Would Anyone Like to Comment?  How much do you care about quality of life 500 years from now?  How many people might there be then?  What are the chances that Earth’s resources will be sustained that long?  How would you characterize quality of life then?  What about applying “complex” systems engineering to mitigate potential consequences of “overshoot”?  What does that mean?  How much might the overshoot likelihood be reduced?  T o what extent is human life sanctified compared to other living entities?  How much should we do to keep everyone alive?  How much should those not yet conceived be desired, welcomed and nurtured?  What if the world’s population growth continues unabated? What might we do to motivate lower fertility rates in coming generations?  Let’s at least have more dialogues to elicit some pros and cons concerning answers to these questions.

My Motivation  This is a highly controversial subject, and one needs humility.  It takes courage to even bring it up, particularly in professional forums.  After a long career I no longer answer to an employer but could be ostracized or ignored by others.  I believe in reducing population growth as a worthwhile cause, and want to stimulate more attention and support to the issue.  More eloquent and serious advocates than me have failed in this.  (Connor 2006), (Daly 1996) , (Ehrlich 1968, 1990, 1994), (Friedman 2008, 2011), (Meadows et al. 1972, 2004), (Senge et al. 2008)  I’d be satisfied if systems engineers question and resist suggestions that would exacerbate the sustainment problem.  I think we should all try to enlighten and advise decision-makers to only pursue those courses which are more likely to benefit the long- term viability and quality of life of the human race.  My frustration: Why would anyone want more people other than for selfish reasons, short-term benefits, and profit motives!?

The Paper  Purpose  Call attention to danger of overpopulation already expressed by many learned and respected researchers  Bemoan the fact that most dismiss the warnings, ignore the long term, and few care to take any corrective action  Apply complex systems engineering principles in suggesting actions  Means  Interchange among fictitious characters expressing their opinions  Attempt to induce shock at how many additional people might result if a group of people devastated by “disaster” instead survived for 20 generations, even at a relative low birth rate of 1.3, say  Show how birth rates of just 1.0 or lower would solve the problem and help ensure maintaining or improving quality of life  Way forward  Suggestions to incentivize future generations to have fewer children The 7 th International Conference for Systems Engineering 4 5/22/2014 of the Israeli Society for Systems Engineering, 4-5 March 2013

The Characters Character Name Character Type Role in Dialogue Earth Concerned by human behavior that ignores planet's Biggest stakeholder in sustainability long-term interests Complex Systems Engineer Focused on advice for systems engineers concerning Emphasizes complex systems behaviors and complex what might be more effective systems engineering principles Systems Thinker Knowledgeable about complex systems, smart, and Provider of balanced and objective viewpoints and ideas dispassionate for research Facilitator Concerned with fundamental issues, abstract ideas, Leader in posing sustainability concerns and significant progress toward solving human made problems Panel of Judges Collective voices of intelligence and morality Responding spirits (supreme beings, departed parents, overseeing all thoughts and acts spouse, and closest friends) to facilitator Liberal Supporter Concerned with human welfare and favoring Voice of compassion government action Conservative Advocate Believes in individual freedom, right to life, and Naysayer limited government Optimist in solving “world hunger” Agriculturalist Interested in growing food production worldwide through petroleum-based fertilizers provided by fossil fuels This characterization (and ensuing dialogue in the paper) is used to elicit a (more) balanced set of opinions.

Some Facts  [In 1900] the entire world population was less than 2 billion people. … in 2012, [it]… exceeded 7 billions. The world’s population [was] growing by 200,000 people a day!, but [both] death and birth rates have declined over the past several decades. (World Bank) (Population 2012)  China is first in population with 1,347 billion people. India is second with 1,241 billion, and the U.S. is third with only 312 million people (Population 2012)  The 2012 estimated population growth rates of China, India, and the U.S. are 0.481%, 1.31%, and 0.899%, respectively; the world’s is 1.10 % (Factbook1 2012) The 7 th International Conference for Systems Engineering 8 5/22/2014 of the Israeli Society for Systems Engineering, 4-5 March 2013

Overpopulation Pressures  Keep Every Human Life Sacred.  Save Lives No Matter What the Cost.  Provide Food and Water for All Starving People in Africa.  Ignore Greater Water Shortages.  Lament Loss of Life in Natural (and Other) Disasters.  See next chart  Hype Impossible Rescue Attempts.  Pay More for Doctors’ Futile Test and Treatment Recommendations.  Pursue Voluntary Charitable Initiatives.
