While sitting in English Comp my Prof. used a sample essay against smoking which obviously high-lighted the negative effects. It discussed second hand smoke, health effects, and the other usual "STOP SMOKING!" jargon. The class was all agreeing and talking about how bad it is for non-smokers in the proximity of a smoker, children, the environment (the things emitted and butts as litter), etc.
I did an arguementative essay and had to present via PowerPoint entitled "Please Keep Smoking". It discussed the effects of the vehicles those same class mates had and their emissions, the problem with childhood obesity and how it harms more children in America than second-hand smoke, the litter produced via tossed Starbucks cups, McDonalds bags and other random "vehicle" trash, and the effect on the economy if all major tobacco industries went under and the loss our economy would experience due to the taxes they pay, jobs they provide and more.
I originally did it just to prove that too many people jump on the band wagon of anything that "sounds good" or that they've been told all their lives. The research opened my eyes more than I expected and there was more than enough information readily available to complete the assignment in a fairly short amount of time.
Got an 'A' and it's now being used by the Prof. as a student sample.
