text: In Paris there had been days of near-record pollution. To help clear the city's air Paris enforced a partial driving ban. Monday, moterists with even numbered liscence plates were forced to leave their cars at home or pay a $31 fine. Rejecting the fine resulted in having your car impounded. As a result 60 percent of congestion was down in France's capitol. The smog due to car usage was cleared enough on monday to rescind the ban for odd numbered plates the next day. In Columbia a similar day is taken place every year. A car free day where people hiked, biked, skated and took buses to work instead of driving their cars. If you violated this you would be fined $25. Even in rainy weather people participated just to help lower stress and air pollution. This campaign has sparked a revolution. It has also created the construction of 118 miles of bike paths, parks, and sports centers. It has caused the replacement of pitted sidewalks with broad smooth ones, cut traffic, and new resturants and upscale shopping districts have appeared. If every country had a day like this we could make a unbelievable difference.
