text: Paris' pollution rates have been rising over the years and hit almost record level highs for a few days, so in order to reduce the amount of smog in the air there was a temporary car ban. One day anyone who has a even-number license plate was not allowed to drive. If you were caught driving you had to pay a fine that is equalivant to thirty-one U.S. dollars. The smog miraculosly cleared up quickly and people were able to drive again. Another city in Columbia, Bogota, holds a "Day Without Cars", once a year. Citizens are allowed to use public buses and taxis during this day. The government is trying to advocate for public transportation and smog reduction. Most people walk on this day and even though it has rained on this day before citizens participated just the same.
