text: A very important way in which car usage affects our lives is pollution, many places around the world are trying to impose taxes and fines in order to keep people from over-relying on their cars. "After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city", things like this are quite obviously why the ecosystem is not at it's worst yet. One of the most polluted cities in the world Beijing competition for Paris until law enforcers stepped in to resolve the issue. Another city fighting pollution caused by car use is Bogota, who has once again banned it's over 7.2 million population from using their cars on the "Day Without Cars" event. The Day Without Cars is an event that if not followed could be penalize citizens most likely monetary fines of around $25 dollars, although some were even arrested for not complying with this method. Described by Andrew Selsky as a "program set to spread to other countries, millions of Colombians hiked, biked, skated, or took buses to work during this car free day". Not only is this helping out the rest of the world is bringing people closer as more people go to parks, sport centers and spend time together.
