Final answer:
No-car zones lead to cleaner air, improved health, and less traffic. The reduced exhaust emissions improve visibility, as fewer pollutants in the air mean you can see farther on clear days.
Step-by-step explanation:
The advantage of having no-car zones like the one implemented in the city center of Bogotá is primarily the improvement in air quality. With fewer automobiles in densely populated areas, there are reduced exhaust emissions leading to cleaner air and consequently, less traffic. This reduction in vehicular traffic does not only mitigate congestion on the roads but also lessens the noise and the release of pollutants into the atmosphere, which are major contributors to smog.
Smog significantly reduces visibility and is harmful to human health, contributing to respiratory problems and other illnesses. Cleaner air means a reduction in these health hazards, and you can see farther on days without smog because there are fewer particulate matter and other pollutants obscuring the view. Moreover, decreased air pollution helps protect the environment by minimizing the impact on ecosystems and contributes to the overall wellbeing of residents and wildlife in the area.
