text: Eventhough cars cause greenhouse gas, air polution and death they are also very help full because if you have to go late at night to get food you have a fast way to get to the market because u have a car right out side your door. Also if something happens to your son in school or if u or someone needs medical attention you have a fast way to take them to the hospital or to get to were they are. But theres a down side if you go out to see what happend to you son in a hurry you probably going to have a car axcident and get seriously hurt or worst. Too many people use too many cars the streets are always crouded with cars at all times and some of these people drive crazy or they try to show of there car by going fast and end up getting killed or killing someone els.
