24/7 Wall Street – One of America’s largest states by population has roads littered with items that people have thrown away. The litter ranges from cigarette butts to bottles and aluminum cans. Researchers say they have little hope the problem will get better soon. The nonprofit Keep Pennsylvania Beautiful had field teams visit 180 locations to examine trash next to roads. The number was extrapolated to get a total of 500 million pieces of litter along the state’s roads, both rural and urban. Thirty-seven of the items were cigarettes. Another 30% were items made of plastic. Plastic items could take decades or even centuries to decompose.
