[samsara15]

Eventually, we will reach a limit, no matter how long it takes. The population cannot continue to increase geometrically forever, and there is a limited amount of space and resources. Even the universe is finite in size. I suspect it will indeed be a very rude awakening, when we encounter that limit. Many cultures in the past have done so. The Anasazi, the Norse in Greenland, Easter Island, the Mayas, and many others.
