My father grew up in rural Hawaii during the 20's and 30's. He basically lived on sugar cane as a kid, gnawing on raw stalks on his way back and forth to school each day. His teeth and general health suffered in the long term, to say the least.
Maybe, on balance, it will be a good change for Hawaii. But...the ideal of the sugar industry leaving The Islands seems like the last kick in the gut 2016 has for us.
