The U.S., Canada, and Australia are major exporters. Some parts of the former Soviet Union are also players in this market. Globally per capita wheat stocks have been a consistent seventy pounds my whole life, until three years ago when they sank to forty pounds. If we have one bad harvest, which seems likely given underfertilization, that number goes below some critical level and the civil disorder events in Egypt, Kuwait, and Pakistan last year become weekly rituals.

  I wrote more about the wheat harvest concerns on The Cutting Edge News and I'll happily share my spreadsheet of wheat stocks vs. human population.
