When David Attenborough speaks, we listen. And he knows it.

Speaking at the start of the World Economic Forum (WEF) in Davos, Switzerland, the 92-year-old naturalist and broadcaster addressed the growing issue of climate change.

After warning the crowd that human activity has taken the world into a threatening new era, he said: “We need to move beyond guilt or blame, and get on with the practical tasks at hand.”

Attenborough knows that climate change can be reversed through education. Education in the form of his documentaries. And we couldn’t agree more – if there is anything we’ve learned it’s that the BBC’s Blue Planet documentary made us address our single-use plastic consumption like never before.

“In 1999, whilst making the Blue Planet series about marine life, we filmed coral-bleaching, but I still didn’t appreciate the magnitude of the damage that had already started,” Attenborough said, referencing the highly acclaimed BBC documentary.

“Now however we have evidence, knowledge and the ability to share it on a scale unimaginable even just a few years ago.

“Movements and ideas can spread at astonishing speed.”

Now, Attenborough is trying to extend his reach through Netflix’s mass subscription service.

“The audience for that first series, 60 years ago, was restricted to a few million viewers in southern England,” he said.

“My next series - Our Planet - which is about to be launched, will go instantly to hundreds of millions of people in almost every country on Earth via Netflix.

“And the evidence supporting the series will be free to view by everyone with an internet connection via WWF.”

Due to air on 5 April 2019, Attenborough will narrate the natural history documentary.

“Our Planet will take viewers on a spectacular journey of discovery showcasing the beauty and fragility of our natural world,” Attenborough said in November. “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. We need the world to pay attention.”

The series, which has been filmed across 50 countries over four years, will take us to places all over the planet – like the Arctic wilderness and vast landscapes of Africa – to explore the world’s most precious species.

“Our Planet will showcase the wonders of our world at the critical time when we need global action to protect it,” Attenborough said.

Our Planet will air on Netflix on 5 April 2019.
