Three environmental groups want Lawrence to reduce the use of plastic grocery bags by imposing a ban or fining shoppers who use them.

The Lawrence Journal-World reports that the Sustainability Action Network, the Sierra Wakarusa Group and the Lawrence Environmental Teams United for Sustainability are taking their proposal to a city advisory board next week.

California and cities and counties across the nation have already instituted plastic bag bans. Some Kansas communities have considered the issue, although no bans have been instituted so far.

Thad Holcombe, of the Sierra group, says it’s time to stop talking about the issue and discuss some actions.

The item is on the advisory board’s agenda for its Wednesday meeting.
