Then let's take two studies, same geography - the UK. Here are the POSTED references... I never use the term "according to" - I choose to post actual references:
http://www.medicalnewstoday.com/articles/244463.php
"Every year, 13,000 people in the UK die a
premature death due to emissions from cars, trucks, planes and power plants"
http://www.cancerresearchuk.org/can...vesmoking/smoking-and-cancer-secondhand-smoke
"Every year, second-hand smoke kills about 11,000 people in the UK from lung cancer, heart disease and strokes"
I see 13,000 per year dead due to second hand auto pollution, and 11,000 dead due to second hand tobacco smoke in the same geography. Please read the articles, and tell me if you see something different?
I should point out - I don't advocate smoking. I avoid trying to irritate others, and stick to designated smoking areas only. But I do feel that it's important to point out to others that just because they do NOT smoke? Doesn't mean that one isn't putting contaminants into the air in a significant fashion. About the only innocent person on earth is the fellow living off the grid, riding a bicycle every day.
