Before starting eating our snacks/lunches, we made a list of the items that were in our lunch bags and the origin of them. We then talked about the definition of a "food mile" and how even the foods we eat have carbon footprints. We then used a food mile calculator and figured out how many food miles they were worth. Our number was a startling: 556 305 kms. We then traced lines on a world map tracking the path of our food to Calgary.
