David Attenborough has promised fans a "spectacular journey of discovery" on his new Netflix show Our Planet, which is set to premiere on the streaming service next April.

Four years in the making, the eight-part series, made in collaboration with the World Wildlife Fund (WWF), will debut on April 5, 2019, with Attenborough narrating the wonders onscreen.

"Today we have become the greatest threat to the health of our home, but there's still time for us to address the challenges we've created, if we act now," said 92-year-old Attenborough at the WWF's State of the Planet Address event in London. "We need the world to pay attention. 

"Our Planet brings together some of the world's best filmmakers and conservationists and I'm delighted to help bring this important story to millions of people worldwide."

Also on board for the new series is Silverback Films. Its director, Alastair Fothergill, created the original Planet Earth and Blue Planet.

"Our Planet is our most ambitious endeavour to date," said Fothergill. "We hope it will inspire and delight hundreds of millions of people across the world so they can understand our planet, and the environmental threat it faces, as never before.

"The crew have ventured to all corners of the globe to capture breathtaking natural history sequences and [were] using the latest filming technology to bring these never-filmed-before moments into people's homes."

David Attenborough was Ryan Tubridy's guest on RTÉ Radio 1 last month. Listen to the interview here.
