Click pdf 1 for Population Growth and
                   The Open-space Delusion
(Population, climate, and CO2; and
                           "No other animals do this...") 

Click pdf 2 for Numerics and the Riddle of 
                  a "Billion Homework Questions"
(Hint:  The answer is 38,461 years;  and our 7th, 8th
             and 9th billions are on-track to arrive by 2050 )

Click pdf 3 for    Razor-Thin Films:
                 Earth's Atmosphere and Seas
(Our suppositions of immensity are an illusion; plus our
    impacts on climate -"No other animals do this...")

Click pdf 4 for   Why Conservation Goals 
                          Of 10% are Not Enough 
(Conservation goals that once envisioned saving species
and representative samplings of habitat are almost certainly
insufficient to conserve ecosystem function.  And at some
point during the 90% eradication that current 10% policies
envision and may permit, an inevitable tipping point will
almost certainly be crossed leading to eventual collapse of
the remnants themselves.)

Click pdf 5 for    A Critique of
                                          Beyond Six Billion 
(Bongaarts and Bulatao, eds., National Academy Press)

Click pdf 6 for   One-hundred Key Objectives
                        and Biospheric Understandings
(Carrying capacity, limiting factors, tipping points, births,
 deaths, net increase, thresholds, fertility, feedbacks, etc.) 

Click pdf 7 for   Carrying Capacity
                                         and Limiting Factors
(Wastes, disease, hunger, aggression, adreno-pituitary,
  hormonal;  earth's limited capacity to cleanse, recycle,
  absorb, or otherwise accommodate our societal and in-
  dustrial wastes)

Click pdf 8 for   Thresholds, Tipping Points,
                       and Unintended Consequences
(We are living at a time when each of humanity’s added
billions is impacting one natural system after another, in-
crementally, and in most cases, repeatedly – again, and
again, and again.  And some of these many impacts may
transgress critical thresholds or tipping points or result
in unintended and possibly irreversible consequences.)

Click pdf 9 for   Humanity's Demographic
(World population levels over the past ten millennia with
 modern milestones in 1830, 1930, 1960, 1975, 1987, 1999,
 and the four decades that lie just ahead.)
