The climate suits me, and London has the greatest serious music that you can hear any day of the week in the world - you think it's going to be Vienna or Paris or somewhere, but if you go to Vienna or Paris and say, 'Let's hear some good music', there isn't any.

The only acceptable way to solve ecological problems is if you can persuade people to have fewer children. In the Victorian times, there were families of 15 children. Someone like Edward Lear, he was the last of 21 children. And so what we have to think about is offering people the alternative choice. And in the West, that's what's happening.
