A pedestrian carries a single-use plastic bag while shopping in the Chinatown section of Los Angeles, California, U.S., on Tuesday, June 24, 2014. California grocers, who could realize $1 billion in new revenue from selling paper bags for a dime each, are teaming up with environmentalists on a new push to make California the first state to ban plastic shopping bags. The retail and environmental lobbies, which backed many of 13 failed California bills since 2007 to curb or ban single-use plastic shopping bags, are facing off against manufacturers of both plastic and paper bags who oppose restrictions on the sacks.
