Going through David Holmgren's version of the Permaculture Design Principles, here's #9.
Use Small and Slow Solutions
Let's start with physics for this one:
- From Classical Mechanics
F = ma
Force (energy) equals mass (size) times acceleration (change in speed)
If we reduce either mass or acceleration, we reduce the force necessary to effect a change.
- From Thermodynamics
Okay, thermo requires partial differential equations so I'll skip the math, and this one is more allegorical anyway.
Heat (energy) equals motion, so moving more slowly requires less energy.
- Buy locally/eat seasonally even if we don't grow it ourselves, but growing it ourselves is even smaller and slower (even if I have qualms about the poor energy math behind a lot of buying locally, but assume both the consumer and the farmer walk to the market)
- Save first, then buy (wait until you have accumulated sufficient energy rather than borrowing)
- Limit your marketable production to sustainable levels
I'm sticking with old politeness: Thank you for coming to my blog and I hope you have a great week!
