In the old days... it was a basic, cardinal fact that producers didn't have opinions. When I was producing natural history programmes, I didn't use them as vehicles for my own opinion. They were factual programmes.

I think a major element of jetlag is psychological. Nobody ever tells me what time it is at home.

The climate, the economic situation, rising birth rates; none of these things give me a lot of hope or reason to be optimistic.

Steve Irwin did wonderful conservation work but I was uncomfortable about some of his stunts. Even if animals aren't aware that you are not treating them with respect, the viewers are.

Its about cherishing the woodland at the bottom of your garden or the stream that runs through it. It affects every aspect of life.
