I'm swanning round the world looking at the most fabulously interesting things. Such good fortune.

If I can bicycle, I bicycle.

There is no question that climate change is happening; the only arguable point is what part humans are playing in it.

Do we really require so many gardening programmes, makeover programmes or celebrity chefs?

We really need to kick the carbon habit and stop making our energy from burning things. Climate change is also really important. You can wreck one rainforest then move, drain one area of resources and move onto another, but climate change is global.

I find it far more awesome, wonderful, that creation; our appearance in the world; should be the culmination, or at least one of the latest products of 3,000 Million years of organic evolution, than a kind of country trick, taking a rib out of a man's side in a trance.
