During our project Meet the Food You Eat, we often debated on whether the scale was the right metaphor for measuring the environmental impact of food. The first prototype we presented to the class resembled the traditional balance like the one pictured above. This caused a lot of confusion with our classmates because in their mind, this was not a tool for analytical measurement but a symbol of balance (good vs. evil, the scales of justice, etc…). This is why our final prototype did not use the form of a hanging balance, but instead a beam balance typically found in science classrooms, kitchens, etc…
Anyway, it is good to see this metaphor being used other places. The image above was from a French newspaper article about carbon emission and orange juice. Thanks for the link Yasmine!
