In the future, things are going to change drastically -- including our diets. Whether it be from the destruction of arable land, food processing technology becoming cheaper, or just plain ethnocentrism, eventually, real food will become a luxury item, unavailable to all but perhaps an elite few. So, what does the rest eat? Processed foodstuffs, based usually on soy or yeast, loaded up with artificial flavors and engineered to be nutritionally complete -- but not the least bit tasty or satisfying. If you discover to your horror that the artificial food is people!, that's Human Resources.
