Human World Population

Between 10,000 BC and 2,000 AD

 

 

One important aspect of the "BE" concept is the exponential growth of the human world population and eventual decrease of human population when we are supposedly overshooting the carrying capacity. Here follows the global human population since 10,000 BC up to 2000 AD. "BE" also incorporates the estimated population up until 2050 AD. All these figures can be found in books and on the Internet. You can start by looking in the Sources.

10,000 BC 1 Million    
9,500 BC 2 Million    
9,000 BC 3 Million    
8,500 BC 4 Million    
8,000 BC 5 Million    
7,500 BC 5 Million    
7,000 BC 5 Million    
6,500 BC 5 Million    
6,000 BC 5 Million    
5,500 BC 5 Million    
5,000 BC 5 Million    
4,500 BC 6 Million    
4,000 BC 7 Million    
3,500 BC 10 Million    
3,000 BC 14 Million    
2,500 BC 20 Million    
2,000 BC 27 Million    
1,500 BC 38 Million    
1,000 BC 50 Million    
500 BC 100 Million    
Year 1 AD 170 Million    
500 AD 190 Million    
1000 AD 254 Million    
1500 AD 425 Million  
(less than half a Billion)
2000 AD 6,080 Million  
(more than 6 Billion!)

            

 

 


Parallels

(Overshooting the Carrying Capacity):

 

 

1910 - Reindeer population on St. Matthew Island, Alaska:

       1910: 4 male, 22 female deer

       1930: 250 deer

       1940: 2,000 deer

       1950: 8 deer left

 

14th century - Bubonic Plague:

More than 125 million people die in Europe during a few decades

 

 

Note: Exponential Growth (the old parable with the grains of corn doubling on the chess board is very describing for this mathematical term) is very impressive, but can never continue. At one point sooner or later it will be stopped one way or another. One way of reaching the limits of exponential growth in population is by overshooting the carrying capacity. The carrying capacity is defined as the maximum number of individuals that can be supported by the biotope in which they exist. Unfortunately we can never know for sure what the carrying capacity is for Earth when it comes to human beings (looking at what we have managed to do to the environment the last century one could easily come to the conclusion that weĠve already overshot the carrying capacity for our system). In the same way, we can never know when or how the exponential growth will be stopped, but as Carl Sagan says, if we do not stop it ourselves it will be stopped for us, most likely in a much less desirable fashion.
