text: America is also trying to get in on the anti-pollution ideas coming from Colombia and Paris. Since America's love for vechiles is starting to decrease they are now able to try and decrease the vehcile usage. Population growth is a high contributing factor in this because with this cities slowly become denser and denser allowing for people to be able to get to the places they need to be without a car. They can walk there along the many sidewalks in the city. In New York there is a program to share a bicycle which has increased the bridge and tunnel tolls for cars because of all the people who no longer use their cars making cars more expensive to drive. Their has also been a drop in the young adult getting their license because they simply do not need it."A study last year found that driving by young people decreased 23 percent between 2001 and 2009"(Source 4, 41). Which shows most people are slowly decreasing the amount of driving they do. Driving in America is not as nesscary as it was before and it shows.
