WHEN WILL WE REACH 8 BILLION PEOPLE?

Sorry for being a little late today.  I went to Shimazu Shave Ice and had a Ling Hing Mui flavored shave ice, topped with condensed cream...for $7.

Looking at the Worldometer data of yesterday, Japan remains #1 with 230,555 new cases.  The USA is #2 at 99,061.  The pandemic epicenter has shifted from Europe to Asia/Oceania.  Ranking of major countries in terms of new cases/million population:

  • #1  Japan  1831
  • #2  Australia  1733
  • #3  South Korea 1660
  • #4  New Zealand  1579
  • #6  Singapore  1335
  • #7  Taiwan  974
  • #8  Italy  909
  • #9  Austria  831
  • #10  Germany  783
The average for the U.S is 296 new cases/million.

Most think global warming is our biggest problem.  Over-population is also way up there as a concern.  According to the United Nations, the World will hit a population of 8 billion on November 15

  • The World reached 7 billion in 2011.
  • Our global population is growing at its slowest rate since 1950, increasing at a rate of less than one percent growth rate/year.
  • Fertility in two-thirds of the world is now below 2.1 births/woman, roughly a level for zero growth rate.  This was 4.5 in mid-70's.
  • The COVID-19 pandemic dropped global life expectancy at birth from 72.9 in 2019 to 71 last year.
  • But longevity is expected to rise to 77.2 in 2050.
  • More than half of the projected population increase will come from eight countries:  Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, Philippines and Tanzania.
  • By 2050, there will be twice the number of those 65 years and older than children under 5, and about the same as those up to 12 years old.
  • World Population day was July 11.  No one seemed to have cared.

World growth:

  • It took hundreds of thousands of years for the world to reach 1 billion in 1804.
    • Then by 10,000 BC, our population grew to somewhere between 1 and 15 million.
  • From 1 billion in 1804 it took 207 years to reach 7 billion.
  • Maybe 10 billion in 2058?
  • 2100?  Perhaps 11 billion.

What is the optimal population of Planet Earth?

  • In 1994 when the world population was 5.6 million, Paul Ehrlich and his colleages said 1.5 to 2 million.
  • Then in 2021 Sir Partha Dasgupta of Cambridge University said:  from half to 5 billion.  
  • In both cases, the matter of limited resources was why.  From Dasgupta:
Finally, humans versus others.
  • If a virus was the size of a 5 cent coin, a bacterium would be about the size of a dinner plate, and Danny Devito would be 656,168 feet tall.
  • Viruses  more than a quadrillion quadrillion.
    • About one nonillion, which is 1 followed by 30 zeroes.
    • Ten times more than all the bacteria.
  • Ants  perhaps 1 quadrillion, which is 1000 trillion or 1 million billion.
  • Cockroaches  up to 3 trillion.
  • Chickens  26 billion.
  • Humans  8 billion.
  • Cattle  1 billion.
  • Pigs  0.8 billion.
  • Blue whales, the largest creature ever--somewhere between 10,000 and 25,000.
  • Northern White Rhinos  2 (yes, two, both female)
Finally, there are 550 gigatons of carbon life in the world.  Of that humans are only 0.06 GTC.  All the bacteria are 1,166 times more massive.  Another way of looking at this is that humans make up just 1/10,000th of Earth's biomass.  We are virtually insignificant.

From National Geographic:

A dazzling, multicolored cuticle. A shiny chitinous armor. Photos taken with a microscope lens reveal the hypnotic beauty of the critters we usually dismiss as bugs. These colors come from chitin, a substance that forms an insect’s hard outer covering as well as its wings and other flexible parts. The chitin, which has been in arthropods for as long as 550 million years, is behind the metallic-colored scales of the Chrysiridia butterfly’s wings, or the thousands of lenses in a hornet’s compound eye.

You can have a ringtail cat as a pet.
