Sir David says the state of the ocean has almost made him lose hope for the future of life on the planet. What has kept him from despair is what he calls the “most remarkable discovery of all” – that the ocean can “recover faster than we had ever imagined”.
Sir David says the story of the world’s whales has been a source of huge optimism for him.
It is estimated that 2.9 million whales were killed by the whaling industry in the 20th Century alone. Scientists have said it is the largest cull of any animal in history when measured in terms of total biomass. It pushed almost all whale species to the edge of extinction.
Just one per cent of Blue Whales were left, recalls Sir David: “I remember thinking that was it. There was no coming back, we had lost the great whales.”
But in 1986 lawmakers bowed to public pressure and banned commercial whaling worldwide. The whale population has rapidly recovered since then.
One of the film’s directors, Keith Scholey, has worked with Sir David for 44 years. “When I first met David, I was in shorts,” he jokes. That was in 1981, two years after Sir David had resigned as the BBC’s director of programmes – one of the most senior jobs at the Corporation. “He’d done one career, and he was off on his next.”
Despite now nearing his 99th birthday Sir David is still remarkably energetic, says Scholey. “Every time you work with David, you learn something new,” he says. “It’s really good fun. But also, David keeps you on your mettle, because he is so on his mettle and so, you know, it’s always a very creative process.”
