text: In source 2 by Robert Duffer: Paris bans driving due to smog is important because after the day of pollution, Paris enforced a partial driving ban to clear the air in the city. For example, in paragraph 14 said "Congestion was down 60 percent in the capital of France after five days of intensifying smog..... The smog rivaled Beijing, China, which is known as one of the most polluted cities in the world" what this mean is that if the cold came and there are warmer days this can caused the layer in the air to trap the car emissions, which then will create pollution. If we stop the used of car driving this will help the environment around us.
