Life is not all high emotion. Some of the most interesting things are when its not highly emotional: little details of relationships and body language.

I'm no longer sceptical. I no longer have any doubt at all. I think climate change is the major challenge facing the world.

The more you go on, the less you need people standing between you and the animal and the camera waving their arms about.

Fundamentally not to waste energy. If we were all to reduce our demands for energy, it would make an enormous amount of difference.

The process of making natural history films is to try to prevent the animal knowing you are there, so you get glimpses of a non-human world, and that is a transporting thing.

Natural history is not about producing fables.

I don't know [why we're here]. People sometimes say to me, 'Why don't you admit that the humming bird, the butterfly, the Bird of Paradise are proof of the wonderful things produced by Creation?' And I always say, well, when you say that, you've also got to think of a little boy sitting on a river bank, like here, in West Africa, that's got a little worm, a living organism, in his eye and boring through the eyeball and is slowly turning him blind. The Creator God that you believe in, presumably, also made that little worm. Now I personally find that difficult to accommodate.
