text: When you have no path to travel on when it comes to a problem that must be solved, make the choice to talk to your peers, family members, and other people in your community. This can allow you to have different opinions, make friends, and feel better, in order to work through your tough problems successfully.Transportation is the second largest source of America's emissions (Rosenthal 34). Global warming is becoming more of an issue as time goes on,  part of this problem is vehicles and their pollution they let off. People are getting more and more worried about this as temperatures continue to rise on Earth. They are trying to do something about it. One of the more popular suggestions to help solve the issue is to limit car usage. I know, it seems pretty bizare due to the fact that some towns, such as my own, do not have everything citizens need within a walking distance. Benefically, "stores are being placed a walk away, on a main street, rather than in malls along some distant highway.(Rosenthal 6)". It is thought that it will "drastically reduce greenhouse gas emissions from tailpipes...Passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe... and up to 50 percent in some areas of the United States (Rosenthal 5)". People also are not putting forth an effort to help decrease the pollution by buying hybrids, instead they buy Diesels. Diesel gas has more pollutants then regular gasoline.
