There has been a profound shift of thought during this day and age about how the environment is being negatively affected by emissions and how vehicles play a great role in it. The first source stated, "Passenger 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."

For example, Heidrun Walter, a media trainer and mother of two said, "When I had a car I was alaways tense. I'm much happier this way." This proves that limiting car use would not only help the environment but it would better the people as well.
