text: Places such as Paris and Bogota, Columbia have noticed the unhealthy amount of smog in the air so they decided to do something about it and the result was exactly what they were hoping for. In Paris, days went by with near record pullution levels which made them decide to do a partial driving ban to reduce the smog. Their intentions were to have even number starting license plates leave their cars at home the first day while the following day, odd numbered plates were to do the same thing. After the first day, the smog had reduced so much that they lifted the ban before the second day. In Bagota, it has been their third year in a row banning cars for a day (with the exception of buses and taxis.) The smog and air pollution reducion in these two places alone is massive! Not to mention the amound of money they have saved.
