The fundamental issue is the moral issue.

I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.

I've been bitten by a python. Not a very big one. I was being silly, saying: 'Oh, it's not poisonous' Then, wallop! But you have fear around animals.

I mean, it is an extraordinary thing that a large proportion of your country and my country, of the citizens, never see a wild creature from dawn 'til dusk, unless it's a pigeon, which isn't really wild, which might come and settle near them.

Cameramen are among the most extraordinarily able and competent people I know. They have to have an insight into natural history that gives them a sixth sense of what the creature is going to do, so they can be ready to follow.

Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.

No one will protect what they don't care about, and no one will care about what they have never experienced.
