Sir David Attenborough looks at animal behaviour from all continents

Seven Worlds, One Planet begins tonight on the BBC.

“I’m thrilled that we’re about to share this incredible series with the world, which has been four years in the making by more than 1500 dedicated people, on every continent. Seven Worlds, One Planet celebrates biodiversity and the variety of life on our planet whilst also shining a spotlight on its challenges.” – Sir David Attenborough

Millions of years ago incredible forces ripped apart the Earth’s crust, creating seven extraordinary continents. Seven Worlds, One Planet presented by Sir David Attenborough, will reveal how each distinct continent has shaped the unique animal life found there.

This series will feature remarkable new animal behaviour from all the continents, including the baking plains of Africa and the frozen waters off Antarctica. The series will celebrate the diversity of life on each of these continents, but also feature the many challenges faced by animals in a modern world dominated by humanity.

Episode one takes us to Antarctica – the coldest, windiest, most hostile continent. Only the toughest can survive here. From Weddell seals that grind back the ice with their teeth, to colourful starfish carpeting the seabed beneath the ice; huge colonies of king penguins crowd any ice-free land, and four-tonne elephant seals fight for territory on the beach.

Life comes here because the ocean that surrounds the continent is incredibly rich. Thousands of penguins, seals, albatross, and over a hundred great whales feast on krill baitballs. However, the ocean here is warming – and with that comes an uncertain future.

Seven Worlds, One Planet airs this evening on BBC One from 6.35pm

“Seven Worlds, One Planet embodies the qualities that have become synonymous with the work of our Natural History Unit in Bristol. The team there are true pioneers – they have an insatiable curiosity to discover new things. And that sense of adventure is why we’ve already committed to a pipeline of natural history landmarks. Since Planet Earth II we’ve been doing one a year – and we’ll continue to do that running up to 2023. We’ve never had that scale of ambition before and no other broadcaster in the world comes close to that kind of commitment to the natural world.” – BBC Director General Tony Hall
