BBC Earth's new nature series explores earth's seven continents

BBC Earth has released a four-minute trailer for their upcoming nature series which explores each of the planet's seven continents to the soothing narration of Sir David Attenborough.

In keeping with previous nature series produced by the BBC, "Seven Worlds: One Planet" promises stunning footage of the natural world, from a lizard captured in slow-motion leaping into the air to catch a fly in its mouth, to images of a large bird sailing through a rainbow, cascading waterfalls and unearthly landscapes. 

"This is the story of those seven worlds," Attenborough says in the promo video. 

"We will see how life developed on each continent and so gave rise to the extraordinary and wonderful diversity we know today. And we will see why this precious diversity is being lost." 

Images for the trailer are set to the soundtrack of a song performed by Australian singer Sia, who co-wrote the piece "Out There" with Hans Zimmer. 

"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," reads the synopsis.  

"From the colorful 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." 

No release date has yet been shared.
