text: Too many cars on the steets are poluting the air and thats not good for us because we are cutting down trees and we are going to run out of air to breath at some point if we continue like this. Thats why poeple should stop driving cars and ride a bike to there job or take the train. Also cars make geenhouse gas, cars are responsible for 12 persent of greenhouse gas emissions in Europe and up to 50 percent in some car-intensive areas in the united states. We are also going to have less death because many people die in car axcidents and becuase of drunk drivers and less kids are going to be getting hurt or killed if there on the street because they dont have to worry about cars hitting them. For example if a kid is playing with a ball and the ball goes to the street the kid is probably going to go get it but he wont get hurt because there are no cars on the streets.
