>In their review, Meyer-Lindenberg and van den Bosch found that some potential threats had been examined more thoroughly than others. For some, including pollen, there wasn’t enough information yet to show a convincing link to depression.

The article gives me the distinct impression that the author is in denial of the stress associated with living in a crowded place. I doubt that it has to do much with fumes in the air- stress is a side effect of spending all day hustling, bustling, and competing. The popular opinion in the zeitgeist is that urban development is a good thing- so any bad effects are treatable. Adding green space may be a decent way to treat the symptoms of city living, but I think it will always be a stressful, mental illness-inducing lifestyle.
