Factors influencing the changing needs would include climate with changing and sometimes drastic weather, other neighboring societies and their relationships, food availability, growing populations, belief systems, to name a few. The world grew smaller when our ancestors ventured out to explore what was beyond. Civilizations discovered other civilizations. Information was exchanged and shared as we continued to develop. Often what one lacked in materials and expertise, the other had in abundance. Ideas were shared. We shared, for example, more efficient ways of killing with gun powder. We shared diseases common for one group into a group where no antibodies had built up through successive generations of exposure. We shared building materials and sky scraper rose up. This shows that all these things link back to Necessity of
