Ethanol is currently produced by fermentation of corn. There are other ways such as the fermentation of whole plants, like "switchgrass", a native North American grass. How ecology friendly is ethanol — its use, it production by various methods?

I am doing a persuasive essay on ethanol and i needed to know what percent of air pollution comes from cars in America and i need to know how many people die from air pollution related causes in America. I also need to know how much does gas cost the average American. Thank You much!
