text: Safety is another reason to reduce car usage. Think about it, if pedestrians reduced their car usage by 50 percent the percentage of car accidents would also decrease. This could save many people's lives; animals as well. Rosenthal said, "Cities could become denser, and better for walking", which also makes it safer. To go along with saving lives lets mention health. Americans are getting more and more unhealthy and overweight. It is a rising problem in our country. Many people die from it everyday; obesity can be stopped. One way to lose weight and get in shape is exercise. Imagine how much better shape Americans would be in if we actually had to walk to the grocery store or McDonald's. It would make us think "do we really need that?". Those extra burned calories count, sitting in a car does not burn many calories.
