permaculture

[Rain Tenaqiya <raincascadia@yahoo.com>]

It seems to me the only way to make farms sustainable is to compost municipal 
sewage and send it back to the farms that support the cities.  Whether this 
could be achieved without fossil fuels is the question.  My understanding of 
biodynamic farming is that there are no external inputs.  Is this sustainable 
over the long-term?  Is it possible to use deep-rooted plants and nutrient 
accumulators to create a nutrient steady-state in the agroecosystem?  Or is 
this just an unsustainable mining of the soil?  Whatever the answers, we need 
to move food around a lot less than we are right now and adding to the local 
economy by growing food for others is better than shopping at Walmart.
