Cars are the main cause of pollution in major cities. Cities are covered in smog from gas emmisions from a car's exhaust. This is not good for the environment. Something must be done about this. If the usage of cars is cut down, then the amout of pollution in the air will be less. A less usage of cars allows people to have a clean community and helps the environment.

In Germany, there is a small community that is completely car-free. This community, Vauban, has about 5,500 residents, and not a single one of them use a car. This community is very clean and all of the people that live there are happy. Just think, what if every family in Vauban had a car? It would completely change this happy, clean community. There would be a lot more pollution and more stressful citizens. More and more small towns are beginning to ditch the cars for walking and taking a bicycle.

More cities are starting to have car-free days to help with the pollution problems that are caused by automobile engines. Examples of these cities include Paris, France and Bogota, Colombia. Pollution is starting to be a big problem in big cities like these, so they have decided to take action. Pollution is destroying our atmosphere. The gases that are released from the exhaust of car engines slowly deteriorates the layer of atmosphere of our world. If cars begin to be frequently used like they are now, the atmosphere may become damaged beyond the condition for being fixed. Earth only has one atmosphere, so once it's gone, we can't get it back.

People in the United States are beginning to cut back on the number of people who drive cars. The U.S. has been one of the leading country with the number of people who drive cars and the amount of pollution, but people have been taking action and going for a greener alternative. In the fourth passage it says, "A study last year found that driving by young people decreased 23 percent between 2001 and 2009." A lot of people between 16 and 39 do not even have a driver's license. People are starting to take public transportation and carpool instead of driving their vehicles from point A to point B. With more and more people doing this, it just lessens the amount of emmisions in the atmsophere more. America has passed it prime for driving because of the more and more who are taking action in making a change in the health of our world.

In conclusion, there are many reasons that we should start to lessen the amount of people driving on the road. It just causes pollution and makes the health and well- being of others and the earth worse. People are already beginning to make a change, but we need more than there is to make a difference.
