Sir David Attenborough will present \'A Perfect Planet\' later this year.
The veteran broadcaster and naturalist - who has fronted the likes of \'Blue Planet\', \'Planet Earth\' and \'Dynasties\' over the years - will be back on BBC One with a new five-part natural history programme.
He said in a statement: "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."
The series - which combines natural history with earth sciences - will look at how forces of nature drive, shape and support the planet\'s diversity of life.
Charlotte Moore, Director of Content, added: "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 breath-taking series celebrating the intricate systems that allow our planet to thrive, bringing together a unique perspective with groundbreaking camera technology."
And Nancy Daniels, Discovery\'s chief brand officer, commented: "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."
\'A Perfect Planet\' will air on both BBC One and Discovery later this year.
