An amazing gallery of earth images. Looks like Christmas lights in the snow. But they are also depressing. Those lights also represent, loss of space for wildlife, diminished overall resources, rampant destruction of trees and waterways, overpopulation, loss of nighttime skies, depletion of ocean fishes, and runaway greenhouse effects. Some say, we're going through another "mass extinction", which, if true, means that even man will be cut down to a few hundred, just like last time.
