I am 94. I've had an extraordinary life. It's only now that I appreciate how extraordinary.
As a young man, I felt I was out in the wild, experiencing the entire natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable daily - the loss of our planet's wild places and its biodiversity.
I have been witness to this decline. A Life on Our Planet is my witness statement and my vision for the future. It is the story of how we made this, our most significant mistake - and how, if we act now, we can put it right.
We have one final chance to create our perfect home and restore the wonderful world we inherited.
All we need is the will to do so.
