And it seems the much-loved naturalist would indeed be up for the challenge, should the occasion arise.
“I have no idea as to whether I could convince him, but it would be cowardly not to take up the challenge, would it not?” reasons the 92-year-old when we meet.
“But I would think carefully about what I actually said.
“There’s so many bits of evidence I would use, [from] the increase in the human population to where we’re all going to get fed. How do you make the arithmetic work?
“And what are you going to do if the oceans are beginning to be depleted, instead of being the great resource for food that we think we’re going to have to rely on?” he asks.
“But, I mean, what you say to him in the face of what is visibly happening with the climate of the United States of America...” he muses. “It’s perfectly clear, [but] there are none so blind as those who will not see.”
Attenborough is talking ahead of the launch of Our Planet – his latest narration project and the follow-up to Planet Earth.
With Alastair Fothergill and Keith Scholey of Silverback Films at the helm once again, the eight-part documentary series will combine stunning photography and technology with an unprecedented look at some of the world’s rarest animals and most precious natural habitats.
Using the latest in 4K camera technology, the show – in partnership with the World Wide Fund for Nature (WWF) – will transport viewers to a total of 50 countries, from the remote ice caps of the Arctic wilderness and mysterious deep ocean to the desert landscapes of Africa and diverse jungles of South America.
It also marks the first time BBC veteran Attenborough has directly collaborated with Netflix.
“The BBC, powerful though it is and pervasive though it is, can’t reach 200 million people overnight, simultaneously,” he says of his decision to join forces with the streaming service, which now has in excess of 139 million subscribers spanning 190 countries.
“And nor can it continue showing those programmes, continuously, for the next six months – or forever.”
“Also the Netflix audience skews to the under 30s,” Fothergill says. “That’s the heart of the audience and those are the people, more than anyone, that care about the state of the planet.”
“We’ve all worked for the BBC and we’ve all worked together, all three of us, over the years,” Attenborough adds, gesturing to Fothergill and Scholey, with whom he worked on Frozen Planet and Blue Planet.
“I’m already on Netflix – the BBC shows which Netflix has taken,” adds the broadcaster, whose professional career has spanned six decades.
“And for this particular project, and this particular ambition, to be able to reach the vast majority with television sets in the world, overnight, is very important.”
He continues: “The message we have is urgent. It’s not, ‘OK, well, we’ll leave it. And in a few months’ time, maybe we’ll sell it here or move it there’.
“We can put things right tomorrow if we had the will,” insists Attenborough. “We could impose marine sanctuaries tomorrow and solve the problem of feeding the world for the next few decades – but that’s easier said than done.
“This project is about a continuing message which we hope, and WWF hopes, will last all the way to Beijing 2020,” he explains.
“Beijing is the next big UN meeting about biodiversity. So this series, the website around it, and the continuing communication is about moving the dial globally towards [that event].”
But Attenborough isn’t decamping to Netflix entirely.
It was recently announced that he will work on One Planet: Seven Worlds – the first of five major wildlife series that will debut on the BBC in the next three years.
“I am involved with that one, but whether I will be involved [with the others]...’ he tails off, before adding: “When you’re 92, you’re given a contract for three months ahead!”
Would he take them on, given the opportunity?
“With a big advance, if you don’t mind. While I’m still alive,” he quips. “I couldn’t guarantee it because I don’t know what the contracts are, but I am a BBC man.
“I joined the BBC in 1952, you know, and I have worked for them constantly. I went to Sky when Sky was actually doing 3D, which the BBC wasn’t doing; I am working with Netflix, when we’re having a world release, which the BBC can’t do; but the BBC has been my life,” he concludes, having most recently teamed up with the broadcaster for Dynasties.
“And I actually think the BBC is one of the things that this country ought to be extremely proud of – I am very proud to be part of it.”
