An Atlanta woman is taking on Target’s use of plastic bags in a “Theresa versus Goliath” campaign. Theresa Carter, a native of Minnesota who is now living in Atlanta, has started an entity called “Customers who care.” In April, she launched a Change.org petition urging Target Corp. (NYSE: TGT) to stop the use of plastic bags. When asked why she chose Target, she explained that she is a regular shopper at the country’s seventh largest retailer, and it has limited alternatives to its single-use plastic bags.
