text: It is time the citizens of planet Earth envision the streets of Beijing and the historic city of London, not as images of pollution and car-reliant places, but as clean and healthy ones. The advantages of limiting car usage makes this dream a reality, because this policy betters the environment and creates a better lifestyle around the world. Hopefully word spreads quickly, and everyone, everywhere, knows of the advantages of limiting car usage, because only then, will our future be a bright one.                          If we limit car usage there would be less pollution, we would save thousands of dollars, and it would inprove our safety. So if you really think about it, less usage of cars would be a great impact for us in a good sense.
