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.

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

I'm not over-fond of animals. I am merely astounded by them.

London has fine museums, the British Library is one of the greatest library institutions in the world... It's got everything you want, really.

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

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

We can now destroy or we can cherish-the choice is ours.
