text: Not only is the world becoming healthier as a whole an advantage to lower car use, all the way down to our communities would become better also. "The day without cars is an improvement campaign that began in Bogota in the mid-1990s." People go a whole day without using cars, with the exception of buses or taxis, and those that do use cars get fined. The citizens bike and hike and enjoy life without breathing in the smog that usually plagues the air. This event has caused some major improvements to the city. "It has seen the construction of 118 miles of bicycle paths, the most of any Latin American city, according to Mockus, the city's mayor." Also, "Parks and sports centers also have bloomed throughout the city; uneven, pitted sidewalks have been replaced by broad, smooth sidewalks; rush-hour restrictions have dramatically cut traffic; and new restaurants and upscale shopping districts have cropped up." This entire city has reaped the benefits of just one day without cars. Citizens here have not only began to improve themselves, but have also improved the world around them.
