Environmental activists are pressing cities around Oregon to ban disposable plastic shopping bags.
The bags are already banned in Portland, Eugene and Corvallis.
Now, anti-plastic bag campaigns are getting underway in Salem, Bend, Ashland, Lake Oswego, Beaverton and Tigard.
The Statesman Journal reports that 800 people have already signed a petition asking the Salem City Council to pass a plastic bag ban ordinance.
The push follows the failure of a statewide bag ban bill in this year's legislative session.
Supporters of a bag ban argue that the bags are difficult to recycle, are made from non-renewable resources, and pose a threat to sea birds and marine animals.
