Street Graffiti

Europe
In Europe, community cleaning squads have responded to graffiti, in some cases with reckless abandon, as when in 1992 in France a local Scout group, attempting to remove modern graffiti, damaged two prehistoric paintings of bison in the Cave of Mayrière supérieure near the French village of Bruniquel in Tarn-et-Garonne, earning them the 1992 Ig Nobel Prize in archeology.
In September 2006, the European Parliament issued the European Commission to create urban environment policies to prevent and eliminate dirt, litter, graffiti, animals' excrement and excessive noise from domestic and vehicular music systems in European cities, along with other concerns over urban life.
