The Early History of Human Excreta
As humans kept wandering, they fertilized places along the way—especially those “rest stops” where their clans chose to stay for a while. Some of these early humans may have even noticed that plants tended to grow bigger, better, and tastier in such rest stops. So, tribes made a point of coming back to those spots the next season, or even several years in a row—and then, one year some decided to just settle at those convenient spots. These early settlers brought us to the advent of farming.
