To suggest that the world food shortage is caused by corn-based biofuel production is ludicrous. And you fail to mention that IPI sells mostly within the US where ethanol production is stronger than ever. You also aren't explaining an obvious missing piece to your scenario: If using corn for biofuel is causing global famine, then ending the use of corn for ethanol production shouldn't have any impact on the price of stock on potash producing companies because the demand for corn would continue, at least until world hunger is eliminate, if we accept your theory.
You also fail to reveal, in the interest of transparency, that you lost a lot of money on Intrepid by buying hight and selling low and were banned from Google because you were continuously bashing the company on its Google message board--in the interest of transparency.
