Each day there are approximately births During the same 24 hours, there are approximately deaths

5
Notice that there are approximately birthseach day 356 000 minus 154 000 equals 202 000
6
persons inhabiting our planet each hour Notice that this amounts to approximately
7
persons to our planet every twelve to fifteen years At these rates of growth, we add approximately
8
as simply very large numbers It is easy to think of a and a
9
different But in reality, they are
10
homework questions at a rate of How long would it take to complete one 100 questions per night, five nights per week 52 weeks per year
11
to finish such an assignment Answer: It would take
12
homework questions How long would it take to complete one working at the same rate?
13
To complete one billion such questions would require Answer:
14
This means that if a student began working on this assignment years ago
15
When ice was one mile thick over and
16
When and still roamed the earth
17
And each and every homework question was conscientiously completed years from then until now for all
18
The student would have to CONTINUE working on their homework years into the future for ANOTHER in order to finish their assignment
19
That is how many people we are adding to our planet every twelve to fifteen years
20
No wonder earth’s environmental and biological machinery is breaking
21
Notice that a billion is an number
22
We should not be surprised if such enormous numbers have potentially-disastrous humanitarian, civilizational, and biospheric implications
23
While our population would remain stable if births and deaths were equal At today’s rates, we add additional people to our planet every twelve to fifteen years
24
Food Health care Housing Roads Education Employment
25
Sanitation Drinking water and a host of Other necessities And this is without yet raising the issues of all the environmental damage that we inflict
26
by this same time on Monday Earth will be home to For example, additional people
27
Hopefully, someone, somewhere is planning to grow a LOT of extra food over the weekend
28
by this same time on Friday Earth will be home to Similarly, additional people
29
Necessitating completion of more than additional classrooms by this same time on Friday Math footnote: Assuming that all “replacement” children can be accommodated by existing classrooms, then 800,000 additional children divided by 25 students per classroom necessitates completion of more than 32,000 additional classrooms by this same time on Friday.

What if not enough jobs are available? What if not enough schools and classrooms are built? What if no electricity and firewood are available? What if young men ages 15 – 30 have little schooling, no skills, and no jobs?
31
It took about one-hundred years (1850 to 1950) for the populations of the United States and Europe to approximately double Today, the populations of many of the world’s poorest countries have been doubling every three decades or less
32
Even a rich country would find it nearly impossible to repeatedly double all of its schools, services, health care, and infrastructure in repeated spans of two or three decades and some have QUADRUPLED in less than fifty years If the world’s poorest nations were working with stable populations, their chances of improving standards of living would be greatly enhanced
33
Recall that a billion is a very, very large number
34
Notice that it took ALL of human history until 1930 for us to reach
35
And now, just since 1930 we have added additional persons to our planet in less than one human lifetime
36
1930 – 1960: Two billion grew to three billion 1960 – 1975: Three billion grew to four billion 1975 – 1987: Four billion grew to five billion 1987 – 1999: Five billion grew to six billion
37
And our 7 th 8 th and 9 th billions are all on-track to arrive between now and mid-century
38
No human beings in history have ever lived through such a demographic onslaught
39
Throughout history, we have always been able to count on the functioning of earth’s natural systems as a given Today, however, our population has already become so large, and continues to grow larger so rapidly that such PRESUMPTIONS are no longer warranted
40
A continuation of today’s demographic tidal wave may constitute the greatest single risk that our species has ever undertaken
