When did you realize you like micro/macro?

What do you say to being a human in a world with a macro civ much like our own, where you take the billions of, as an example, potato crisps[chips] made, packaged, sold, then consumed each yr, & just... swapped the crisps with humans? Macros regarding & thinking of you almost exactly as someone does a crisp. Thoughtless mass vore, by the handful from the snack bowl. Also; in this scenario, based on your preferences what would the macros look like/species?
