Interesting finding, but the article at least leaves one with more questions than answers (I haven't looked up the original research). My own personal experience tends to confirm the main point put forth. Indeed, when we moved to the US Southwest several years ago, I thought I would miss oceans the most (having always lived on a coast). But no, I really miss seeing green -- my first time back east after moving here, the impact of seeing all those trees was really tremendous (& positive). Having said that, the effect mentioned in the study can also be due to the amount of attention that a city street demands, and a lot of other factors. (Walking down Broadway in NYC in the middle of day just isn't the same as strolling through West Village on a Sunday morning!) Not to mention what other commenters have pointed out, e.g., correlation != causality. Quite likely the researchers have thought about this; I would be interested in what they found.
