The whole of the 20th century has always put the car at the center. So by putting the pedestrian first, you create these livable places, I think, with more attraction and interest and character.

Climate change should be seen as the greatest challenge to face man and treated as a much bigger priority in the United Kingdom.

If you think about the impact of climate change, [it should be how] a doctor would deal with the problem. A scientific hypothesis is tested to absolute destruction, but medicine can't wait. If a doctor sees a child with a fever, he can't wait for [endless] tests. He has to act on what is there. The risk of delay is so enormous that we can't wait until we are absolutely sure the patient is dying.

We might be more inclined to think about the longer term if we were more aware of what is happening around us. Perhaps daily weather forecasts could include a few basic facts about the Earth's vital signs or details of where climate change is increasing the likelihood of damaging weather?

The sustainability revolution will, hopefully, be the third major social and economic turning point in human history, following the Neolithic Revolution - moving from hunter-gathering to farming - and the Industrial Revolution

Any difficulties which the world faces today will be as nothing compared to the full effects which global warming will have on the world-wide economy.

It is now 14 years since I first suggested that organic farming might have some benefits and ought to be taken seriously. I shall never forget the vehemence of the reaction.. much of it coming from the sort of people who regard agriculture as an industrial process, with production as the sole yardstick of success.

As human beings, we suffer from an innate tendency to jump to conclusions, to judge people too quickly, and to pronounce them failures or heroes without due consideration.

The whole of nature cries out at our mistreatment of her. If the planet were a patient, we would have treated her long ago.

It is vitally important that we can continue to say, with absolute conviction, that organic farming delivers the highest quality, best-tasting food, produced without artificial chemicals or genetic modification, and with respect for animal welfare and the environment, while helping to maintain the landscape and rural communities.

We need to be realistic. There is very little we can do now to stop the ice from disappearing from the North Pole in the summer. And we probably cannot prevent the melting of the permafrost and the resulting release of methane. In addition, I fear that we may be too late to help the oceans maintain their ability to absorb carbon dioxide.

Conflict, of course, comes about because of the misuse of power and the clash of ideals, not to mention the inflammatory activities of unscrupulous and bigoted leaders. But it also arises, tragically, from an inability to understand and from the powerful emotions which, out of misunderstanding, lead to distrust and fear.

We have spent the best part of the past century enthusiastically testing the world to utter destruction; not looking closely enough at the long-term impact our actions will have.

I think we'd be very foolish to expect that we can just import everything from somewhere else and imagine that that's going to last for ever and ever and ever

What I have been trying to remind people of for the past 40 years is that you can’t operate an entire conventional system, whether it’s economics, business or the way we live and surround ourselves, what we eat, without recognizing that there are severe negative externalities that are not being accounted for.

It is baffling, I must say, that in our modern world we have such blind trust in science and technology that we all accept what science tells us about everything - until, that is, it comes to climate science.

It is frightening how dependent on drugs we are all becoming and how easy it is for doctors to prescribe them as the universal panacea for our ills.

If you think about your and my grandchildren, this is what really worries me. I don't want them - if I'm still alive by then - to say, 'Why didn't you do something about it?', when you could have done.

You have to give this much to the Luftwaffe: when it knocked down our buildings it did not replace them with anything more offensive than rubble. We did that.

We don't, in a sensible world, want to hand on an increasingly dysfunctional world to our grandchildren.

If your children want to alter society, listen to their reasons and the idealism behind them. Don't crush them with some clever remark straight away.
