World Population Day

       I recently read a statistic that I could hardly believe.  Every day, the world’s population increases by 227,000 people!  

     227,000!  That’s like adding a mid-sized city every single day.  And this 227,000 figure is not the number of births each day;  it’s the number of births minus the number of deaths, or the net increase.  

     I am thinking about world population because tomorrow, Friday, July 11, is World Population Day.  This annual observance was established by the United Nations in 1989 as a vehicle to build awareness of population issues and the impact they have on the environment and on development.  The United Nations Population Fund encourages governments, non-governmental organizations, institutions, and individuals to organize educational activities to mark the annual event.

     Why July 11?  That was the day in, 1987, when the global human population first reached five billion.  The Day of Five Billion attracted so much interest all around the world that the UN and population educators joined together to create an annual occasion to focus the world’s attention on the challenges posed by population growth.

Global population growth is truly a fascinating phenomenon.  Long, long ago, when humans lived in bands of hunters and gatherers, the population was small and stable.  Then, with the advent of agriculture about 10,000 years ago, more food became available and the human population began to grow.  Then came the Industrial Revolution in the 1700s.  With expanded agriculture and life-saving medical advances, the human population started to increase exponentially.

Consider the following:

  • About 8,000 BC when farming began, the global population was about 5 million.
  • By about 1 AD, 8,000 years later, the population was about 200 million.
  • About 1800 years later, by 1800 AD, the human population reached its first billion.
  • By 1930, just 130 years later, the population crossed the 2 billion mark.
  • By 1959, a mere 29 years later, the population had grown to 3 billion.
  • By 1974, only 15 years later, the world population reached 4 billion.
  • In 1987, 13 years later, there were 5 billion of us.
  • The 20th century began with 1.6 billion people and ended with 6.1 billion.  
  • Most of the population growth throughout history took place in a single century!
  • Today, the global population is 7.2 billion.  

Population growth rates are falling throughout the world.  But because of rapid population increases in past decades, the number of people in their childbearing years is very high.  Thus, even with a low birth rate, the actual number of people will continue to grow for several decades.  Demographers call this phenomenon ‘demographic momentum.’

Demographers predict that population could grow to 9 billion by 2050 and then stabilize.–April Moore

    We think our numbers are of some concern, but humans are not as significant as we are influenced to believe. There are 10 billion billion ants, 18.6 billion domestic chickens, and at any given place in New York city, one is only a few feet away from a rat and that was in 2009. There are 350 million tons of humans and 500 million tons of cattle. The earth upon which all of this and other masses frequent is, 13,169,533,693,875,800,921,604,096 pounds. Humans are not even felt by the Mother.
