In Philadelphia, Pennsylvania, the cost of trying to remove this graffiti pollution comes to $4 million annually.

Modern vandals destroy upward of $100 million annually in the United States alone; New York city’s bus and subway vandals cause $2.6 million a year in damage. A common form of vandalism by youths is the breaking of windows of schools, of railroad trains and the windshields and the rear windows of autos. On just the Long Island Railroad (in New York state, U.S.A.), more windowpanes are broken annually than in all of France.

In one beautiful 690-acre wooded preserve, not far from New York city, youths do $100,000 worth of damage annually to the facilities.
