"Growth, growth, growth, that's all we've known... World automobile production is doubling every ten years; human population growth is like nothing that has happened in all of geologic history. The world will only tolerate so many doublings of anything--whether it's power plants or grasshoppers." (M. King Hubbert, 1903-1989)
