text: This movement is also starting in major cities such as Paris and Bogota. Paris was one of the most polluted places in Europe until motorist with even numbered license plates were ordered to leave thier cars at home and the same would apply to the odd numbers the next day. As the days went on the smog in the air had reduced and also the traffic had dropped. In Bogota motorist were also orderd to leave thier cars home. When the people were orderd to leave the cars at home  they started to ride bikes and carpooling to get to thier destination. The other countries saw how this helped car pollution and traffic jams they started to ban cars as well.
