text: After looking of the causes and effects of limiting car usage , it all comes down to having a big influence on the world. It takes one area such as Bogota, Columbia to have a huge impact. In our every day lives , our car is our main resource for transportation, but this should change. Not only are you capable of helping to have a postive effect on the environment but so am I. This just shows how if we are all willing to come together as a  community, we are capable of creating a healthier environment. This is why the world should influence limiting car useage.          Dear,
