text: Smog in Paris, France and Bogota, Columbia have reached record pollutions and both cities do not want to deal with it any longer. Robert Duffer writes about how the Paris government enforced a new rule which allowed both even and odd numbered license plates to drive on a certain day and would alternate everyday. This was very beneficial, however some people needed transportation but would be fined $31 if their car was used on the wrong day. Being that Paris is one of the most famous capitals of the world, one would expect to see more smog than usual. Andrew Selsky also writes that in Bogota, Columbia, a day without cars was put into place in the 1990's and still continues today. Once a year, buses and taxis are the only transportation allowed in the whole city. If not obeyed, there would be a $25 fine. This day was put into place as an improvement campaign which also benefitted the city. Bike paths and smooth sidewalks were put in and during rush hour has cut the traffic in half. It also opened up restaurants and shopping malls which were widely used by the public. Both Paris and Bogata saw improvements in their environments without having so many cars on the road.
