text: It's been said that in Bogota, Columbia a Car-Free day was started from a progam that was spread to many countries. Millions of the columbians ; hiked, biked, skated or took buses every time it was consideres a car-free day. Like Bogota Mayor Antanas Mockus mentions in paragraph 23 source three, "It's a good opportunity to take away stress and lower air pollution as well". It gives people chance to explore places not only in fours wheels but at foot or in any other particular way. All the driving rule is not done for unfairness or harm but to be more careful and safe with the enviroment that we all live in.
