Global imo not the USA. US is not a net importer of food, but an exporter. Most of the imported food can be grown in the states also three of the top four food imports to the US are used for/are beverages i.e. wine, coffee, and malt beverages. Also the reason why so much money went into ethanol research is because of the massive corn wastage that happens every year. Maybe the US should crank up food export, but demand is for wheat not corn.
