The problem:
Plastic bags are forever. The thin sacks that hold our groceries, toothpaste, and takeout meals have little hope of being recycled, and instead just might be reused as liners for our trash cans or containers for our dogs’ waste, after which they find themselves either blown into storm drains and rivers or hopelessly clogging landfills. According to one 2009 estimate, some 100 billion of these bags were used a year in the United States and somewhere between 500 billion and 1.5 trillion worldwide.
How it worked:
More than 400 laws and ordinances across the country ban or tax plastic bags, according to Jennie Romer, an attorney at the Surfrider Foundation and a leading advocate and expert on plastic bag policies. The bans actually started outside the United States, with Bangladesh banning them countrywide in 2002 and Pakistan announcing recently that it, too, will ban single-use plastic bags. “Our slight change in habits will do miracles for future generations,” one politician wrote.
In the United States, bans were spurred by a wide range of environmental groups, especially those concerned with oceans and waterways like the Surfrider Foundation. Plastic bags and other plastic products can easily wind up in rivers, storm drains, and oceans, creating massive floating patches of garbage and threatening marine life. (Activists are already moving on from plastic bags to encouraging bans on plastic straws and foam food containers.) California passed the first statewide ban in 2014, after several local governments had already banned single-use plastic, including San Francisco, which did so in 2007.
