To improve the way on how we perceive the subject of excreta, let's start from a scientific perspective on the biological facts on how humans excrete waste.
the metaphor comes from a chinese saying "fertilizer goes in the owner's field", which emphasizes the beneficial nitrogenous properties for the plants, contributing to the benefit of humanity
