text: Over the years there has been a push to use more eco-friendly cars such as hybrids, or electric cars. But what about not driving a car at all? Many have made this change in Vauban, Germany where residents of this upper-class community have gone motor free, and given up cars. This suburban area alone is a  huge effort to reduce greenhouse gas emissions, similar to citizens in paris who have lost their driving privledges due to the extreme ammount of smog in their city. By banning odd numbered plates from driving on monday, and even numbered plates from driving on tuesday, pedestrians hopped on trams and bicycles to commute the rest of their day. Each time you firie up your engine, carbon monoxide and other pollutious gas is released into the atmosphere, causing a widening hole in the ozone layer affecting Global Warming. In this two-day restriction, smog was significantly reduced throughout the city.
