I am not totally ignorant about farming.  Use to belong to a Hui who farmed alfalfa for animal feed in Hawaii.  Our bales of field dried hay went to dairies primarily.  Dairy farmers remembered when their milk could not be sold because of the chemical contaminates found in the milk.  I also know when the pineapple companies sprayed heavily from overhead booms, with the misty clouds that would be carried by the wind into the neighborhoods.  We never sprayed our fields with chemicals, ever.  Want to talk about the diseases and health problems, especially among the healthy young males who worked the fields?  When you are an economic mainstay for the State of Hawaii, those in power seem to turn a blind eye and a deaf ear to the health threats to the people.
