I'd like to see the giant squid. Nobody has ever seen one. I could tell you people who have spent thousands and thousands of pounds trying to see giant squid. I mean, we know they exist because we have seen dead ones. But I have never seen a living one. Nor has anybody else.

Dealing with global warming doesn't mean we have all got to suddenly stop breathing. Dealing with global warming means that we have to stop waste, and if you travel for no reason whatsoever, that is a waste.

To suggest that God specifically created a worm to torture small African children is blasphemy as far as I can see. The Archbishop of Canterbury doesn't believe that.

I'm not in politics.

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.

Being in touch with the natural world is crucial.

It is vital that there is a narrator figure whom people believe. That's why I never do commercials. If I started saying that margarine was the same as motherhood, people would think I was a liar.

Crying wolf is a real danger.

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.

It is that range of biodiversity that we must care for - the whole thing - rather than just one or two stars.

People talk about doom-laden scenarios happening in the future: they are happening in Africa now. You can see it perfectly clearly. Periodic famines are due to too many people living on land that can't sustain them.

Everyone likes birds. What wild creature is more accessible to our eyes and ears, as close to us and everyone in the world, as universal as a bird?

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.

I don't approve of sunbathing, and it's bad for you.

It's a moral question about whether we have the right to exterminate species.

I think we're lucky to be living when we are, because things are going to get worse.

I don't like rats, but there's not much else I don't like. The problem with rats is they have no fear of human beings, they're loaded with foul diseases, they would run the place given half the chance, and I've had them leap out of a lavatory while I've been sitting on it.

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.

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

I'm against this huge globalisation on the basis of economic advantage.

It's coming home to roost over the next 50 years or so. It's not just climate change; it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.

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.

I had a huge advantage when I started 50 years ago - my job was secure. I didn't have to promote myself. These days there's far more pressure to make a mark, so the temptation is to make adventure television or personality shows. I hope the more didactic approach won't be lost.

I don't run a car, have never run a car. I could say that this is because I have this extremely tender environmentalist conscience, but the fact is I hate driving.

I'm not an animal lover if that means you think things are nice if you can pat them, but I am intoxicated by animals.

Birds are the most popular group in the animal kingdom. We feed them and tame them and think we know them. And yet they inhabit a world which is really rather mysterious.

There is no question that climate change is happening; the only arguable point is what part humans are playing in it.

Many individuals are doing what they can. But real success can only come if there is a change in our societies and in our economics and in our politics.

There are some four million different kinds of animals and plants in the world. Four million different solutions to the problems of staying alive.

The whole of science, and one is tempted to think the whole of the life of any thinking man, is trying to come to terms with the relationship between yourself and the natural world. Why are you here, and how do you fit in, and what's it all about.

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.

Getting to places like Bangkok or Singapore was a hell of a sweat. But when you got there it was the back of beyond. It was just a series of small tin sheds.

Well, I'm having a good time. Which makes me feel guilty too. How very English.

It's extraordinary how self-obsessed human beings are. The things that people always go on about is, 'tell us about us', 'tell us about the first human being'. We are so self-obsessed with our own history. There is so much more out there than what connects to us.

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.

Television of course actually started in Britain in 1936, and it was a monopoly, and there was only one broadcaster and it operated on a license which is not the same as a government grant.

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.

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

You know, it is a terrible thing to appear on television, because people think that you actually know what you're talking about.

The question is, are we happy to suppose that our grandchildren may never be able to see an elephant except in a picture book?

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

What I am interested in with birds, just as I am with spiders or monkeys, is what they do and why they do it.

Natural history is not about producing fables.

I believe the Abominable Snowman may be real. I think there may be something in that.

If I can make programmes when I'm 95, that would be fine. But I would think I'll have had enough by then.

I'm swanning round the world looking at the most fabulously interesting things. Such good fortune.

I would be absolutely astounded if population growth and industrialisation and all the stuff we are pumping into the atmosphere hadn't changed the climatic balance. Of course it has. There is no valid argument for denial.

We really need to kick the carbon habit and stop making our energy from burning things. Climate change is also really important. You can wreck one rainforest then move, drain one area of resources and move onto another, but climate change is global.

If my grandchildren were to look at me and say, 'You were aware species were disappearing and you did nothing, you said nothing', that I think is culpable. I don't know how much more they expect me to be doing, I'd better ask them.
