text: Cars, especially in America, are a major source of transportation. Without them many people would not have an easy way to commute to where they need to be. But, convience is causing more pain than pleasure and startign to harm our enviroment. Cars just by themselves cause around fifty percent of the greenhouse gases that are emited into the atmospere. Similarly they cause twelve percent in Europe (par. 5) Logically it would make sense to find the root of a problem and change it to make the problem go away, but in the case of cars, cars are a root in the pollution problem, but many people need them to ge to get where they need to be. The easiest solution to this is to limit our car use and add more busses and easier, more acessable areas for bikes and walking. Pollution will lower and people will still get to where they need to be. Pollution is a major topic regarding the safety of our enviroment and cars have been a proven source of much of the pollution in the air. Using less cars coensides with less pollution in our surroundings. Paris, France was suffering from very high pollution in the air. To combat this, for five days certain people, based on their lisecense plate number, were not allowed to use their cars. Though not everyone complied, after the five days the smog went from the levels found in the worst city for pollution, Beijing China, down by sixty percent (par.14). In just under a week Paris went from being the most polluted it had ever been to a better, safer level. If a city just by limiting the car usage by half was able to make such a drastic difference in that time, imagine it being limited more over a wider area. There is a possibility of totally correcting the pollution problem worldwide, or at least making it better and more easily handled. Although the enviroment is important, cars are also affecting the way we interact as people in a community.
