text: Cars are a great invention but it is not necessary for every individual to have one. Walking and biking are better alternatives. The use of cars has gone through the roof creating problems around the world. A healthy environment for our children and grandchildren is what we imagine. One does not think of using a car as damaging to the enviornment until after they have done it. Limiting car usage would turn the world into a healthier, stress reduced place. For these reasons I think it would be of best interest to try and find other alternatives to driving as much.                 Dear Principal,
