Arguably, the two graphs below may depict
in the history of our species

Human Population Growth - 8000 B.C. to 2100 A.D.

Notice that beginning with a worldwide population of two billion in 1930,
 we reached seven billion late in 2011.

Five additional billions in a single human lifetime

 and we are on-track to add still more billions
(numbers eight and nine) by 2041,
and U.N. medium-fertility models project more
than 10 billion by the close of this century...

Notice that our data sets show that virtually all
of our growth has occurred since 1800 and

we are currently adding an additional billion
to our numbers every twelve to fifteen years.


And the real-world numbers that could emerge may actually be VERY much higher,

15.8 Billion by 2100? - And notice the J-curve

for if worldwide fertility rates average just 1/2 child per woman higher than the U.N.'s "medium-fertility" projections, we will find ourselves on-track toward 15.8 BILLION by 2100 (these latter numbers are depicted in the graph shown left)

Notice that both graphs depicted above are quite-pronounced J-curves
Thus, despite an unwarranted complacency among many, humanity's central problems today include, among other things, (a) the impending arrival of our 7th, 8th, and 9th billions by 2041, as well billion number 10 (and/or 11, 12, 13, 14, and/or 15.8 by the end of this century, along with (b) the extreme levels of overpopulation and environmental impacts that we already exhibit.

As a result, a continuation of today's demographic tidal wave may
the greatest single risk that our species has ever undertaken

Scientists, students, mathematicians, educators, other scholars,
and policymakers might note that the both graphs on this page
suggest that we may well be living through

the closing phases of an exponential progression
It might also be noted that the graph below bears a striking similarity to
a graph of the fission events that took place inside the nuclear
detonation that destroyed Hiroshima, Japan at the close of World War II



Each day there are approximately 380,683 births that take place somewhere around the world.   During the same twenty-four hours, there are approximately 153,653 deaths

Which means that despite a prevailing sense of complacency seen in some economic and political circles, world population now grows larger by approximately 227,000 extra persons per day

(After World Population Data Sheet 2009,
Populatiion Reference Bureau).




Sample implications?

If today is Friday, by this same time on Monday, earth will
be home to more than
681,000 additional persons.
(Hopefully, someone, somewhere, is planning to
grow a lot of extra food over the weekend.)




If today is Monday, by this same time
on Friday, earth will be home to more
than  908,000  additional persons.
At this rate of new arrivals, society must complete more
36,320 additional classrooms
every four days
with, presumably, a price to
be paid if they are not built.

There exists a specific repertoire of information that every citizen should know about our planet which Wecskaop's chapters present and key components of which are sampled on this website and itemized in its appendices.
Today we operate our societies on the presumption that the functioning of natural systems is a given.  Such assumptions are no longer warranted under current conditions of population growth.
