There is a sufficiency in the world for man's need but not for man's greed.

A couple of years ago, the dining halls on my campus went "trayless."  This was intended to reduce food waste.  I think it was pretty effective.  I am just waiting for the dining halls to adopt my plan of "plateless" dining.  I think that will cut down on food waste even more.  "Yes, I'll have a handful of spaghetti, please!"
