How is this an international problem of any significance? Japan is a net importer of food, not a major exporter. Radioactive crops lost will not be missed. The big story is fallout directly contaminating humans. It raises the question of safety in the long run and a review of the risk to profit evaluation. I have heard that plants could not be built without gov intervention because no private insurance could be obtained. If this is true we have one more example of failed central planning. How many more centuries will humanity suffer before government is abolished?
