text: Americans need to understand that there is more to life then sitting and letting things happen for you. Go for walks, take hikes, rollerblade, plan a bike ride through the park with the family, theres more to life than cars and vehicles. Sure its nice to go somewhere without having to walk but sometimes its good to have family outings and its also refreshing and fullfilling to feel the crisp, cold air hit your skin, walking outside the house on a cold day.    Some cities are making themselves car-free. Like in Vauban, Germany; Paris; Bogota, Colombia; and even the president of the United States is trying to "curb the United States' greenhouse gas emissions" (Rosenthal, Paragraph 29). In Vauban, Germany residents of a community are "going where few soccer moms or commuting executives have ever gone before: the have given up their cars" (Rosenthal, Paragraph 1).Some advantages of limiting car usage is people are happier without cars and it promotes the alternative transportation and reduce smog.
