KEY POINTS:
What are you doing personally to make a difference?
I catch public transport to and from work most days. Compost. Try to eat as locally and organically as possible. Force my children to garden. And I'm about to launch a magazine about sustainability.
What more could you do?
There's always more you can do. I could put on another jumper rather than turning up the heat. Stop dying my hair with horrible chemicals. Teach the children to use less toilet paper.
What is your biggest environmental sin?
I find it hard to walk past a cheap, sparkly top straight off the boat from China. But I'm getting better.
Global warming - man or nature?
There's too much scientific evidence to even have this debate any more. The challenge now is to work with nature to get ourselves out of this mess.
