I think it is really strange that no one knows where their food comes from. You have no idea usually from what farm or what region the food comes from and when it was harvested or added to the store. I imagined it would be nice for someone to set up an FDA backed system that stamped all products each time they changed hands, so that if you were in the grocery store, for example, and picked up a package of bread, you could see all of the stamps such as:

07/03/02 Fairbanks Idaho FarM ID 
07/03/02 Mac’s Trucking, Fairbanks, ID
07/04/02 CRISCO distribution NJ 
07/09/02 Sam’s Delivery, NYC
07/09/02 Corner Market, NYC
