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 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 do find myself surprised by the comedy shows that seem to have the same joke week in week out.

My favourite plant is the foxglove. I think they are a perfect balance between being a garden plant and a wild plant, as at home in woodland as they are in a city.

If I ever had any vanity, then I definitely lost it by being on television. It doesn't do you any favours in terms of showing you what you look like and what your emotions are.

It's true, people don't imagine I'd be particularly woody.

I am attached to the west coast of Scotland - it's gorgeous to look at and challenging. You have to contend with the possibility of being blown away or rained on. And in the summer months you can be eaten alive by midges.
