Some estimate that nearly half a billion birds meet their untimely fate each year when they crash into the side of a towering skyscraper, or die from exhaustion after being mesmerized into flying endless circles by the building's lights. While removing the physical obstacles is out of the question, experts have found that dimming, or darkening, the lights works miracles when it comes to saving our feathered friends (in one study, it reduced bird deaths by 80 percent).

Earlier this month, General Motors CEO Fritz Henderson said in reference to the possibility that the automaker may move its headquarters from Detroit: "We're looking at, frankly, everything within our business, but it's not like we have that queued up at the top of our list. We don't have any such plan... but if we did it would be motivated by business rationale, which would be cost, efficiency and speed."
One upside to a faltering real estate market is a plethora of good buys on property. General Motors took advantage of that fact by purchasing its Renaissance Center headquarters in Detroit for $626 million in cash. For another $200 million it picked up a couple of office buildings in Pontiac, too.
