We had no school lunches...brown bag lunches made that morning for us. We did have Copper Country Dairy milk, white or chocolate...but that dairy is closed now. From time to time, one of the classes would have a sloppy-Joe sale, or a hot dog sale...and you did not need a lunch that day. (I've had hot dogs here there everywhere, but you have not tasted a good hot dog until you've had a Vollwerth's hot dog.) The money the class made...sophomore, junior, or senior...the money the class made was put in an account that enabled them to go on a class trip their senior year, one of the last weeks of class. Harvest time our lunch had a lot of garden produce. Now I think they feed the kids two meals at school...or some of them. I doubt our lunches were "highly-nutritious!" something that "nine out of ten specialists agree!" on. How much food is wasted? How much food is tossed? How far would that food go to those who really need it?
In service we had "wet garbage"...food not eaten...this on a ship w/less than 300 on it...through the chute on the fantail and into the water it went...to the little fishies swimming in the sea. In port, the call would be passed over the 1MC, "Wet garbage"...and two sailors would take the galvanized garbage can...two mess-cooking sailors...and they'd carry it off the brow of the ship to a truck that had a small dumpster attached. Hogs ate it, I suspect.
So how much food is wasted? Given to the hogs. All in the name of "nutrition".
