It seems to be the thing now that young people are getting back into politics.

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

There's people coming in who've never done any politics at all, who've never been in a trade union, they've never been in a political party, they've never done anything, but they do feel a kind of urgency.

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 real fight is about what should be in the marketplace and what should not. Should education be a marketable commodity? Should healthcare?

If the economy becomes disembodied from society it can only lead to disaster.

Everything has to be done to build some sort of international democracy. We've seen only the tiniest beginnings of that.
