Every time I walk outside I find at least one of these. Most of the time I find more. At first I thought they were transformers and picked them up because I thought they were pretty in a way. Then, a friend of mine who uses these informed me they were e-cigarette butts. Looks like a smoker is a smoker, and old habits die hard. Whether its regular cigarette butts or e-cigarette butts, these guys belong in the garbage, or perhaps they can be recycled, but they certainly do not belong on the ground, where they will inevitably get swept “away”…eventually to end up in the belly of a bird or fish. We can do better. Who is responsible?
