Nothing wrong about imported milk except the cost.  If locally obtained milk becomes more cheaper than imported milk, then Omidyar may have a case.  But since feed must be imported, I highly doubt that would be the case.  Nothing pleasant about living near a dairy farm where the smell of manure and presence of flies permeate the area.  Mililani once had a dairy farm in the Kipapa gulch near Kam highway but thankfully closed up shop.
