Bag Bans Expand Across U.S., Other Countries

San Francisco, one of the first cities to pass a bag law and the source of the 2007 ruling, began enforcement on expanded regulations Monday. Originally limited to grocery stores and pharmacies, the city now prevents the use of disposable plastic bags in all retail stores. A similar ban also began enforcement that same day in San Luis Obispo County, Ca., and Santa Cruz, Ca. voted 4-1 to expand its bag ban last week.
