Lately, there has been a sharp decline in the birth rate of populations around the world. This is one of the factors leading to the decline of civilization. At the end of the Roman Empire, there were problems with a sharp decline in birth rates among the Roman elite and in the cities. Many Romans, especially those in the upper classes, preferred to have fewer children. The conquered territories were increasing, life was getting better, and people wanted to have fewer offspring. This was accompanied by a sense of security and comfort. Ancient Egypt and other faded civilizations also had fertility problems at the end of the era. We need to reflect on these statistics. It's hard to realize any solution, but things seem to be heading into World War III.
