Here's one more reason to do all you can to preserve what's left of the natural environment: simply looking at a green landscape can help refresh your brain.
In a blog post at the New York Times, Dr. Andrea Faber Taylor explains that there are two forms of attention. One comes when you focus on a task at hand—reading a blog post, for example, and the other happens when you are drawn to contemplate running water or a distant view.
Urban environments offer little opportunity to exercise this "involuntary" attention, which is thought to alleviate brain fatigue.
No word on whether images of distant views have the same effect—but we do feel a bit better just looking at the image above, don't you?
