As we report in Sources Say this week: "On July 1, single-use plastic shopping bags will be illegal in Seattle, part of an effort to keep plastic out of landfills and waterways. "It's the dumbest thing in the world," a QFC employee, not speaking on behalf of the store, told Sources Say, who was shopping for Emergen-C. "There is still other plastic that will end up in a landfill, so banning one type of plastic in one city won't solve the problem.""
