At some point I will read the articles, however at this time others things command my attention. It seems very interesting.
Ian,
I appreciated your comments. We have needed "family planning" on this planet for a long time (a massive understatement). As a human family on this planet, if we do not make the choice to do voluntary "family planning", the alternatives and consequences are not very pleasant (another understatement).
From my observations, applying a purely economic function to a natural system, sooner or later, does not work. It is very unfortunate that those making the decisions are ignorant or unwilling to look at other solutions that might work, and can also have a "win-win" outcome. Leaders (political, business, scientific, etc.) who's judgement is clouded with avariciousness in its various forms, or "be a winner (whatever dysfunction that is) or lose" thinking, create a great deal of suffering on this planet for many people and for many species.
