Each day, around the world, there are approximately

365,000 Births and 155,000 Deaths

 Notice that the number of births and deaths are not equal
   and that births greatly exceed deaths.

 

 

 

At current rates we add

210,000 additional people

each day.

 

 

 

This means that we add approximately

9,000 additional people

each hour.
.

 

 


The above numbers amount to approximately one
BILLION
additional persons added to our planet every twelve years
.


Between 1975 and 1987, we grew from a world population of four billion to a world population of five billion.     - twelve years -
.

Between 1987 and late 1999, we grew from a world population of five billion to a world population of six billion.     - twelve years -
.


and presently, we are headed higher still
.

                                              

 

The above data have greater meaning
if we appreciate how large a number a
BILLION really is.

 

                                                       

                                                       Consider this riddle:


How long would it take to complete
one
MILLION homework
questions at a rate of

100 questions per night,   five nights per week,
   52 weeks per year?
..

Answer:
38.5 years

 

 


Working at the same rate, how long would it take a student
to finish one
BILLION such questions?
..

Answer: 
To complete one billion such questions
would require

38,461
years.

 

 


If a student began working on this assignment
20,000 years ago

and completed 500 homework questions week after week
as each week passed from then until now,





he or she would have to

continue working for

another

18,461
years


into the future before

completing their billion question homework assignment
.

 

 

 

That is how many additional persons
we are adding to our planet

every twelve years

.

 

 

 

 


[ We should not be surprised if such enormous numbers
might place stresses on our societies, on our international relationships,
and on earth's enviornmental and ecological machinery.]
