text: In the United States one out of every 4 person is obese, and the reduction of car usage will help limit the obesity rate. Walking or even biking from one place to another is a work out and that is a common way to lose weight. We try so hard to reduce obesity and one of the many ways to gain weight is to eat junk food and not jog, run, or walk it off. So reducing the limit of cars is a good idea to reduce the obesity rate in the United States.
