If you look at it ecologically, deforestation is high on the list of things which bring devastation. You cut down trees to build homes, for fuel, and you end up with no trees left, and you have to move on. If you take the earth as a whole, eventually there's nowhere to move on to.

I like New York. There are similarities with London that make it feel rather like home, but at the same time it's slightly fictional.

I'm a trained lawyer, after all, so I don't have to admit to anything.

I am going to have to stick to the script. If I muck around with the words it will defeat the object.

I like to think of myself as a natural gardener.

I've always liked trees. And then, growing up, I took an interest in ecology, hedges being destroyed, the landscape being turned into prairies.

I remember being in China and realising how irrelevant not even Britain is, but also Europe. We're just another remote country that hardly impinges on some places at all.
