text: In these last few centuries we have polluted the world more than anyone else has. This is due our technological advances. One of the biggist advance in these centuries is the motor vehicle. The car has now become a houshold item. Cars are one of the main reasons why our ozone layer is open and we responsible for "50 percent...of greenhouse gass emissions" (Roseenthal par5). It's shoking to see how far we have advanced but to see how much we have destroyed in the world at the same time is crazy. Paris has become so poluted that they had to get a "partial driving ban to clear the air of the global city" (Duffer par10). "Congestion was down 60 percent in the capital of france, after five-days intensifying smog" (Duffer par14). Imagine what would happen if cars were recuced in use for a month.
