautiful. The series exposes the wonders of British wildlife. It's our home, as you've never seen it before. David Attenborough celebrates Britain's wildlife that is as dramatic and spectacular as any he's seen abroad and reveals why it is globally important for nature.
In this special documentary commissioned by the RSPB, WWF and National Trust and inspired by Wild Isles, we meet passionate people trying to restore nature to the British Isles.

Sir David Attenborough explores the surprisingly vibrant seas that surround the British Isles. The vast watery wilderness around us is over three times the size of our land mass, and yet to many, our oceans remain a mystery. Full of colour and teeming with life, the seas of Britain and Ireland are crucially important to a range of wildlife. This episode goes beneath the waves to uncover the thriving habitats that exist along our 22,000-mile coastline.
In winter, clear evidence of the ocean’s abundance can be seen on a beach in Norfolk. Thousands of grey seals congregate on the shoreline to give birth. Britain and Ireland are home to 40 per cent of the world’s grey seals, and the number being born on our shore rises every year. Once the newly born pups are weaned, the females are ready to breed again, and heavyweight males enter violent, bloody fights to win a stretch of beach, and the females along with it.
Beyond the beach, the vibrant shallows contain several important habitats. Rich beds of seagrass are nurseries for a range of animals, while also acting as very important carbon storage areas. They are also home to one of the strangest fish in our waters, the seahorse. We follow a male and female as they perform a balletic mating dance in the water, delicately entwining their tails. The stakes are high, as these animals mate for life.
In a touching piece to camera, Sir David bids a fledging Manx shearwater chick farewell as it embarks on a 6,000-mile journey across the oceans to South America. There is no better example of how important the British Isles and its abundant seas are to the survival of wildlife worldwide.
