The Paris mayor’s office has seen fit to launch an outdoor ad campaign to keep Paris clean.  The image of trash in one or other natural environment is headlined with “unacceptable” or “scandalous” in Paris, too!  To the extent that photos of trash in Paris would have not had much impact, this is quite a good execution.  Of course, when you know how little recycling goes on in Paris, you wonder on the consistency of the effort.  Dog litter is also rather unacceptable in my mind.  Meanwhile, how about those pigeons?  Are they not right up there as the foulest, polluting element… aside from us human beings, of course?
