> How will a country that has no money and terrible credit do when it needs to import 50% of its food?

Food prices have already been skyrocketing. As the article points out, austerity has tanked the Greek economy despite repeated predictions by European 'experts' that any minute now, austerity would cause Greece to turn a corner. Why do you think food prices would get substantially worse?
