charge a fee for each plastic bag a consumer needs if they don't bring their own reusable bags

A few plastic bag facts:
1) U.S. uses about 100 billion plastic shopping bags/year
2) Plastic bags take up to 1,000 years to decompose in a landfill. THEY DO NOT BIODEGRADE
3) Hundreds of thousands of marine mammals die every year from eating discarded plastic bags mistaken for food.
Ireland introduced a plastic bag tax in 2002, and it works. Consumption has been reduced by 90%. Whole Foods eliminated all disposable plastic bags in U.S., Canada, and U.K. locations in 2008. I am extremely hopeful that the President will sign a petition asking for mandatory plastic bag tax in ALL grocery and convenience stores, such as Food Lion, Harris Teeter, Walgreens, and local gas station stores. This way, there is an initiative for consumers to bring their own bags when shopping for groceries.
