Haverhill may soon join the other 61 communities in Massachusetts that have banned single-use plastic shopping bags. City Councilors Michael McGonagle and Mary Ellen Daly O’Brien are leading the effort. “My kids call the bags ‘urban tumbleweeds,’” said McGonagle. “Eliminating them would pay dividends to the city for years to come.” Daly O’Brien encouraged Haverhill to follow Newburyport’s example and eliminate the use of the bags that may hurt the environment, especially wildlife. The council unanimously voted to charge the Community Advisory subcommittee with researching whether to require stores to use paper bags if shoppers do not bring their own reusable bags.Linda Greenstein can be reached at email@example.com.
