text: The United States should definetly start having an annual car-free day not only to reduce pllution, but to promote exersice and the outdoors. How fantastic would it be to see more and more people riding their bikes to a park or to a friend's house? If you need to get somewhere, you might as well enjoy your ride by getting some fresh air and some exersice. A reduced amount of time would be spend on the roads because there is less traffic, and that causes less accidents and people will feel much safer. Alternative transportation would also create happier and stress-free lives; who doesn't want that? There are plenty more positive effects on the topic of less cars then there are negative ones, so why not begin this "smart planning"?    Seeking multiple opinions can help someone make better choices because they can get different perspective from other people, more option to choose from, and other ways to solve problem. Things can go really bad sometimes if someone doesn't ask for more than one option to choose from.
