Recently an email came through decrying that produce was grown in human poop and that Chinese suspend chicken wire crates over the fish ponds and the fish with their shit. While this sounds sensational, in truth, human manure was a standard farming nutrient prior to the flush toilet.
I am not overly concerned about chicken poop or people poop – where do people think dirt comes from? it’s worm & bug poop (also known as castings). The “Circle of Life” is not just a cute song from the Lion King – creatures eat predominantly other creatures – bones, stomachs, poop and all. Cows & horses poop on the land that grows the grass that they soon graze on. Human poop starts as food and is simply food that has been burned as fuel or excess nutrients that cannot be fully absorbed at the time. Allan Savory in his TED presentation establishes how new deserts have been re-established as verdant grasslands by re-introducing traditional cattle herding whereby the droppings both enrich the soil and contain the grass seeds for reseeding.
We need those excess excreted nutrients over and over again each day and they need to return to the food stream through the soil, though a diet entirely of poop is probably not very well balanced and should be mixed with veggie matter for a full-bodied compost. Composting and percolation through the ground to underground aquifers (except those exposed to fracking or other underground toxins) exposes excrement to the pro-biotic bacteria necessary to cleanse it for eventual safe reabsorption into plants. The Rich Earth Institute in Vermont does just that with collected urine (rich in nitrogen, phosphorous & potassium) in a [rpcess they call “peecycling” which is used after it is pasteurized !
That being said, excrement of sick humans and animals should be contained and kept out of the food stream.
No less an authority than our founding father, George Washington, considered people and horse casting to be more valuable than gold. Though he was many things to our nation, he considered himself, first and foremost a farmer. He studied it, saved seeds, used crop rotations, fertilizers, was intimately knowledgeable about the micro-climates of Mt. Vernon & the 8,000 acres he maintained for his wife’s family around Virginia. He built lovely “necessaries”, outhouses, throughout his estate from which the proceeds were harvested regularly and encouraged everyone to use them. The farms were extraordinarily prolific and provided all the food for the family and 300 workers.
Amish have been recycling their refuse regularly though some municipalities are now requiring them to put in leach beds.
