                  seemingly “empty” environments?
THREE classicalreal-world examples of population calamities in

Real-world population-environment calamities, die-offs, and mass mortalities in „too-late‟ /
     „vast open-space‟ / „almost entirely empty‟ conditions as depicted in this image
Look at the tiny
      2/1000ths of 1% dot
         in this image




and imagine the most intelligent
      possible individuals
         residing there
Which, if any, members of
  such a population could be
convinced that their population
      faced a calamitous
   population-environment
     die-off and collapse



   when such vast amounts
  of „open-space ‟ appear to
 remain seemingly available?
We are covering this because
it has possible implications for us
The “Open-Space” Delusion
There is a widely-held misperception within much of society that
  human population growth and overpopulation cannot become
      truly serious so long as “vast amounts of open space”
             appear to remain theoretically-available
These seemingly innate
                                             or intuitive
                                           “open-space”
                                         suppositions can be
                                       exceptionally dangerous

                                      because they tempt us into
                                            complacency



     This presentation outlines THREE separate, classical,
and catastrophic real-world population outcomes (and die-offs)
          at tiny fractions of one percent thresholds
suppositions
                                                                                 assesses such




                                           mathematically
                                                                                This presentation


                                                            “vast open-space”




Supporting mathematics for the three classical examples
 that we use is outlined in the presentation‟s addenda
Imagine a real-world
                                         population of organisms
                                          surrounded by „vast
                         2/1000ths
                      of one percent     amounts of open-space‟

                                             in surroundings
 For the population in the above tiny
                                           that remain 99.998%
   white dot, the moment in time                unoccupied
depicted here was already “too-late”
                                           and which, visually-
                                        speaking, appears to remain

                                           almost entirely empty
Imagine, then, a population
                                whose combined bodies
                2/1000ths               (or cells)
             of one percent    physically-occupy an area
                                 equal to the tiny white
                                   dot in this image


                                  which constitutes
                              2/1000ths   of   one percent

                                        of the
                                   red rectangle in
                                   which it resides

Too-late conditions?
Notice that it would be
nearly impossible for even the
brightest scholars and leaders
     of such a population                         2/1000ths
                                               of one percent
to realize that the population-
   environment conditions
         depicted here

  are ALREADY “too-late”

And that at this point in time,
  both they and members
     of their population

      will have already
     waited TOO-LONG              Too-late conditions?
This presentation will review three classical real-world
   examples of population-environment calamities

 in environments that remain 99.998% unoccupied
and which appear to remain ALMOST ENTIRELY EMPTY
In all three classical examples, the populations involved
  experienced 99%-plus die-offs and/or other mass mortalities


   even as their combined bodies (or cells) physically-occupied
roughly 2/1000ths of one percent of the surroundings that appeared
             to remain theoretically-available to them
We will see that for all three examples
                               that we cover, the 2/1000ths of 1%
                                  conditions denoted by the tiny
                2/1000ths            white dot in this image
             of one percent


                                           already constitute
                                                too-late
                                               conditions,


                               and at the point in time depicted here, for
                                all three real-world populations it will
                                           already be too late,

                                      and they will have already
                                          waited too-long

5 – Exponential and Non-linear Growth in Population Systems
This presentation is about


 Climb-and-collapse outcomes in real-world
           population systems

 Population calamities in seemingly “vast
         open-space” environments

 Population explosions that induce calamity
         by their secretion of wastes

 U.N. human population projections to the
           end of this century

           and 2/1000ths of 1%
We are covering this because
it has possible implications for us
This presentation is also about             Climb-and-collapse

                                   Climb and collapse outcomes really happen
                                                and we are not immune

                                   Collapse routinely occurs in environments that
                                     visually appear to be almost entirely empty

                                   Collapse with 99% mortality is a biological reality

                                   We are not immune to collapse, and compared to
                                     any other animals or dinoflagellates that have
                                         ever lived, we are behaving very badly

                                   Three real-world examples of calamity in tiny
                                    fractions of 1% “vast open-space” conditions

                                   Plus , two classical real-world climb-and-collapse

                                                      We are covering this because it has possible implications for us
 Our release of wastes, which shows a disquieting
  similarity with population explosions of red-tide
  dinoflagellates

 Dinoflagellate red-tides as quintessential
  examples of population explosions that induce
        calamity by the release of wastes

 The fact that calamities can arise from wastes
             eradication, and damage

      (as opposed to “running-out-of” things)
This presentation is also about

 Our own trajectory which may well be far worse
  than outbreaks of dinoflagellate red-tide because
  we supplement our biological and metabolic
  wastes with a daily, and growing worldwide on-
  slaughts of industrial and societal wastes

 While outbreaks of dinoflagellate red-tide can be
  categorized as localized events, our own species
  exerts impacts that are global in extent

 Collapse routinely occurs in environments that
  visually-appear to be almost entirely empty

 Earth‟s atmosphere and seas as onion-skin-thin
            and superficial surface films

In two OTHER classical studies
                                       we will see that the organisms
                                        involved have also already

                                                  waited
                                                 too long

                                              TOO LATE
One-celled marine organisms
                     called dinoflagellates

                        constitute one of
                     nature‟s quintessential
                          examples of

                   population explosions that
                      induce calamity by

                        their production
   Red-tide                of wastes

                     killed an estimated
                                           along the coast of Texas
Other individual outbreaks have

     resulted in the deaths




                                       IN: NOAA‟s State of the Coast Report, Silver Spring, MD.
   of an estimated 150 tons
       of fish as well as

         manatees and
    other marine organisms
One species of dinoflagellate
known for such outbreaks is
      Karenia brevis
Real-world population explosions
of Karenia brevis manage to inflict
  such population disasters even as
their populations of 1,000,000 cells
     per liter physically-occupy


       less than 2/1000 ths
          of one percent



  of seemingly "vast amounts of
    open-space" that appear to
  remain theoretically available
Recall, then, the tiny
  white dot in this image


    which depicts in a
mathematically-correct way

    2/1000ths   of   1%

    of the rectangle in
     which it resides
In other words, the population-
explosions of dinoflagellates in
       red-tide outbreaks
            produce

   population-environment
         calamities

     in environments that




                                   Supporting mathematics is set forth in our appendices
  visually-appear to remain
Look again at the
      2/1000ths of 1% dot
         in this image




and imagine the most intelligent
      possible individuals
         residing there
Which, if any, members of
  such a population could be
convinced that their own species
      faced a calamitous
   environmental threshold



  when such vast amounts of
      open-space appear
to remain seemingly available?
In other words, they undergo
         and induce

  population-environment
        calamities

  by their production and
     release of wastes

   in environments that
   visually-appear to be


                            almost entirely empty
This set of conditions
  would seem to be
worth noting, perhaps,



                           since our own species
                             appears to exhibit


                         an extraordinarily similar
                            pattern of behavior
Unlike red-tide dinoflagellates,
  however, our own species
    does not confine itself

          to releasing

             only
     our biological and
  metabolic wastes into our
       surroundings
Instead, each day,
 on a worldwide basis, we
       supplement
   our biological wastes,


       in a way that is
       unprecedented
in the history of life on earth,


   with billions of tons of
societal and industrial wastes
so that we may be embarked upon a
      trajectory that is not only

             worse
           than that of
     red-tide dinoflagellates




                           but may be multiple orders of
                             magnitude worse, at that
This, of course, is not to necessarily
   suggest a direct applicability


   of dinoflagellate impacts and
            trajectories

      to humanity‟s own global
   trajectories and impacts today
However, the fact that dinoflagellate
                            populations can induce calamity

                                    by their production
                                   and release of wastes

                                   even when seemingly
                               “vast amounts of open-space”
                                      appear to remain
                                  theoretically-available


                              would seem to be worth noting

since our own species appears to exhibit an extraordinarily
                similar pattern of behavior
It is also worth noting that while
K. brevis cells release only their

    biological, cellular, and
       metabolic wastes
    into their surroundings,


         our own species
          supplements
its biological wastes with daily,
worldwide, and ever-increasing

    avalanches of industrial
      and societal wastes
No other animals do this,

          and

   no other animals in
      the history of
        the earth


have EVER done this
No other animals do this,

                                 and

                              the earth


                       have EVER done this




And we are doing so on a global scale in less
       than a single human lifetime
so that our own species
      may, perhaps,
   be on a trajectory
     that is not only

        Worse

than that of an outbreak
       of red-tide
    dinoflagellates,


             but may be multiple orders of magnitude
                         worse at that
Also, outbreaks of red-tide, while
    catastrophic, are at least
   relatively localized events




                     While our own population
                explosion, however, encompasses the
                       entire earth’s biosphere




                            as do the damages, wastes, impacts, and
                                   eradications that we inflict
But we are
      smarter



   than a population
of mindless one-celled
     dinoflagellates



     aren‟t we?
Of course we are smarter than dinoflagellates, aren‟t we?

     example, have not devised           waters and drain aquifers and

 Long-lines, radar, and GPS to
   catch entire schools of fish,          in less than a
                                                 single human lifetime

  power plants to pump green-
  house gases into the atmosphere

                                           Which means that we are
                                               smarter, right?
In other words, our ingenuity and technologies not only allow
     us to not only produce far more wastes more quickly
              than cells of red-tide dinoflagellates



       but they also allow us to multiply and amplify
            our individual and collective impacts,
                  damage, and eradications



          more quickly, completely, and efficiently
         than any other animals that have ever lived

All of which may not necessarily
qualify as especially “smart,” right?

More disquieting still, the real-world

Even the most intelligent, thoughtful,
 and educated members of a highly-
  intelligent species living in such
    “vast open-space” conditions



    would find it difficult (if not
       impossible) to imagine
         either the degree or
            the proximity
     of the too-late population-
     environment dangers and
              calamities

          that are about to
           overtake them

 when so much surrounding open-
space appears to remain seemingly-
            available
Yet, all three of the classical examples
used in this presentation, for instance,

   show quite powerfully that if the
 scholars and leaders of any of these
      three populations were to
                 WAIT

   until the conditions depicted in

    at this point, they would have

 types of graphs in the world)



  and since earth‟s

   capacity for a

 TWO billion or less
And since we are now
beyond seven billion and
 may be headed toward
10, 11, 12, 13, 14, or 15.8

Key Ideas so far




There is a widely-held misperception within our societies that
human population growth and overpopulation cannot be truly
       serious so long as “vast amounts of open space”
           appear to remain theoretically-available
Part two– Key Ideas




                                                                     Supporting mathematics is posted

 Real-world examples of Climb-and-collapse in population systems

 Collapse can and does occur in environments that appear to be
  almost entirely empty (.. less than 2/1000ths of one percent ..)

 Real-world examples of 99% - plus die-offs
 A graph of human population growth over the past two centuries
  appears to be both more pronounced and more extreme than those
  seen in either of the cited reindeer examples
Given the current demographic
   challenge that these numbers
             represent

  (and with up to our 10th to 15th
    billions on-track to arrive
    by the end of this century)



         One would hope that we are collectively smarter than
          a mindless population of one-celled dinoflagellates


that routinely show themselves
   capable of calamity while         less than 2/1000ths of 1% of the
           occupying                  volume in which the population
                                               sample resides
Invoking sobriety, however,
                                   we may actually be following
                                      a trajectory that has a
                                    worrisome similarity to that
                                      of the dinoflagellates




because our own species, like the red-tide dinoflagellates of marine
habitats, releases chemical wastes and toxins into our surroundings
Worse still, from at least one point of
                           view, however, we may actually be on a
                               trajectory that is worse than that
                                     of the dinoflagellates


                                    and multiple orders of
                                   magnitude worse at that




   for each dinoflagellate cell releases ONLY its
metabolic and biological wastes into its surroundings
In our own case, however, we
release not only our biological and
          metabolic wastes


  but also an unprecedented daily
avalanche of societal and industrial
     wastes that are worldwide
              in scope


       and amplified by our
      ever-growing numbers

1 Dinoflagellate red-tides are quintessential examples of population
  calamities arising from the release of wastes

2 Dinoflagellate red-tide calamities, however, arise from their release of
  cellular and metabolic wastes into their surroundings

3 Because our own species also releases wastes into its surroundings,
  we may be following a trajectory that is provocatively similar to that
  of an outbreak of dinoflagellate red-tide
Reviewing Several Key Ideas



    4 Except, of course, our own species supplements its biological and
      cellular wastes with a daily worldwide avalanche of industrial and
      societal wastes

    5 (A behavior that no other animals on earth exhibit – and has
            never previously happened in the entire history of the earth)

.   6 And lastly, while deadly outbreaks of dinoflagellate red-tide are
              localized events, our own population outbreak is a
             worldwide phenomenon and worldwide in its effects

   Concepts




         We are dangerously misled by our
        prevailing “open-space” suppositions
2/1000 ths of one percent




for it is a misperception to presume that human population growth and
  overpopulation cannot be truly serious so long as “vast amounts of
                           open space” remain

                                   Climb and collapse outcomes really happen
                                                and we are not immune

                                   Collapse routinely occurs in environments that
                                     visually appear to be almost entirely empty

                                   Collapse with 99% mortality is a biological reality

                                   We are not immune to collapse, and compared to
                                     any other animals or dinoflagellates that have
                                         ever lived, we are behaving very badly

 Our release of wastes, which shows a disquieting
  similarity with population explosions of red-tide
  dinoflagellates

 Dinoflagellate red-tides as quintessential
  examples of population explosions that induce
        calamity by the release of wastes

 The fact that calamities can arise from wastes
             eradication, and damage

      (as opposed to “running-out-of” things)
This presentation has also been about

 Our own trajectory which may well be far worse
  than outbreaks of dinoflagellate red-tide because
  we supplement our biological and metabolic
  wastes with a daily, and growing worldwide on-
  slaughts of industrial and societal wastes

 While outbreaks of dinoflagellate red-tide can be
  categorized as localized events, our own species
  exerts impacts that are global in extent

 Collapse routinely occurs in environments that
  visually-appear to be almost entirely empty

 Earth‟s atmosphere and seas as onion-skin-thin
            and superficial surface films
We are covering this because
it has possible implications for us
In addition, the “running-out-of” suppositions
that traditionally seem to govern our thinking


     such as “running-out-of” space, food,
        oil, resources, or anything else




       may not be the first or only factors
                that threaten us




               and such suppositions may lead us to an inaccurate
              assessment of our current status or impending danger
Finally, we are the only animals that
                                              do this, or that have ever done this


                                             and we are doing so on a worldwide
                                             scale so that we are not a localized
                                                        phenomenon


and our behaviors in this respects are not a minimal
or incidental footnote to the biology of our species

  but are instead one of our most distinguishing

which means that taken together, the peak population                               almost entirely empty.
Easter Island?
We assess Easter Island‟s historic climb-and-collapse human population data as outlined in Jared
Diamond‟s book, Collapse – How Societies Choose to Fail or Succeed (Viking, 2005) as follows:

Area of the island = approximately 170 km2 (about 66 square miles) or about 170,939,215 square meters.

Assuming a mid-range peak human population of approximately 15,000, and that the average individual in
the population physically-occupied approximately one square meter (standing), the combined area physic-
ally-occupied by all 15,000 individuals combined would equal approximately 15,000 square meters.

Therefore, given an island of approximately 170,939,215 square meters, if we subtract the approximately
15,000 square meters physically-occupied by all 15,000 human inhabitants combined, we are left with a
remainder of approximately 170,924,215 square meters of “unoccupied” “open-space” that would visually-
appear to remain seemingly-available.

Next, dividing the total “unoccupied” area (170,924,215 m2) by the island‟s total area of 170,939,212 m2,
equates to an island that is 0.999912 unoccupied, or 99.991% empty.

Thus we see that the mathematics suggests that a mid-range peak Easter Island human population reached
its peak and began its collapse even as “vast amounts of open-space” appeared to remain seemingly avail-
able and its inhabitants seemed to be living in an environment that was almost entirely empty.

Thus we see still another natural experiment that ended in collapse, this time involving a human society.
Note, however, that the similarity of our situation and that of the peak population of Easter Island is not
perfect, for the humans on Easter Island constituted a pre-industrial society that could kill its birds and

most of its seabirds, deforest its surroundings, and
overexploit its resources.

Our own numbers, however, are both far greater, and
our individual harmful impacts may have 50 or 100s
or even1000s of times the impact of a single pre-
industrialized individual.

Also unlike us, the island‟s pre-industrial society
was a localized society that could not generate
billions of tons of CO2 and industrial wastes, de-
grade and eradicate natural systems and plunder
resources from all parts of the planet.

In addition, they had no automobile exhausts, chlor-
ofluorocarbons, logging concessions, mechanized
fishing fleets, fossil fuels, nuclear and industrial
wastes, and investment portfolios with which to

Population calamities in seemingly empty environments 8 feb 2013a

  • 1. Real-world population calamities in seemingly “empty” environments?

  • 3. THREE classical real-world examples of population calamities in environments that remain 99.998% unoccupied 2/1000ths of 1% occupied Real-world population-environment calamities, die-offs, and mass mortalities in „too-late‟ / „vast open-space‟ / „almost entirely empty‟ conditions as depicted in this image
  • 4. Look at the tiny 2/1000ths of 1% dot in this image and imagine the most intelligent possible individuals residing there
  • 5. Which, if any, members of such a population could be convinced that their population faced a calamitous population-environment die-off and collapse when such vast amounts of „open-space ‟ appear to remain seemingly available?
  • 6. We are covering this because it has possible implications for us
  • 7. The “Open-Space” Delusion There is a widely-held misperception within much of society that human population growth and overpopulation cannot become truly serious so long as “vast amounts of open space” appear to remain theoretically-available
  • 8. These seemingly innate or intuitive “open-space” suppositions can be exceptionally dangerous because they tempt us into complacency This presentation outlines THREE separate, classical, and catastrophic real-world population outcomes (and die-offs) at tiny fractions of one percent thresholds
  • 9. suppositions assesses such mathematically This presentation “vast open-space” Supporting mathematics for the three classical examples that we use is outlined in the presentation‟s addenda
  • 10. Imagine a real-world population of organisms surrounded by „vast 2/1000ths of one percent amounts of open-space‟ in surroundings For the population in the above tiny that remain 99.998% white dot, the moment in time unoccupied depicted here was already “too-late” and which, visually- speaking, appears to remain almost entirely empty
  • 11. Imagine, then, a population whose combined bodies 2/1000ths (or cells) of one percent physically-occupy an area equal to the tiny white dot in this image which constitutes 2/1000ths of one percent of the red rectangle in which it resides Too-late conditions?
  • 12. Notice that it would be nearly impossible for even the brightest scholars and leaders of such a population 2/1000ths of one percent to realize that the population- environment conditions depicted here are ALREADY “too-late” And that at this point in time, both they and members of their population will have already waited TOO-LONG Too-late conditions?
  • 13. This presentation will review three classical real-world examples of population-environment calamities in environments that remain 99.998% unoccupied and which appear to remain ALMOST ENTIRELY EMPTY
  • 14. In all three classical examples, the populations involved experienced 99%-plus die-offs and/or other mass mortalities even as their combined bodies (or cells) physically-occupied roughly 2/1000ths of one percent of the surroundings that appeared to remain theoretically-available to them
  • 15. We will see that for all three examples that we cover, the 2/1000ths of 1% conditions denoted by the tiny 2/1000ths white dot in this image of one percent already constitute too-late conditions, and at the point in time depicted here, for all three real-world populations it will already be too late, and they will have already waited too-long Too-late conditions?

  • 22. This presentation is also about Climb-and-collapse  Climb and collapse outcomes really happen and we are not immune  Collapse routinely occurs in environments that visually appear to be almost entirely empty  Collapse with 99% mortality is a biological reality  We are not immune to collapse, and compared to any other animals or dinoflagellates that have ever lived, we are behaving very badly  Three real-world examples of calamity in tiny fractions of 1% “vast open-space” conditions  Plus , two classical real-world climb-and-collapse examples in separate mammalian populations

This presentation is also about  Our own trajectory which may well be far worse than outbreaks of dinoflagellate red-tide because we supplement our biological and metabolic wastes with a daily, and growing worldwide on- slaughts of industrial and societal wastes  While outbreaks of dinoflagellate red-tide can be categorized as localized events, our own species exerts impacts that are global in extent  Collapse routinely occurs in environments that visually-appear to be almost entirely empty  Earth‟s atmosphere and seas as onion-skin-thin and superficial surface films
  • 25. Population calamities in seemingly „empty‟ environments: Example one - Three Dinoflagellate red-tides classical real-world examples
  • 26. The dot in this image reflects one of nature‟s quintessential real-world population-environment calamities: an outbreak of Dinoflagellate red-tide The dot in this image denotes 2/1000ths of 1% of its rectangle
  • 27. In two OTHER classical studies we will see that the organisms involved have also already waited too long Supporting mathematics is posted in presentation appendices and have already passed a critical population-environment tipping-point so that the white dot in these images depicts conditions that are already TOO LATE
  • 28. One-celled marine organisms called dinoflagellates constitute one of nature‟s quintessential examples of population explosions that induce calamity by their production Red-tide of wastes Dinoflagellates
  • 29. Bushaw-Newton, K.L. and Sellner, K.G. 1999. Harmful Algal Blooms IN: NOAA‟s State of the Coast Report, Silver Spring, MD. red-tide in 1997-1998 dinoflagellate 21 million fish For example, a killed an estimated along the coast of Texas
  • 30. Other individual outbreaks have Bushaw-Newton, K.L. and Sellner, K.G. 1999. Harmful Algal Blooms resulted in the deaths IN: NOAA‟s State of the Coast Report, Silver Spring, MD. of an estimated 150 tons of fish as well as manatees and other marine organisms
  • 31. One species of dinoflagellate known for such outbreaks is Karenia brevis
  • 32. Real-world population explosions of Karenia brevis manage to inflict such population disasters even as their populations of 1,000,000 cells per liter physically-occupy less than 2/1000 ths of one percent of seemingly "vast amounts of open-space" that appear to remain theoretically available
  • 33. Recall, then, the tiny white dot in this image which depicts in a mathematically-correct way 2/1000ths of 1% of the rectangle in which it resides
  • 34. In other words, the population- explosions of dinoflagellates in red-tide outbreaks produce population-environment calamities in environments that Supporting mathematics is set forth in our appendices visually-appear to remain
  • 35. Look again at the 2/1000ths of 1% dot in this image and imagine the most intelligent possible individuals residing there
  • 36. Which, if any, members of such a population could be convinced that their own species faced a calamitous environmental threshold when such vast amounts of open-space appear to remain seemingly available?
  • 37. In other words, they undergo and induce population-environment calamities by their production and release of wastes in environments that visually-appear to be almost entirely empty
  • 38. This set of conditions would seem to be worth noting, perhaps, since our own species appears to exhibit an extraordinarily similar pattern of behavior
  • 39. Unlike red-tide dinoflagellates, however, our own species does not confine itself to releasing only our biological and metabolic wastes into our surroundings
  • 40. Instead, each day, on a worldwide basis, we supplement our biological wastes, in a way that is unprecedented in the history of life on earth, with billions of tons of societal and industrial wastes
  • 41. so that we may be embarked upon a trajectory that is not only worse than that of red-tide dinoflagellates but may be multiple orders of magnitude worse, at that
  • 42. This, of course, is not to necessarily suggest a direct applicability of dinoflagellate impacts and trajectories to humanity‟s own global trajectories and impacts today
  • 43. However, the fact that dinoflagellate populations can induce calamity by their production and release of wastes even when seemingly “vast amounts of open-space” appear to remain theoretically-available would seem to be worth noting since our own species appears to exhibit an extraordinarily similar pattern of behavior
  • 44. It is also worth noting that while K. brevis cells release only their biological, cellular, and metabolic wastes into their surroundings, our own species supplements its biological wastes with daily, worldwide, and ever-increasing avalanches of industrial and societal wastes
  • 45. No other animals do this, and no other animals in the history of the earth have EVER done this
  • 46. No other animals do this, and no other animals in the history of the earth have EVER done this And we are doing so on a global scale in less than a single human lifetime
  • 47. so that our own species may, perhaps, be on a trajectory that is not only Worse than that of an outbreak of red-tide dinoflagellates, but may be multiple orders of magnitude worse at that
  • 48. Also, outbreaks of red-tide, while catastrophic, are at least relatively localized events While our own population explosion, however, encompasses the entire earth’s biosphere as do the damages, wastes, impacts, and eradications that we inflict
  • 49. But we are smarter than a population of mindless one-celled dinoflagellates aren‟t we?
  • 50. Of course we are smarter than dinoflagellates, aren‟t we? Dinoflagellates, for  Nor ways to pollute earth‟s example, have not devised waters and drain aquifers and eradicate water bodies like the  Bulldozers, chain saws, tools, Aral Sea and machines to quickly eradicate entire forests, throughout the entire world all at the same time  Long-lines, radar, and GPS to catch entire schools of fish, in less than a single human lifetime  Automobiles, coal mines, and power plants to pump green- house gases into the atmosphere

  • 52. In other words, our ingenuity and technologies not only allow us to not only produce far more wastes more quickly than cells of red-tide dinoflagellates but they also allow us to multiply and amplify our individual and collective impacts, damage, and eradications more quickly, completely, and efficiently than any other animals that have ever lived

  • 57. Two classical examples Real-world Climb-and-collapse Supporting mathematics is posted in appendices ONE and TWO
  • 58. We are covering this because it has possible implications for us
  • 59. Scheffer, V.B., 1951. The rise and fall of a reindeer herd, Scientific Monthly 73:356-362 Scheffer, 1951 population studies of reindeer herds First, note these two classic Climb-and-collapse Klein, 1968 Klein, D.R., 1968. The Introduction, Increase, and Crash of Reindeer on St. Matthew Island. Journal of Wildlife Management 32: 350-367.
  • 60. Notice that each reindeer herd exhibited a classic Supporting mathematics is posted in appendices ONE and TWO Climb-and-collapse population curve Scheffer, 1951 Klein, 1968
  • 61. In each case, an initial period of exponential growth was followed by a Supporting mathematics is posted in appendices ONE and TWO 99%-plus die-off Scheffer, 1951 Klein, 1968
  • 62. Secondly we note that each reindeer population physically-occupied Supporting mathematics is posted in appendices ONE and TWO roughly 2/1000ths of 1% of surroundings that, visually-speaking, appeared to remain theoretically-available to them at the time of the collapse
  • 63. So that both classical die-offs BEGAN (and proceeded) in environments that visually appeared to remain Supporting mathematics is posted in appendices ONE and TWO almost entirely empty
  • 64. Supporting mathematics is posted in appendices ONE and TWO approximately 99.998% EMPTY
  • 65. So that both classic die-offs BEGAN (and proceeded) in environments that visually appeared to remain almost entirely empty
  • 66. Compare these two graphs Below: Note the reindeer rocketing upward before their 99% die-off Right: Human population growth 8000 BC to present (and now rocketing upward?)
  • 67. Compare these two graphs Which upward trajectory is more pronounced and more extreme? Do you see any disquieting similarities?
  • 68. More disquieting still, the real-world numbers that actually emerge could turn out to be very much larger than the medium- fertility U.N. estimates
  • 69. If worldwide fertility levels Billions 7, 8, 9, 10, 11, 12, 13, 14, and 15 are based average just on U.N. high- fertility projections to 2100 ½ child per woman higher than the U.N.‟s medium- fertility projections, we will find ourselves on-track toward 15.8 billion by 2100
  • 70. Even the most intelligent, thoughtful, and educated members of a highly- intelligent species living in such “vast open-space” conditions would find it difficult (if not impossible) to imagine either the degree or the proximity of the too-late population- environment dangers and calamities that are about to overtake them when so much surrounding open- space appears to remain seemingly- available
  • 71. Yet, all three of the classical examples used in this presentation, for instance, show quite powerfully that if the scholars and leaders of any of these three populations were to WAIT until the conditions depicted in the image shown here develop at this point, they would have already waited Too-long
  • 72. In 1911 in the V. B. Scheffer study, 25 reindeer were introduced to 41 square mile St. Paul Island, Alaska Scheffer, 1951 by 1938, their population peaked at more than 2000 reindeer – yet by 1950 only eight remained
  • 73. At their peak population of more than 2000 reindeer (shown here) their combined bodies physically-occupied roughly 2/1000ths of 1% of the island upon which they lived
  • 74. And then they underwent a 99% - plus die-off Scheffer, V.B., 1951. The rise and fall of a reindeer even as, taken together, their herd, Scientific Monthly 73:356-362 combined bodies physically- occupied only a tiny Scheffer, 1951 fraction of one percent of their seemingly-available environment
  • 75. In 1944, 29 reindeer were introduced to 128 square mile St. Matthew Island, Alaska Klein, 1968 by 1963, their population peaked at more than 6000 reindeer and fell to 42 remaining in 1964
  • 76. At their peak population of more than 6000 reindeer (shown here) their combined bodies physically-occupied about 2/1000ths of 1% of the island upon which they lived Klein, 1968
  • 77. And then they underwent a 99% - plus die-off even as, taken together, their combined bodies physically- occupied only a tiny fraction of one percent Klein, 1968 of their seemingly-available environment
  • 78. Notice therefore that both herds underwent a 99% - plus die-off
  • 79. even as their combined bodies physically-occupied a tiny fraction of one percent of the “vast quantities of open- space” that seemed to remain roughly 2/1000ths of 1% theoretically-available
  • 80. In nature, this really does happen, and this presentation cites actual examples in four entirely independent settings  Twice in reindeer herds (mammals), AND  In outbreaks of red-tide in unicellular marine organisms, AND  Apparently to the early human inhabitants of Easter Island (which we include in our appendices)
  • 81. End of part two
  • 83. Also disquieting, the real-world worldwide human population numbers that actually emerge could turn out to be very much larger than the medium-fertility U.N. estimates shown here

Six-fold life-extensions have already been Unexpected advances in would result in healthy, active 500-year-olds achieved in laboratory organisms And an equivalent extension in humans life-extension or unexpected declines in mortality or if worldwide fertility levels stall or turn out to be just ½ child per woman higher than the U.N.‟s “medium-fertility” estimates
  • 85. 15.8 billion headed toward (as shown in this graph) We could find ourselves by the end of this century Even tiny fractional such extensions in humans would toss current U.N. population projections right out the window
  • 86. Notice that these graphs are quintessential examples of J-curves (one of the most dangerous types of graphs in the world) and since earth‟s planetary carrying capacity for a modern industrialized humanity is on the order of TWO billion or less
  • 87. And since we are now beyond seven billion and may be headed toward 10, 11, 12, 13, 14, or 15.8 billion this century and since each one of our billions is a truly enormous number (see appendix)
  • 88. Policymakers, academia, and the world‟s rising generations of „Under-20s‟ should accord emergency-scale attention to these numbers
  • 89. Key Ideas so far There is a widely-held misperception within our societies that human population growth and overpopulation cannot be truly serious so long as “vast amounts of open space” appear to remain theoretically-available
  • 90. Part two– Key Ideas Supporting mathematics is posted in appendices ONE AND TWO  Real-world examples of Climb-and-collapse in population systems  Collapse can and does occur in environments that appear to be almost entirely empty (.. less than 2/1000ths of one percent ..)  Real-world examples of 99% - plus die-offs  A graph of human population growth over the past two centuries appears to be both more pronounced and more extreme than those seen in either of the cited reindeer examples
  • 91. Given the current demographic challenge that these numbers represent (and with up to our 10th to 15th billions on-track to arrive by the end of this century) One would hope that we are collectively smarter than a mindless population of one-celled dinoflagellates that routinely show themselves capable of calamity while less than 2/1000ths of 1% of the occupying volume in which the population sample resides
  • 92. Invoking sobriety, however, we may actually be following a trajectory that has a worrisome similarity to that of the dinoflagellates because our own species, like the red-tide dinoflagellates of marine habitats, releases chemical wastes and toxins into our surroundings
  • 93. Worse still, from at least one point of view, however, we may actually be on a trajectory that is worse than that of the dinoflagellates and multiple orders of magnitude worse at that for each dinoflagellate cell releases ONLY its metabolic and biological wastes into its surroundings
  • 94. In our own case, however, we release not only our biological and metabolic wastes but also an unprecedented daily avalanche of societal and industrial wastes that are worldwide in scope and amplified by our ever-growing numbers and increasing industrialization
  • 95. Reviewing Several Key Ideas 1 Dinoflagellate red-tides are quintessential examples of population calamities arising from the release of wastes 2 Dinoflagellate red-tide calamities, however, arise from their release of cellular and metabolic wastes into their surroundings 3 Because our own species also releases wastes into its surroundings, we may be following a trajectory that is provocatively similar to that of an outbreak of dinoflagellate red-tide
  • 96. Reviewing Several Key Ideas 4 Except, of course, our own species supplements its biological and cellular wastes with a daily worldwide avalanche of industrial and societal wastes 5 (A behavior that no other animals on earth exhibit – and has never previously happened in the entire history of the earth) . 6 And lastly, while deadly outbreaks of dinoflagellate red-tide are localized events, our own population outbreak is a worldwide phenomenon and worldwide in its effects
  • 97. Part Four No other animals do this

  • 99. Photos courtesy of life.nbii.gov: fox = Mosesso; Others - Hermann In virtually all of these cases, each organism‟s daily pollution of its environment is limited to daily production of its bodily wastes
  • 100. No population explosions of red-tide dinoflagellates (which poison their environments by the wastes that they release) have EVER supplemented their cellular and biological wastes with a daily worldwide avalanche of industrial and societal wastes the way that we do
  • 101. No other animal species supplements its cellular and biological wastes with a planet-wide and ever- increasing avalanche of industrial and societal wastes the way that we do
  • 102. And then there are also the enormous additional levels of eradication, degradation and sheer levels of PHYSICAL DAMAGE that we are inflicting everywhere upon the ONLY planetary life-support machinery so far known to exist anywhere in the universe
  • 103. No other organisms in the entire history of the earth have EVER supplemented their cellular and biological wastes the way that we do
  • 104. And these behaviors are NOT a minimal or incidental footnote to the biology of our species
  • 105. Instead, they are one of our most distinctive and all-encompassing characteristics
  • 106. Summaries and Key Concepts We are dangerously misled by our prevailing “open-space” suppositions
  • 107. 2/1000 ths of one percent for it is a misperception to presume that human population growth and overpopulation cannot be truly serious so long as “vast amounts of open space” remain
  • 108. This presentation has also been about Climb-and-collapse  Climb and collapse outcomes really happen and we are not immune  Collapse routinely occurs in environments that visually appear to be almost entirely empty  Collapse with 99% mortality is a biological reality  We are not immune to collapse, and compared to any other animals or dinoflagellates that have ever lived, we are behaving very badly  Three real-world examples of calamity in tiny fractions of 1% “vast open-space” conditions  Plus , two classical real-world climb-and-collapse examples in separate mammalian populations
  • 109. This presentation has also been about We are covering this because it has possible implications for us  Our release of wastes, which shows a disquieting similarity with population explosions of red-tide dinoflagellates  Dinoflagellate red-tides as quintessential examples of population explosions that induce calamity by the release of wastes  The fact that calamities can arise from wastes eradication, and damage (as opposed to “running-out-of” things)
  • 110. This presentation has also been about  Our own trajectory which may well be far worse than outbreaks of dinoflagellate red-tide because we supplement our biological and metabolic wastes with a daily, and growing worldwide on- slaughts of industrial and societal wastes  While outbreaks of dinoflagellate red-tide can be categorized as localized events, our own species exerts impacts that are global in extent  Collapse routinely occurs in environments that visually-appear to be almost entirely empty  Earth‟s atmosphere and seas as onion-skin-thin and superficial surface films
  • 111. We are covering this because it has possible implications for us
  • 112. In addition, the “running-out-of” suppositions that traditionally seem to govern our thinking such as “running-out-of” space, food, oil, resources, or anything else may not be the first or only factors that threaten us and such suppositions may lead us to an inaccurate assessment of our current status or impending danger
  • 113. Finally, we are the only animals that do this, or that have ever done this and we are doing so on a worldwide scale so that we are not a localized phenomenon and our behaviors in this respects are not a minimal or incidental footnote to the biology of our species but are instead one of our most distinguishing and all-encompassing characteristics
  • 114. Lastly, but not least, there are these two graphs of our demographics which are very much like J-curves on steroids
  • 115. First, five additional billions in less than one human lifetime since 1930 with the potential arrivals of billions numbers 10, 11, 12, 13, 14, and 15 (and 800 million more after that) due by the end of this century on a planet whose biospheric machinery was already being damaged at levels of five billion and six billion in 1987 and 1999 and whose planetary carrying capacity for a modern, industrialized humanity is on the order of two billion or less

  • 122. Easter Island? We assess Easter Island‟s historic climb-and-collapse human population data as outlined in Jared Diamond‟s book, Collapse – How Societies Choose to Fail or Succeed (Viking, 2005) as follows: Area of the island = approximately 170 km2 (about 66 square miles) or about 170,939,215 square meters. Assuming a mid-range peak human population of approximately 15,000, and that the average individual in the population physically-occupied approximately one square meter (standing), the combined area physic- ally-occupied by all 15,000 individuals combined would equal approximately 15,000 square meters. Therefore, given an island of approximately 170,939,215 square meters, if we subtract the approximately 15,000 square meters physically-occupied by all 15,000 human inhabitants combined, we are left with a remainder of approximately 170,924,215 square meters of “unoccupied” “open-space” that would visually- appear to remain seemingly-available. Next, dividing the total “unoccupied” area (170,924,215 m2) by the island‟s total area of 170,939,212 m2, equates to an island that is 0.999912 unoccupied, or 99.991% empty. Thus we see that the mathematics suggests that a mid-range peak Easter Island human population reached its peak and began its collapse even as “vast amounts of open-space” appeared to remain seemingly avail- able and its inhabitants seemed to be living in an environment that was almost entirely empty. Thus we see still another natural experiment that ended in collapse, this time involving a human society. Note, however, that the similarity of our situation and that of the peak population of Easter Island is not perfect, for the humans on Easter Island constituted a pre-industrial society that could kill its birds and

Our own numbers, however, are both far greater, and our individual harmful impacts may have 50 or 100s or even1000s of times the impact of a single pre- industrialized individual. Also unlike us, the island‟s pre-industrial society was a localized society that could not generate billions of tons of CO2 and industrial wastes, de- grade and eradicate natural systems and plunder resources from all parts of the planet. In addition, they had no automobile exhausts, chlor- ofluorocarbons, logging concessions, mechanized fishing fleets, fossil fuels, nuclear and industrial wastes, and investment portfolios with which to simultaneously assault every corner of our planet.
