David Attenborough Quotes

Tyrannosaurus rex, an animal to spark the imagination for all of us. What kind of an animal was it? What did it look like? How did it live? Now, scientific research has answered such questions, and not just about T. rex, but the other species that lived alongside it. And the latest imaging technology enables us to bring them all… to life.

At a time when it's possible for thirty people to stand on the top of Everest in one day, Antarctica still remains a remote, lonely and desolate continent. A place where it's possible to see the splendours and immensities of the natural world at its most dramatic and, what's more, witness them almost exactly as they were, long, long before human beings ever arrived on the surface of this planet. Long may it remain so.

To suggest that God specifically created a worm to torture small African children is blasphemy as far as I can see.

[African Rift Valley soda lakes]. Steaming-hot water comes from volcanic springs and is so loaded with soda that around the margins of the lake it solidifies into white curds. Yet flamingos come here in thousands. [...] The fact that so few creatures can tolerate these conditions means that any animal that can, has the place to itself and so can proliferate in vast numbers.

If you understand about the natural world, we’re a part of the system and you can’t feed lions grass. But because we have the intelligence to choose… But we haven’t got the gut to allow us to be totally vegetarian for a start. You can tell by the shape of our guts and the shape of our teeth that we evolved to be omnivores. We aren't carnivores like lions but neither are we elephants.

Today we're living in an era in which the biggest threat to human well-being, to other species and to the Earth as we know it might well be ourselves. The issue of population size is always controversial because it touches on the most personal decisions we make, but we ignore it at our peril. m0s50-m1-13

The coral's stinging armoury isn't used only for collecting food; they also use it to fight. As has been discovered only comparatively recently, corals, like many animals that live on land, are extremely territorial. But in order to see the battles, you have to speed up time.

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. To which I reply and say, "Well, it's funny that the people, when they say that this is evidence of the Almighty, always quote beautiful things. They always quote orchids and hummingbirds and butterflies and roses." But I always have to think too of a little boy sitting on the banks of a river in west Africa who has a worm boring through his eyeball, turning him blind before he's five years old. And I reply and say, "Well, presumably the God you speak about created the worm as well," and now, I find that baffling to credit a merciful God with that action. And therefore it seems to me safer to show things that I know to be truth, truthful and factual, and allow people to make up their own minds about the moralities of this thing, or indeed the theology of this thing.

Immensely powerful though we are today, it's equally clear that we're going to be even more powerful tomorrow. And what's more there will be greater compulsion upon us to use our power as the number of human beings on Earth increases still further. Clearly we could devastate the world. […] As far as we know, the Earth is the only place in the universe where there is life. Its continued survival now rests in our hands.

This City in Ukraine was once Home to almost 50 thousand people. It had everything a community would need for a comfortable life. But on the 26th of April 1986, it suddenly became uninhabitable. The nearby Nuclear Power Station of Chernobyl exploded. And less than in 48 hours the city was evacuated. No one has lived here since

How is it that [birds] can withstand the pull of gravity that keeps the rest of us tied so firmly to the ground? The secret is a wing with a thick, rounded front edge that curves gently downwards toward the back edge which is very thin. As thin, in fact, as a feather. As the bird glides forward, the air flowing under the wing is impeded by the wing's downward curve so it becomes slightly compressed, and that pushes the wing up. At the same time, the air flowing across the top of the wing is deflected upwards by the wing's front edge, so reducing its pressure. If the air is moving fast enough, then the slight suction from above, combined with the push from beneath will be enough to lift the bird into the air [...] and ample to keep it aloft.

If we and the rest of the backboned animals were to disappear overnight, the rest of the world would get on pretty well. But if they were to disappear, the land's ecosystems would collapse. The soil would lose its fertility. Many of the plants would no longer be pollinated. Lots of animals, amphibians, reptiles, birds, mammals would have nothing to eat. And our fields and pastures would be covered with dung and carrion. These small creatures are within a few inches of our feet, wherever we go on land – but often, they're disregarded. We would do very well to remember them.

Penguins underwater look somewhat like dolphins, and indeed the two families have similar evolutionary histories. Dolphins are descended from air-breathing land animals, just as penguins are descended from air-breathing flying animals. Both subsequently took to swimming for their food. They became beautifully adapted and streamlined. And now, both are superlative swimmers and highly accomplished fishermen.

If we [humans] disappeared overnight, the world would probably be better off [making the point that the reverse is not true].

This is the last programme in this natural history, and it's very different from all the others because it's been devoted to just one animal: ourselves. And that may have been a very misleading thing to have done. It may have given the impression that somehow man was the ultimate triumph of evolution, that all those thousands of millions of years of development had no purpose other than to put man on Earth. There is no scientific evidence whatsoever for such a belief. No reason to suppose that man's stay on Earth should be any longer than that of the dinosaurs. He may have learned how to control his environment, how to pass on information from one generation to another, but the very forces of evolution that brought him into existence here on these African plains are still at work elsewhere in the world, and if man were to disappear, for whatever reason, there is doubtless somewhere some small, unobtrusive creature that would seize the opportunity and, with a spurt of evolution, take man's place. But although denying a special place in the world may be becomingly modest, the fact remains that man has an unprecedented control over the world and everything in it. And so, whether he likes it or not, what happens next is very largely up to him.
