text: The advantages of reducing our use of automobiles in the US are well worth the cost.  Transportation is the second largest contributor of co2 emissions, just behind power plants. (Rosenthal, paragraph 34) Cutting these emissions, even by a fraction would have great benefits to our environment. David Goldburg, an official of Transportation for America states, "All of our development since World War 2 has been centered on the car, and that will have to change, how much you drive is as important as whether you have a hybrid."
