I was born into a world of just under two billion people today there are nearly seven billion of us. Whenever I hear those numbers I can honestly say I find it incredible, triple the number of human beings in what seems like the blink of an eye and the world transformed utterly.

I've spent much of the last 50 years seeking wilderness filming animals in their natural habitat and, to some extent, avoiding humans. But, over the years, true wilderness has become harder to find.
