text: Another reason that i think we should cut down or completly get rid of driving and cas is to cut down on green house gas emisions. in the second scource it says "paris had 147 micrograms of particulate mater or PM. compared to other contries in the world that only have 114 or 79 micrograms PM." (source 2) this goes to show that just one of the smaller cities in a smaller contrie is emitting this much pollution into the air imagine how much the U.S is or china is emitting daily. when paris found out abot this they made sure that no one was driving for the next few days to "clear the air". and when the driving ban lifted there was already an increase in the clenleness of the air after only a few days of not a lot of people driving. And the people who were caught driving were givin a fine for driving. if we want to stop the green house gas emisions we as a contry and even a world need to find ways like what paris did to "clear the air" cars alone make up 12% of the green house gas emisions. now imagine our contry and planet if we were to completly cut out that 12% percent. we can do that as long as we can come up with ways and guide lines and rules to limit the use of cars.
