 Luis Fresco, president of Wageningen University in the Netherlands, welcome. The problems of health today, I would have thought that one of the biggest problems is antibiotic resistance, especially in the food chain. How do you deal with that? Yes, antibiotic resistance is an increasing problem because urbanization leads to the consumption of more animal foods. That's both from poultry and beef, but also from fish, and the more intensive productions just mean that more antibiotics are being used preventively. However, we do not need them because we can make sure that the hygiene is optimized in the production system. That means, for example, that animals should not be exposed to external factors, for example, so that stables or the housing they have is completely tied off. So there's no influence from the outside world. That's of course not the case in most developing countries, but it's quite possible to produce without a very, very little antibiotic lead. And we need to go in that direction because of the risk of crossing over. I mean, why hasn't it happened in a country like the United States, for example? I think it is because there is not enough pressure through law and through public opinion to really look into this issue. Also, there are areas of production that are not as close to human centers as there are, for example, in a densely populated country like the Netherlands or in China, for that matter. If you take a conference such as this, the World Policy Conference, is this actually a very good forum for discussing these things and can there be an impact on policymakers? I think it's very good that we discuss health in its wide implications here because usually we tend to concentrate on economic policy and trade. And this is such an underlying principle and factor and something that we really need to resolve, so it's very good to have it at this high level. Luis Fresco, thank you so much.
