text: A home to 7 million people, Bogota, Colombia is trying to spread their program globally and reduce the pollution from the once nessecary cars. "The goal is to promote alternative transportation and reduce smog" (Source 3). Violaters are faced with $25 fines. In a car free day, "the turnout was large" (Source 3). It is believed to be a great oppurtunity to relieve stress and lower air pollution. Bogota's program is "generating a revolutionary change" (Source 3) and the idea is spreading across borders.
