How do we get democracy at the international level? That's our problem. and it's essentially the same problem people faced in the 18th Century when they tried to get democracy nationally. Now we need it internationally.

I'm a radical reformist, because between where we are and where I want to go there's a great deal of work, and I won't see the end of this.

What I worry about is climate change, because that would have untold effects that we can't even measure yet.

Having enough to eat, being able to educate your children, have reasonably stable employment, and being able to live in a society which isn't collapsing around you-all of these things have been generally eroded.

I used to work a lot on food issues and every time somebody predicted that production would be inadequate they got egg on their face a year or two later.

The question is not only what is grown but what it's used for. There's not going to be a mass transformation of dietary habits in rich countries-on the contrary, the first thing people do when they become more prosperous is to buy more meat.

There are a lot of people who don't contribute anything to consumption and production.
