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

On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.

If I ever had any vanity, then I definitely lost it by being on television.

I don't think I'm really a rude person, but now I see myself on television, I think, 'Oh, God, that is a bit strong.' And I wonder if I've always been like that and I haven't been aware of it.

I like being forced to think about things in a different way.

I try to make myself walk around a bit, but I probably think about it more than I actually do it. Years ago, I did think about joining a gym.
