BERLIN, GERMANY - SEPTEMBER 13:  A shopper fills a small paper bag showing the companylogo with nuts at the "Original Unverpackt" ("Originally Unpacked") supermarket on the store's opening day on September 13, 2014 in Berlin, Germany. The store offers approximately 350 different kinds of foods and household necessities, all without packaging. Store founders say they launched the idea in an effort to combat the "packaging insanity" modern society takes for granted. Shoppers can either bring their own containers or choose from ecologically-friendly containers at the store.  (Photo by Carsten Koall/Getty Images)
