How Will 9,000,000,000 People Live Together?

The world's population has risen from two billion in 1930 to 6.8 billion now, with nine billion projected by 2050. Think about those numbers for a moment. More people will be added to the present population in the next 40 years than the entire world population in 1930. What will be required to supply 9,000,000,000 people with water, food, clothing, housing, transportation, education, entertainment, etc.? Where will they work and who will pay them? How will they relate to one another? What they believe will clearly play a role in the way they relate. If they believe that the protection, preservation and enhancement of the quality of life is their top priority in 40 years the world could be a more peaceful and safer place. But, if they believe that their mutually exclusive belief systems should be imposed on the rest of the population, the quality of life that we have experienced could steadily degenerate over next 40 years. Clearly the current trend of for the concentration of wealth in fewer & fewer hands has some dangerous implications. As the general unrest of billions of people increases their beliefs will be a major factor in determining what they do. In 40 years my oldest grandson will be younger than I am now, and my youngest granddaughter will be 43 years old. How old will you children and grandchildren be? What can we do to make their world better and safer?
