This is just a stream of consciousness thought process here but:

Can organic = sustainable -Not always
Can organic = locally produced (i don’t think it can yet)  There are many inputs that you just can’t get locally.  It can be locally finished in terms of meat or locally grown but not entirely locally produced (wouldn’t it  be nice though)
Can sustainable = local?  For all farms, I don’t know.  I think it may be more likely than organic.  
Any thoughts?
