The world is getting smaller and smaller. All participants to this conference are the best example for that: we come from all over the world to discuss themes related to our daily food. Living in a small world has great advantages but also some drawbacks. We like to think we are ready for a major up scaling of our food supplies, but are we really? What do we need to answer to this challenge? How can we manage these large scale operations? Where do we get useful information? How do we discriminate useful information from misinformation?
