Cars emulate lots of dangerous gases that may harm our precious earth, many of which are responsible for the greenhouse effect. The greenhouse effect causes gases to be trapped in the atmosphere which harms our ozone layer and creates a smog-like appearance on our cities. Paris is an example of a polluted city as civilians battle against threatening smog from emissions of diesel cars in France (Duffer,8). Many actions towards progressive behavior have increased the likelihood of limited car usage, such as tolls throughout cities and fines up to $25 for violators of laws. These enforcements will ensure that the environment is capable of maintaining generation after generation at a stable pace.
