In a classic episode of the Simpsons, Homer becomes Sanitation Commissioner. Not suprisingly, Homer's management of the garbage pickup leads to a financial crises. To solve that financial crisis, Springfield starts taking in the nation's garbage.
In Naples, Italty instead of Homer Simpson the sanitation comission is controled by the Mafia. Which has been accepting trash from all over italy (as detalied in this article). Now the streets are so filled with trash that residents are setting them on fire (link).
Maybe Naples needs a new sanitation commissioner, may I suggest former Springfield comissioner Ray Patterson.
