Poop in Your Food? The circle of life


March 12th, 2014

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. 

Columbus GA will soon be selling human waste biosolids to farmers.

 

Cool, Clear Water Not So Simple


April 8th, 2013

 

The cold, deep, fast running water is the healthiest as it harbors the fewest bad bugs and bacteria.

Hello Eco- Mom!
Please explain to me why leaving water running is bad! Fresh water is a limited resource; how does running it and using it end up ruining the fresh water?!
Love, Your Daughter

Hello Wonderful, Curious Daughter,
In order for water to get to your faucet it must first:

  1. Be pumped from  sewers, storm drains, resevoirs to a water treatment plant. Pumping takes lots of electricity
  2. That water must be filtered, stirred (again more electricity) and treated (lots of not so nice chemicals)
  3. Bad stuff from filtering must be lifted out, transported somewhere (more electricity and gasoline to transport to waste disposal site)
  4. Good treated water must again be pumped from the plant all around the city through the water mains (again more electricity)
  5. If you’ve used hot water, there is also the natural gas or electricity used to heat that water that is just going down the drain to no good purpose


20% of energy in the US is used just to pump, clean and filter water. Even if you pour clean water back into the drain it gets mixed up with the dirty stuff and has to be re-pumped and re-cleaned endlessly.

Love,
Eco-Mom

PS. Here’s a wonderful design concept to clean your water at home.

 

Sustainable Dishwashing: No More Plastic Scrubbers


October 31st, 2011

Have you scrubbed a pot using one of those green scratch pads lately? Most of us have. Did you know that they are made of oil-based plastic that breaks down as you scrub and those small pieces go down your drain, into the municipal water treatment, are filtered out and end up eventually in the Bay and ociean? Along with microscopic broken bits of plastic bags and bottlecaps they become part of fish and crustacean diets. Plastic has now become a defacto part of seafood flesh – yum, yum.

Solution? Loofah & agave scrubbers. Loofah (my sister grew some in LA one year) & agave are plants. Loofah can be purchased as a yarn if you have time to knit or crochet your own scrubber. As for me, 3M recently introduced scrubbers from agave (found some at Target) but there are probably others (let me know in comments).The sponge part of the old double-sided scrubbers has been natural sponge but with chemical dyes (bye-bye purple, orange, blue). The new sponges are made of recycled paper and natural fibers and have no chemical dyes.

Loofah, natural sponge, paper, yarn are components of these manufactured and handmade scrubbers.

I’m less enthusiast about the 3M soap loaded scrubbers. Soap is phosphorus free and scrubbers are from recycled plastic, but, again, plastic bits into the water stream. Their wipes are from bamboo, rayon (pulpy part of cotton plant), cotton & corn, presumably new material since recycled isn’t mentioned but all are compostable. Read labels & go online for details.

Remember, you don’t need to see scads of bubbles for a dish detergent to do its job. Though it seems counterintuitive, rinsing with cold water is best because bacteria thrive in warm (i.e. temperatures that our hands can handle) water but not cold.

Absorb grease and other food stuck to plate with old napkins, paper towels and put in garbage. Keep a strainer in the sinkhole. The more grease and food particles that go through your municipal water plant, the more energy they must use to clean your water.
