Solution for plastic bag

• The solution is not a plastic bag ban, which is an emotional response which fails to strike at the heart of the issue; instead of a market-based solution, a ban shifts production to paper bags and compostable bags, both of which have heavy environmental consequences.
• The solution is not switching to paper bags or compostable plastic bags. A study on the life cycle of three types of disposable bags (single-use plastic, paper, and compostable plastic) showed that both compostable plastic and paper bags require more material per bag in the manufacturing process. This means "higher consumption of raw materials in the manufacture of the bags... greater energy in bag manufacturing and greater fuel use in the transport of the finished product. ...The added requirements of manufacturing energy and transport for the compostable and paper bag systems far exceed the raw material use in the standard plastic bag system." (from a peer reviewed Boustead Consulting & Associates report)
     - Plastic Tax: In 2001, Ireland implemented a plastic tax (or PlasTax); the first of its kind, this route acknowledges the fact that people will still occasionallyuse plastic bags. This market-based     solution discourages daily, thoughtless use of plastic bags by charging a nominal fee per bag at checkout. In a study by the Irish Department of the Environment it was found that plastic bag usage had dropped 93.5%. This breaks down to a drop from 328 to 21 bags per person each year.
     - A cultural shift away from use-and-toss culture: Each reusable bag can eliminate hundreds (if not thousands) of plastic bags.
