A: Shitty articles are good actually. Shit is fertilizer. Shit is rich in nutrients and promotes growth. Scrubbing the world of shit reduces cholera transmission but also increases the prevalence of autoimmune disorders. There's got to be a balance.

B: Too much fertiliser promotes weeds. This calls for weeding, not scrubbing the area with bleach. There’s got to be a balance.

A: On a well-managed, diverse, polyculture farm, bounded with hedgerows and grass strips, with living roots in the soil at all times, there should be very little bare ground for weeds to sprout from! When new plants do emerge, it can be hard to distinguish friend from foe until the plant has at least put out a few leaves. Allowing the weed to grow and then strategically chopping and dropping the plant just before it flowers and sets seed creates a maximum amount of biomass for ground cover, which both protects existing soil from erosion and decomposes into new soil over time. Weeds are a resource if you know what you're doing.

If your intellectual ecosystem doesn't contain at least a modest quantity of horseshit, it's probably closer to desiccation and desertification than it is to thriving and flourishing. Shortage of nitrogen-rich inputs is often a limitation on growth, which is why the guano politics and the Haber-Bosch process were a thing. If people want to haul their shit to us and drop it off, that is good. It saves us the trouble of transport and we are (currently, not necessarily forever) a strong enough system that we can handle this free resource.
