I'm against this huge globalisation on the basis of economic advantage.
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.
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.
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.
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.
I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.
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.
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.
As far as I'm concerned, if there is a supreme being then He chose organic evolution as a way of bringing into existence the natural world... which doesn't seem to me to be necessarily blasphemous at all.
The more you go on, the less you need people standing between you and the animal and the camera waving their arms about.
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.
I am an ardent recycler. I would like to think that it works. I don't know whether it does or not.
I don't approve of sunbathing, and it's bad for you.
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.
You know, it is a terrible thing to appear on television, because people think that you actually know what you're talking about.
You have to steer a course between not appalling people, but at the same time not misleading them.
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.
You can cry about death and very properly so, your own as well as anybody else's. But it's inevitable, so you'd better grapple with it and cope and be aware that not only is it inevitable, but it has always been inevitable, if you see what I mean.
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.
Steve Irwin did wonderful conservation work but I was uncomfortable about some of his stunts. Even if animals aren't aware that you are not treating them with respect, the viewers are.
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.
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.
There are some four million different kinds of animals and plants in the world. Four million different solutions to the problems of staying alive.
I'm not a propagandist, I'm not a polemicist; my primary interest is just looking at and trying to understand how animals work.
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.
People are not going to care about animal conservation unless they think that animals are worthwhile.
The only way to save a rhinoceros is to save the environment in which it lives, because there's a mutual dependency between it and millions of other species of both animals and plants.
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.
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.
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.
People must feel that the natural world is important and valuable and beautiful and wonderful and an amazement and a pleasure.
I often get letters, quite frequently, from people who say how they like the programmes a lot, but I never give credit to the almighty power that created nature.
Nature isn't positive in that way. It doesn't aim itself at you. It's not being unkind to you.
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.
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.
The question is, are we happy to suppose that our grandchildren may never be able to see an elephant except in a picture book?
We are not overpopulated in an absolute sense; we've got the technology for 10 billion, probably 15 billion people, to live on this planet and live good lives. What we haven't done is developed our technology.
