Here’s the thing, Japan imports about sixty percent of its food. Japan is, by any reasonable measure, over-populated.
If you can’t feed your population and if there is no reasonable prospect that you could feed your population, perhaps you have too many people?
Another country for which this is true is Britain, which imports about 80% of its food. Yet the British have also been importing over a million people a year.
