text: An advantage of reduction of car usage is it helps develop a better environment to live in. Some areas which have cars create a lot of smog which is unhealthy for the environment. For example, "Congestion was down 60 percent in the capital of France, after five-days of intensifying smog" (Duffer). Smog is formed by cold nights and warm days which causes the warmer layer of air to trap car emissions. Without so many cars, this issue can decrease. It will help the environment progress and be safer for everyone. Statistics show that "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" (Rosenthal). Cars are causing air pollution. If cars are still the dominant transportation, the environment will still suffer from air pollution such as smog. It's safer to use a large vehicle such as a bus to get around because a bus can hold many more people than a car and would ultimately give off less gas than the population of people who use cars.  Another safe way around town would be vehicles which don't give off gases into the air such as bicycles. A safer environment is a better environment.
