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].
