That's a fair and valid point. I should have expanded on the list of possible factors to include living in a "bad" environment in general, where "bad" can be defined by a huge number of things, including poverty, hopelessness, and a million other things to numerous to mention... other than the one single factor of "air pollution" that this article suggests is the reason for depression and suicide. That was, after all, the point of my comment, in case you missed it; that idea which the article seems to promote - that air pollution causes suicide - is highly questionable.
