Money: The ROOT of all EVIL 
RE
Can't leave this one alone, RE.
The great one you are (mis)quoting actually said that the
LOVE of money is the root of all evil.
Money is just a medium of exchange, neutral and physically innocuous.
It's the damn greedy humans that screw it all up. That's why he said it the way he did.
I like this from JDWheeler:
3. Do not use more energy over the course of a year than can be collected during the year.
Not to be interpreted too strictly; for example, if you have a four-year coppice wood rotation, then you only collect 4-year-old stems, never dip into the 3-year-old ones.
As a corollary to this, or perhaps an Ordnung rule in itself:
No resource or potential resource shall be allowed to go to waste, but where possible shall be used to fullest potential. For example, anything edible by man, beast or bug shall be fed to the appropriate entity or as a last resort shall be composted. Additionally, all bodily wastes from said men or beasts shall be composted or otherwise used to maximize soil fertility.
I suggest this as a possible corollary to JDW's #3 above since this is very much an energy issue. All foods are "food" precisely because they embody the solar energy that was used to produce them (through plant photosynthesis, whether that food be a plant product, or the product of an animal that ate plants or ate other creatures that ate plants, and so on). All foods starts with plants, including phytoplankton and algae, the base of the ocean food chain, and grasses, which are a critical part of the food chain for us beef and cheese eaters.
That embodied solar energy persists through many generations of eaters as our wastes (as well as our ultimately dead bodies), and those of our livestock, are happily consumed by various critters, insects, worms, bacteria and fungi, etc. (each harvesting what energy it can by further breaking down the complex carbohydrates produced during photosynthesis) until the last carbon bonds are broken and all that remains are the humic substances that enrich the soil to produce new plants. lt is entirely an energy economy. Solar energy, that is.
It is foolish for us to not utilize every available bit of that energy as best we can, ultimately putting what remains back into the soil to be cycled back to us again by the action of water and sunlight.
