EL PASO, Texas —When people talk about the dangers of smoking, they are usually focused on the health risks, and hardly on the damage that cigarette pollution does on the environment. People walking the streets of El Paso can see the beautiful Franklin mountains that rise from the city and the brilliant red sunsets. As they appreciate the unique environment, they also can see cigarette butts littering the sidewalks. Cigarette butts are all over the UTEP campus, especially on the floor next to the cigarette ashtrays. Dr. Elizabeth Walsh, a biology professor and a member of an environmental advocacy group, said she usually see smokers outside the biology building flip their cigarette butts right next to ashtray.
