All people have to do drive less and walk more or just drive less you don't even need to walk, but the less we drive the less polluted our world can be the better it is. People in Europe who live in Vauban, Germany which is a suburbed area, most of the people there dont use cars; 70 percent of the families that live in Vauban do not use cars and 57 percent of the 70 should there cars to move there. A population of 5,500 people, more than half of them dont use cars; now that sounds crazy but it works the area is less polluted and that life style is being adopted around the world in attempts to see if we the people can be less dependent on our cars and use them less.
