I've been looking recently at the following argument but cannot see what the main conclusion is?
It has been proven that a smoker who quits smoking can reduce their risk of cardiovascular disease to almost that of someone who has never smoked. Thus, quitting smoking is beneficial for the quitter.
But also quitting smoking is beneficial for the whole society. For example, the essays collected in the book “After Tobacco: What Would Happen If Americans Stopped Smoking?” show that if America became truly smoke free, the social, economic, and health consequences would be profound. To name just a few societal benefits demonstrated in that book, if every American smoker stopped smoking in 2006 by 2025 there would be almost 3 million deaths avoided and this would lead to a saving of $211 billion in health care costs. More than that, the American people quitting smoking would result in a massive surge of productivity in all industries across the American economy.
It is more or less safe to extrapolate the general tenor of these findings to a lot of other societies with similar social, economic and environmental conditions, Australia included. Thus, every Australian smoker who quits does good both to themselves and to the Australian society as a whole.
Is it the last sentence of the first paragraph, or the last paragraph? Or neither? Could someone please identify and explain to me why. Thank you
