text: I believe that limiting car usage is an important factor nowadays. Driving causes pollution which in fact harms our environment(14). Paris actually banned driving for a couple of days due to smog , which is a type of pollution. Paris motorists would have to pay a fine of 22-euros or $31 just to drive there cars(11). Paris has more smog than other European capitals(17). After all of this hard work of limiting car use, the smog actually cleared and people did not have to pay to drive anymore(19). Is limiting car usage helpful?
