text: In source 1, "In German Suburb, Life Goes On Without Cars," residents of the "upscale community" of Vauban, Germany, have become "suburban pioneers" and "have given up their cars." Although in many cities around the world it is unimaginable to give up your cars, it has become increasingly beneficial towards the environment and community. It is said to be "a huge impediment to current efforts to drastically reduce greenhouse gas emissions from tailpipes," as cars are responsible for "12 percent of greenhouse gas emissions in Europe, and up to 50 percent in some car-intensive areas in the United States." Planners are now taking the concept to "suburbs" where "stores are placed a walk away, on a main street, rather than in malls along some distant highways," thus making the car-banning residential friendly, and environmentally helpful. Not only will the limiting usage of cars be beneficial towards the community, it will also be beneficial towards your mental health as said by Heidrun Walter who stated "When I had a car I was always tense. I'm much happier this way."
