   4. What Could Intervene?

 1. Famine due to Global Warming
       --- Can we feed 8 billion people?
       --- Many say no. Water shortage.
       --- Drought-induced famine.
            Climate-change-induced drought.
            Runaway hydrocarbons

 2. Disease Pandemic
       --- SARS, MERS, a new bird flu,
         Ebola, coronavirus?

 3. Nuclear Winter
       --- Nuclear war, comet, asteroid,
       --- 
Super volcano (Yellowstone?)

 4. The Earth's Poles Flip
       --- Geomagnetic Reversal
       --- Calamity for our electronics
       --- Happened thousands of times before
       --- About every 100K years - overdue.

 5. The Apocalypse (religion induced)
       --- People lose their minds on massive scale
       --- Showman Trump becomes dictator-king
       --- Trump starts nuke war, to boost his ego
       --- Its all over (see #3).

 6. ET Intervention
       --- Repurposing the planet -
Zoo Hypothesis

 7. God Gets Bored
       --- Perceives pointlessness, decides to end it
       --- After all, it has been billions of years

Are these 7 scenarios listed by likelihood?
Posssibly. Very hard to say. Take a guess.
Is your guess better than mine?

Based upon varying probabilities, and geologic time scales, ANY ONE could leap to the top at ANY TIME.
Think about that. Then, quietly go crazy.

The Population Bomb"
     written by Paul Ehrlich in 1968 (Stanford U.).

Disclaimer:
Source: US Department of Commerce, plus other research.
There are many estimates of population for various time periods.
The reporting categories change over time, introducing discrepancies that must be resolved.
I have selected the numbers which are the most consistent among experts in the demographics field.
This ain't easy - you try it.
It is a collection of best guesses.
