text: Although some may say, we need cars to get to work or to go to the grocery store, they can always just use public transportation. Buses are already running even if you are in a car so why not use them instead of polluting the air even more. In Bogota, when they have their car-free day, most people either "hiked","biked", "skated" or "took buses" as a mean of transportation. More evidence shows a senario where the Environmental Protection Agency is encouraging a "car reduced" community, stated by Elisabeth Rosenthal. Resources such as this one shows that if the United States Evironmental Protection Agency is concerned about our pollution rate why shouldn't we? If we cut down on our use of cars, pollution rate can drop extremley down causing a better living environment.
