We have to rethink how we're going to live on this earth - stop talking about the fact that we've got to have agriculture, we've got to have exports, because all that is the death of us.

I think it's pointless asking questions like "Will humanity survive?" It's purely up to people - if they want to, they can, if they don't want to, they won't.
