In my own way.
  For just a moment, I imagine all the people it took to get the
  food to my table. I try to imagine all the places my food came
  from (a little map in my head) and visualize the ships and
  trucks moving it here. All the workers, from planters up to
  supermarket cashiers.
  Sometimes I envision the cross-breeders through the centuries
  that made the plants or animals what they are today. The people
  who made the table I'm sitting at, and the chair that keeps my
  ass off the ground.

  And grateful for the great pick-your-name-its-all-the-same-to-me
  that brings it all together. God as a word has so much baggage
  attached I don't even like using the word myself.

  In my mind, I just say,
  "Thanks".

  and covers all of that. [I don't always KNOW where all my food
  came from specifically, because I'm too lazy to read "origin
  country" but I imagine where it _might_ have come from].
