In our world, air pollution is a huge problem. Most air pollution stems from motor vehicles. People don't usually tend to think that driving is hurting the Earth, but that is exactly what it is doing. Smog is a big issue in cities like New York and Paris. Not only is it unsafe for the environment, but it is also unhealthy for humans.

Big cities have recently started doing "Car-Free" days where no one is allowed to drive. If a person does drive, they will get fined. City officials are doing this in an attempt to cut back on the air pollution and smog that cars cause. In a sense, they are saving the world that we live in. In the third article, Carlos Arturo Plaza said "It's a good opportunity to take away stress and lower air pollution."

Another wonderful thing about limiting car use is this: It saves money. Gasoline is so expensive today. It is stressful to have to pay so much money for it. The prices constantly fluctuate and it's hard to keep up with. Yes, public transportation costs money. But it doesn't cost nearly as much as it would to fill up your whole gas tank.

A big problem in America is obesity. I think that this is partially because nobody ever needs to get up and really walk anywhere. Our car keys are at our fingertips and since we can so easily drive, we see no reason in travelling anywhere close in any other way. I believe that obesity in America would be greatly reduced if car use was limited. People would be out walking more and they would be engaging in more physical activity than ever before. It can do nothing but good for all of us.

I understand that some people label limiting car usage as "unnatural", but I don't think those people really consider all of the goodness in it. There are many advantages in not being so reliant on cars.

In conclusion, limiting car usage is not just the latest fad, but a new way of protecting the Earth and it's people. It is a way to keep the environment clean and functioning properly, as it should be. It is a way to make humans healthier and happier. I honestly believe that being less reliant on cars is a great thing, and I believe that it is the direction in which we need to go.
