PASADENA, CA - APRIL 22: Employees hand out free reusable grocery bags at a Whole Foods Market natural and organic foods stores which is ending the use of disposable plastic grocery bags in its 270 stores in the US Canada and UK on Earth Day, April 22, 2008 in Pasadena California. The use of reusable bags has increased since a statewide plastic bag recycling law was enacted in July 2007 requiring grocers to provide in-store plastic bag recycling and to sell reusable shopping bags. Some communities have banned disposable single-use plastic shopping bags because they don't break down in landfills, and clog waterways, endangering wildlife, and are a major source of litter.
