It's crazy to think that the stuff we give complicated monikers like "organic/clean/biodynamic food" was, way back in the day, simply just "food."
I had to look up "biodynamic". Apparently, biodynamic agriculture
was invented in 1924, and includes such practices as putting chopped oak bark in an animal skull, and burying it to unleash cosmic forces.
Interesting stuff, but I don't think I'll be applying it in the garden this spring. The local eldritch monstrosity might misinterpret my intentions. And I'm fresh out of skulls, anyway.
As far as I can tell, the term "organic food" doesn't mean much, anyway. Certified organic farmers can still use pesticides, they're just somewhat restricted in which chemicals they're allowed to use, and the chemicals they do use can still be plenty toxic. I grow my own vegetables in the summer, and eat local produce when it's handy, but I consider "organic" to be little more than a marketing term.
I'm pretty sure my ancestors (who probably lived through the winter on potatoes, sausage, and sauerkraut) would have been ecstatic to have access to the same variety of food I can get at the local grocery store, whether it was labelled organic, or otherwise.
