It was regarded as a responsibility of the BBC to provide programs which have a broad spectrum of interest, and if there was a hole in that spectrum, then the BBC would fill it.

If you watch animals objectively for any length of time, you're driven to the conclusion that their main aim in life is to pass on their genes to the next generation.

Nature isn't positive in that way. It doesn't aim itself at you. It's not being unkind to you.

How could I look my grandchildren in the eye and say I knew what was happening to the world and did nothing.

Apart from anything else, I am designed by evolution, like we all are: if we see a little thing like that, big eyes, tiny nose, we go 'aaah'. That's what evolution does. We are programmed to do that. So to find babies the most amazing, isn't surprising, I don't think.

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

Crying wolf is a real danger.
