He makes the admission in upcoming documentary Ocean

Fans of Sir David Attenborough have shared their sadness following his statement concerning his longevity in his new Disney+ show Ocean.

The beloved broadcaster, who joined the BBC full time in 1952, has been at the forefront of nature documentary-making for the entirety of most viewers’ lives.

However, in the upcoming Ocean – released on May 8 to coincide with his 99th birthday – Sir David makes a sobering admission about mortality as he looks at how important aquatic life is to sustaining our planet.

‘Final time on location’

That’s because, according to The Sun, Sir David mentions he is “nearing the end of his life”.

The trailer for Ocean shows Sir David speaking by the shore as a blustery wind surrounds him. It is believed the feature-length doc may be the final time he goes on a location shoot for a TV show.

A telly insider is said to have told the tabloid: “They’re two major moments. But despite being associated with the BBC for most of his working life, they both feature in the documentary which is set to drop on Disney+.”

What does Sir David Attenborough say?

At one point, Sir David is reported to tell viewers: “When I first saw the sea as a young boy, it was thought of as a vast wilderness to be tamed and mastered for the benefit of humanity. Now, as I approach the end of my life, we know the opposite is true.

“After living for nearly a hundred years on this planet, I now understand that the most important place on Earth is not on land, but at sea.”

But despite reflecting on how humans are “almost out of time”, Sir David maintains creating protected marine reserves where fishing is banned could allow the ocean to recover.

Sir David’s fans react

Reacting to the online stories of David – who turns 99 on May 8 – and his recent statement, fans were quick to share their heartbreak.

One person said: “Sir David Attenborough saying he’s nearing the end of his life is actually not what I needed to hear. I need him to live forever.”

Someone else added: “We must force this man not to die. It must not be allowed. Do something!!!”

A third chimed in: “I don’t think I’m ready for this. Man voice is like an inside monologue in my head whenever I’m out for a jog or taking a stroll.”

Another fan said: “When he goes I dread to see the state of our planet.”

Is Sir David Attenborough still alive and how old is he?

Sir David Attenborough is still very much alive. He was born in May 1926, which means he is currently 98. But within a matter of weeks will turn 99.

Relatives have also enjoyed long lives – but not as long as Sir David. His father Frederick Attenborough, an academic, was 85 when he passed away.

Meanwhile his elder brother and film legend Sir Richard Attenborough was 90 when he died. And their younger brother John Attenborough, a motor industry executive, made it to 84.

Sir David’s wife Jane, with whom he shares two children, died in 1997. They were married for 47 years.
