“ We cannot seem to help ourselves they said. Thus, the hominid spark of intelligence flares, burns everything around it, and fades. Some humans will survive the great conflagration. Thus, begins an endless cycle of destruction spiraling downward until our species is gone. We can hope that before the sun begins to become unstable (it is about half way there now) evolution can produce a new and better intelligence that will have sufficient breadth and depth to understand the ecological consequences of its actions. ”
