Even though our data did not end up supporting our hypothesis is it is still important to reduce the use of cars or at least the quantity in which they pollute. Just because our data didn’t point to the direct link between automobile use and acid snow does not mean there isn’t one. Therefore it is important to reduce our automobile use. Public transportation is a good way to reduce the amount in which we use cars. Also choosing green transportation like bicycles and even walking can reduce pollution. Scientists are finding alternatives for fuel. The use of alternative fuels, such as biodiesel and ethanol, for light duty CI engines to approach the target of ultra low NOx and PM emissions is currently being studied. Recently the interest in the butanol as a viable alternative either single or blended with conventional based fuels both to cut the demand for fossil fuel and to reduce emissions of particulate matter without significantly increasing in NOx is growing. Also municipalities can reduce car emissions through urban planning techniques such as traffic calming initiatives, pedestrian walkways, decreasing parking availabilities, improving public transportation and even increasing taxes based on number of cars owned by an individual.
