Los Angeles rang in the 2014 New Year with a ban on the distribution of plastic bags at the checkout counter of big retailers, making it the largest of the 132 cities and counties around the United States with anti-plastic bag legislation. And a movement that gained momentum in California is going national. More than 20 million Americans live in communities with plastic bag bans or fees. Currently 100 billion plastic bags pass through the hands of U.S. consumers every year—almost one bag per person each day. Laid end-to-end, they could circle the equator 1,330 times. But this number will soon fall as more communities, including large cities like New York and Chicago, look for ways to reduce the plastic litter that blights landscapes and clogs up sewers and streams.
