Ein Kugel Eis: 1€
One scoop of ice cream: 1 euro (at least at some places). But that's not the best part. The best part is that, provided you get it in a cone, the cone has no paper wrap, and they don't automatically hand you a paper napkin... So it's potentially zero waste... At least as far as what I might call "pure waste"... I'm sure there's energy "waste" for freezing, etc., but no just purposeless waste. Or waste only for advertising purposes. Or waste "just in case you might need it (the napkin).
Just a little tiny step away from the "Disposability Consciousness" that I recently heard being talked about by someone named "Julia Butterfly Hill", who I intend to learn more about in the near future.
