David Attenborough, 99, Shares Crucial Message in New Film "Ocean"

After nearly 100 years on the planet, I now understand that the most important place on earth is not on land, but at sea, says Sir David Attenborough, who turns 99 years old on Thursday, to BBC.

The biofilm "Ocean with David Attenborough" premiered at the Royal Festival Hall in London on Tuesday. Among the guests were King Charles, Prince William and celebrities such as singer Geri Halliwell-Horner, astronaut Chris Peake and model Cara Delevingne.

The film documents how the state of the world's oceans has changed during Attenborough's lifetime and is now at a crossroads. Among other things, it takes up the damage that bottom trawling causes to the seabed. According to Attenborough, a living example of how fishing can drain life from the oceans.

It's hard to imagine a more wasteful way of catching fish, he comments.
