text: The United States of America had long been one of the world's most prime car cultures. It is the birthplace of some of the very first car models. A lot of big cities in the U.S have a huge amount of driving going on. For example, New York City, San Fransico, Miami, Los Angeles, ect. This is leaving the country with a large amount of pollutants in the atmosphere. After President Obama's ambitions to decrease the amount of diesel fuel use, recent studies have shown that Americans are buying fewer cars, driving less and are even having a decrease in the amount of licenses permited as each year passes. In 2013, the amount of miles driven per person was about 9 percent under the usual American peak. With the large amount of citizens living in this country and the number of people only rising, this small decrease has had a very positive effect on the environment.
