The PBS Newshour is showing a piece on food waste, featuring an effort in California. It is part of a weeklong effort. This particular one is laudable, featuring coordinators and software packages.
But my contrarian side is present whenever I hear an estimate of "pounds of food wasted". Looking at the produce shown, the pounds wasted include peach pits, watermelon rinds, etc. I know measuring the "waste" is hard, and maybe there is a benefit to using fuzzy statistics: they stir up activism. My instinct, however, is that better stats, more solid stats, are the way you build the base for a social movement, for changing norms.
