re: World wide shortage of grain fixed easily.......

The US will be fine. You can grow wheat just about anywhere here, like 90% of the front lawns in the US are good enough... If it comes down to it I will till the front yard and fill it with wheat. It would take dustbowl conditions... and I think we could handle a drought like that better today because we can grow more food in less space and have more infrastructure to move water around.
