Every year, over one trillion plastic bags are used around the world. The average American consumer alone uses 300 annually. This ubiquitous item started out as a convenient and sanitary container for food, produce, liquids, chemicals, and waste. Plastic bags reduce paper use and use less material than comparable boxes, cartons, and jars. They are light, strong, and cheap. Today, however, their sheer number has caused major environmental problems. Most are not recycled, but thrown away, packing up landfills, clogging drainage systems, polluting the ocean, and killing wildlife.
