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

One of the main reasons for the conflict in Syria, and the terrorism that it’s spawned, is climate change and drought.

I think we’re going to find, with climate change and everything else, things like global warming and goodness knows what else and the cost of fuel for a start, that things are going to become very complicated.

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.

I sometimes wonder if two thirds of the globe is covered in red carpet.

Do you seriously expect me to be the first Prince of Wales in history not to have a mistress?

I was totally absorbed. I was in another world, or another dimension; all sense of time evaporated.

As technology advances at an alarming pace, the place of drawing remains as valid as ever in the creation of art and architecture.

The demand for organic food is growing at a remarkable rate. Consumers have made it clear that they want organic produce and every sector of the food chain is responding, with the kind of results we have just seen.

A jostling scrum of office buildings so mediocre that the only way you ever remember them is by the frustration they induce – like a basketball team standing shoulder to shoulder between you and the Mona Lisa.

The price of apparently cheap food is costing nothing less than the Earth!

There is no doubt that we live in an age of unprecedented, and sometimes terrifying, technological advance where the speed of advance so often outstrips the necessary ethical considerations.

To avert disaster, we have not only to teach men to make things but to teach them to have complete moral control over what they make.

Forests are the world’s air-conditioning system-the lungs of the planet-and we are on the verge of switching it off.

All I’m saying is that there is a price to be paid at the sharp end environmentally and everywhere else for the food that is produced in a particular way.

My Rainforests Project has three main elements. Firstly, to determine how much funding the rainforest countries need to re-orientate their economies so that the trees are worth more alive than dead.

Your greatest achievement is to love me.

There’s no room for doubts when you have dreams as big as yours.

You are what you think. So just think big, believe big, act big, work big, give big, forgive big, laugh big, love big and live big.

Big or small, I appreciate everything that’s done for me.

We live in a strange world, where we think we can buy or build our way out of a crisis that has been created by buying and building things. Where a football game or a film gala gets more media attention than the biggest crisis humanity has ever faced.

Because philosophy arises from awe, a philosopher is bound in his way to be a lover of myths and poetic fables. Poets and philosophers are alike in being big with wonder.

If your heart was as big as your mouth you’d be real.

The toughest guys have the biggest hearts. The biggest hearts – because they have to be tough to protect it.

I’m a big personality. I walk into a room, big and tall and loud.
