text: Bogota, Columbia dedicates a day to transportation without the use of personal cars, where the city's goal is "...to promote alternative transportation and reduce smog". Many who visit Bogota during this time are impressed by the "revolutionary change" they see unfold before their eyes. Going "car-free" leads to more physical activity amongst residents and an overall nicer-looking community. "Car-free day is spinning into a big hit in Bogota" by Andrew Selsky claims "Parks and sports centers... have bloomed throughout the city... sidewalks have been replaced by broad, smooth sidewalks... restaraunts and upscale shopping districts have cropped up.". Not only does the city reduce the amount of greenhouse gas it contributes to the atmosphere, but it results in a more active and better-looking community.
