Before the BBC, I joined the Navy in order to travel.
An understanding of the natural world and what's in it is a source of not only a great curiosity but great fulfillment.
All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.
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 think a major element of jetlag is psychological. Nobody ever tells me what time it is at home.
Being in touch with the natural world is crucial.
It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.
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'm not in politics.
I've been to Nepal, but I'd like to go to Tibet. It must be a wonderful place to go. I don't think there's anything there, but it would be a nice place to visit.
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.
It is that range of biodiversity that we must care for - the whole thing - rather than just one or two stars.
I'm absolutely strict about it. When I land, I put my watch right, and I don't care what I feel like, I will go to bed at half past eleven. If that means going to bed early or late, that's what I live by. As soon as you get there, live by that time.
Crying wolf is a real danger.
I like animals. I like natural history. The travel bit is not the important bit. The travel bit is what you have to do in order to go and look at animals.
