text: It may seem difficult at first but it is defiantly duable and effecient to put away vehicles all together, or atleast more often. Cell phones and all the new apps make it easier to communicate with friends, enabling car pooling and to maximize the fuel spent to speak to others. Gathered from source one, "Passenger cars are respnsible for up to 50% of greenhouse gas emissions in some car-intensive areas in the United States."

I am going to state facts from the the 1 st source through the 4th source.
