Because first of all, only 1 billion people are sustainable on the surface of earth (unless everyone lives underground to begin with) in terms of humans living here thousands of years more.
So, that's a given to begin with. But, then as an intuitive I realized that humans would be hard put to survive Global Warming and Global Climate change with most Ocean coastal cities going underwater this century all over the globe. Take out a map and look at the elevations of most coastal cities on earth and you will see what I mean. Miami for example, goes under water in some sections every king tide at high tide or even more frequently.
So, houses and buildings underwater at least up to the 1st floor on multi-story buildings is expected in cities all around the world on the ocean at this point by 2100.
But, I didn't expect that a pandemic would do this even though I knew it was possible. Then when you combine coronavirus and fires or hurricanes or tornadoes or droughts or other natural calamities like Earthquakes the combination is going to kill a whole lot of people worldwide and mostly there is nothing to be done about it worldwide unless nations have enough access to technology and the technology to bring them enough food through all this to survive it
So, because of all this it is likely that the population of earth in 2100 will be somewhere between 1 billion people and 4 billion people depending upon how all this is handled during this century.
Big wars won't happen because of nuclear weapons so global Warming and pandemics likely will thin out the human race down to 1 to 4 billion by 2100.
If you take every country on earth and half their present populations this would be what 4 billion people looks like in 2100 AD
IF you want to see what 1 billion people left on earth looks like divide each countries population by 8 to see what that would be.
For example, 1/8 of China's present population would be 175 million people
For the U.S. 41, 025,000
For India 169,125,000
Check your country if you are interested in doing the math.
As an intuitive whether it is closer to 4 billion or 1 billion will depend upon all the people of the world and all it's leaders between now and 2100.
The Closest I could come to 41,025,000 was with the 1880 census for the U.S. which was:
50,189,209 |
In other words the future we create this century is up to all of us.
By God's Grace
