We are a food exporting nation, but only if we can grow the food... what we saw in the midwest, which is a key area for food growth - think corn, oats, wheat, soy beans, beef, pork, poultry....... if crops fail to grow, there will be nothing to export.
Farmers, already, can't afford to buy grain to feed their livestock, which means they have to sell less than optimal livestock for horrifically, low prices.....
