It's a question that many people don't know the answer to. And it's an increasingly complicated answer once you start breaking down our complex food system. In our Garden Science classes, we try to make it simple: all our food comes from the soil.
We traced a cheeseburger back to the soil, breaking down the main ingredients and mapping them out. It looked like this:
Bun - flour - wheat - soil
Tomato - soil
Lettuce - soil
Cheese - milk - cow - grass or corn - soil
Meat - cow - grass or corn - soil
The students then illustrated their favorite food and traced its ingredients back to the soil. In this picture we have tacos, pasta, icecream, and mashed potatoes all traced back to the soil.
