text: Personal automobiles and cars have played a major role throughout the world since the invention of the car in World War 2. Cars have been a very successful invention and many people drive their own every day on their way to work, school or other places their feet cannot carry them. Though the car has fulfilled its duties in making the lives of humans easier, it has also contributed to many negative events. For example, car emissions get trapped in the atmosphere and cause living things to breathe in dirty air around them. Therefore, a revolutionary idea has been spreading around the world: using personal automobiles less. The new aspect of using cars less has promoted a happier society, a cleaner environment, and an open attitude towards alternative transportation.
