text: Furthermore, studies show that in the United States people are buying less cars than before and less people are retaining their drivers license. This is something good because one of "President Obama's goals is to curb the United States' greenhouse gas emissions." This shows how many people are trying very hard to reduce car usage which will reduce pollution. Even young people who are considered rebels of the streets are taking this into consideration because studies "found that driving by young people decreased 23 percent between 2001 and 2009.." People are aware of the changes that are going on like what a professor said "different things are converging which suggest that we are witnessing a long term cultural shift." Reducing or limiting car usage or not using cars at all will not only help you, it will help your neighbors, your family, and most important the earth, where we live in. Take it for granted that this will change the world once again.                                          Dear TEACHER_NAME,
