Is this a good thing? Maybe, although paper bags are not necessarily more environmentally-friendly than plastic. Paper bags take more energy and resources to produce than plastic bags. Plastic bags, however, last forever in landfills. There's not really a landfill shortage in the US and there never was, despite the worried cry of environmentalists during the 1980s. If we do a good job of recycling plastic bags (which we don't), are they really a problem?
