I had not thought about that question too much until I received a very alarming phone call.  One of the people that I spoke to during that phone call was a woman that I know personally.  I have known her for years, and I have visited with her in her own living room, and so I can vouch for her honesty.  She told me that her "son-in-law manages three organic food farms in California, Idaho, and Washington State", and that he is "warning family and friends to get ready for severe food shortages starting this spring".  Apparently there are several factors that will cause food supplies to be tighter, and one of the biggest is the fact that the "Ohio spill has contaminated a lot of land and water".  Apparently there is a scramble "to find clean food" and her son-in-law is receiving lots of phone calls from buyers in the eastern half of the nation that want to buy what his farms are producing.

We will just have to wait and see if things will be as bad as this source is suggesting.
