By far the Earth’s biggest problem

By far the Earth’s biggest problem

The following info and more details can be viewed at:

“At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year.

A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987).”

  • During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.
  • In 1970, there were roughly half as many people in the world as there are now.
  • Because of declining growth rates, it will now take over 200 years to double again.

Expanding on the above: the 6th billion only took 11 years (1998), the 7th billion took 12 years (2010) and now, in 2018 we are at just over 7.6 billion. Even with the rate of increase decreasing the world is projected to exceed 10 billion by 2060.
