Over-sorting and over-grading on the farm and in the packinghouse, based on strict guidelines that have more to do with appearance (color, size, shape) than nutritional value or eating quality, leading to higher

Since cellulosic ethanol is created by using all of the parts of the plant being used (instead of the 10 %, mainly the
edible part, of the plant), in all likelihood, if this process turns out to work as advertised, we could use the
discarded parts of corn, or non-
edible plants such as switchgrass, so
food production would not have to be drastically increased.
To highlight the shocking amount of
edible food that is thrown away every day, this young man is biking across Europe, eating only
discarded food.
