BBC One today announces that Sir David Attenborough is to present A Perfect Planet, a brand new five-part natural history super-landmark from Silverback Films.David Attenborough said: "Oceans, sunlight, weather and volcanoes - together these powerful yet fragile forces allow life to flourish in astonishing diversity. They make Earth truly unique - a perfect planet. Our planet is one in a billion, a world teeming with life. But now, a new dominant force is changing the face of Earth: humans. To preserve our perfect planet we must ensure we become a force for good."Charlotte Moore, Director of Content, says: "BBC One continues to lead the way in natural history programming, and I’m thrilled that Sir David Attenborough will be our trusted guide to A Perfect Planet. It will be a breathtaking series celebrating the intricate systems that allow our planet to thrive, bringing together a unique perspective with groundbreaking camera technology."Nancy Daniels, Chief Brand Officer, Discovery, says: "We at Discovery are proud to be a part of A Perfect Planet. With Sir David Attenborough leading the journey, audiences will be in awe of our world and the perfect conditions that created it, and will be reminded what we need to do to preserve it."Planet Earth is perfect. It orbits at the perfect distance from the sun; it tilts at just the right angle and has a decent sized moon to hold it in place. On top of that, the day-to-day workings of the planet naturally serve to nurture animals and plants. For instance, a global weather system circulates and distributes fresh water to all corners, and a cycle of marine currents delivers nutrients to even the deepest reaches of the ocean. As a result, there is literally no corner of our planet where life can’t be found.A Perfect Planet - in a unique fusion of blue chip natural history and earth sciences - explains how the living planet operates. This five-part series will show how the forces of nature - weather, ocean currents, solar energy and volcanoes - drive, shape and support Earth’s great diversity of life. In doing so, it will reveal how animals are perfectly adapted to whatever the environment throws at them.From the white wolves of Ellesemere Island to bears in Kamchatka, vampire finches of the Galapagos to golden snub-nosed monkeys of China, the series will combine a global view of the planet from space with intimate animal stories from the most spectacular habitats. From the Indian Monsoon to Hawaiian volcanoes, tidal islands of the Bahamas to the extremes of the Arctic winter, A Perfect Planet will take the audience on a stunning visual journey that will change the way we see our home.The final episode in the series looks at the dramatic impact of the world’s newest global force of nature - humans.A Perfect Planet, a 5x60’ for BBC One, is a Silverback Films Production for BBC and Discovery, co-produced with Tencent Penguin Pictures, ZDF, China Media Group CCTV9, France Televisions and The Open University.The Executive Producer is Alastair Fothergill, and the Series Producer is Huw Cordey.
