The California Assembly voted yesterday to ban single-use plastic grocery bags in stores. The bill, which now moves to the state Senate for approval, would require shoppers to carry reusable totes or pay five cents or more for a paper bag made of partially recycled content. If passed, California would be the first state in the nation to have such a ban. Each year, Californians use 19 billion plastic bags, or approximately 552 bags per person. Is getting rid of plastic a good idea? How would the new rules affect your shopping habits?
