text: by Robert Duffer Paris recorded days of pollution soon after they decided to have a ban on driving to clear the air. The smog in the air due to the pollution in the air was in quote "rival to Beijing, China one of the most polluted cities in the world". Imagine if every country decided to have a national day or even a week of no cars the ammount of pollution in the air would significantley decrease. In reference to that in Bogota, Colombia thats exactly what they are trying to accomplish. Based on the article "Car-free day is spinning into a big hit in Bogota" by Andrew Selsky it has become the thir straight year cars have banned with only buses and taxis permitted for the day without cars in the capital city of 7 million. Since the mid 1990's an improvement plan began in Bogota know as "the day without cars" the plan is to ban all cars in colombia there efforts have even ended up spreading ideas to other countries such as Paraguay. With the limitations car use in these countries pollution will continue to decrease.
