David Attenborough Quotes

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.

Birds are the most accomplished aeronauts the world has ever seen. They fly high and low, at great speed, and very slowly. And always with extraordinary precision and control.

There are some four million different kinds of animals and plants in the world. Four million different solutions to the problems of staying alive. This is the story of how a few of them came to be as they are.

Sensing the approaching danger, the snail flees. But in a world of snail paces, the conch is something of a Ferrari. It calls for desperate measures. Exhausted by the effort of its last-ditch attempt, the tulip snail is slowly... gunned... down.

The savage, rocky shores of Christmas Island, 200 miles south of Java, in the Indian Ocean. It's November, the moon is in its third quarter, and the sun is just setting. And in a few hours from now, on this very shore, a thousand million lives will be launched.

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

Our imprint is now truly global. Our impact now truly profound. Our blind assault on the planet has finally come to alter the very fundamentals of the living world.

Sinking beneath the waves is a very surreal experience. Your first instinct is to hold your breath. At night, the reef is a ghostly world. Tiny shrimplike creatures dance in the lights. ... with little light, there is a lot less colour. But this is still a magical place.

Right now we are facing a man-made disaster of global scale, our greatest threat in thousands of years: climate change. If we don’t take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon.

Its heart that in flight contracted a thousand times a minute, slows until its beat is virtually undetectable. Its body temperature falls dramatically, and its breathing seems to cease altogether. [...] It's hibernating; but for a hummingbird, winter comes 365 times a year.

Reptiles and amphibians are sometimes seen as simple, primitive creatures. That's a long way from the truth. The fact that they are solar-powered means that their bodies require only 10% of the energy that mammals of a similar size require. At a time when we ourselves are becoming increasingly concerned about the way in which we get our energy from the environment and the wasteful way in which we use it, maybe there are things that we can learn from "life in cold blood."

People who accuse us of putting in too much violence, [should see] what we leave on the cutting-room floor. My conscience troubles me more about reducing the pain and savagery that there is in the natural world than the reverse.

Trade is a proper and decent relationship, with dignity and respect on both sides.

Those that live in the air have to fight in the air.

We are going to have to live more economically than we do. And we can do that and, I believe we will do it more happily, not less happily. And that the excesses the capitalist system has brought us, have got to be curbed somehow.
