I can think of one thing that will change the world: Stop manufacturing mugs. Frequenters of church sales, garage sales, and second hand shops know that there are far too many of them. They sit, dusty-like, with logos from obscure and now-defunct companies or, if they're more cup than mug, wait forlornly for the return of their saucer. Stop buying mugs. Let's recycle the ones we have before we manufacture anymore. You're allowed to break all the really ugly ones. Thank you
