text: All vehicles alike release carbon emissions into the atmosphere, polluting the air and smogging our cities. Suburbs, especially, rely on automobiles to provide needed transportion. Experts state that car transportation in suburbs "is a huge impediment" (Source 1) when discussing "efforts to drastically reduce greenhouse gas emissions from tailpipes" (Source 1). In the car-intensive areas of the United States, passenger cars hold responsibility for "up to 50 percent" (Source 1) of greenhouse emissions. This constant car usage pollutes American skies. Elisabeth Rosenthal states that car usage reduction "will have beneficial implications for carbon emissions and the environment" (Source 4), especially in America "since transportation is the second larget source [of emissions]" (Source 4). Cutting down on cars for alternative, public, or group transportation provides a solution to the car epidemic of suburban America.
