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.
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.
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.
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.
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.
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.
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.
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.
People are not going to care about animal conservation unless they think that animals are worthwhile.
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.
We keep putting on programmes about famine in Ethiopia; that's what's happening. Too many people there. They can't support themselves - and it's not an inhuman thing to say. It's the case. Until humanity manages to sort itself out and get a coordinated view about the planet it's going to get worse and worse.
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 can mention many moments that were unforgettable and revelatory. But the most single revelatory three minutes was the first time I put on scuba gear and dived on a coral reef. It's just the unbelievable fact that you can move in three dimensions.
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.
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.
There are some four million different kinds of animals and plants in the world. Four million different solutions to the problems of staying alive.
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.
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.
The climate, the economic situation, rising birth rates; none of these things give me a lot of hope or reason to be optimistic.
You can only get really unpopular decisions through if the electorate is convinced of the value of the environment. That's what natural history programmes should be for.
