For most of human history trash was not picked up. Garbage removal consisted mostly of either burying trash, burning trash, or leaving trash where it fell. What can this lack of garbage removal tell us about our past? Quite a bit it turns out. Archaeologists frequently sift through garbage from ancient civilizations to find out how they ate and lived day to to day. Archaeologists have even found old beer recipes from Ancient Egypt in the trash of the Pharaohs.
