I’am afraid about the world population growth. Modern medicine and agriculture have given exponential growth in world population, in bacterial numbers like billions. History solved overpopulation
with wars, famine or diseases. Pushing world natural resources beyond it’s limits and an continuous human population growth is a reciepe for future horrible events.
Either the world might become unhabitable by overuse or a large part of the worlds population might suffer horrible future events. If the price of a unhabitable earth becomes to large and a probability for such event becomes too high, then I will be afraid. By not supporting and trying to stop an unsustainable human world population growth, people might indirect be responsible for future horrible events that affects a large part of world population, or the whole world and all population ceases to exist.
If there are calculations for future scenarious that includes creating for example an viruses to reduce world population, I would not be surprised if such calculations exist behind close doors. It might only be loigcal as having caculations on how to respond on future scenarious like global nuclear weapon attacks.
The possibility of such scenarious is another question, it might be 0.001% or 50%, I don’t know.
But let’s play with a scenario in a fictional way:
If the probability of the whole world goes up in flames and all population ceases to exist and if that could be countered with, let’s say a fictional number of 30% world population reduction, then the calculation would look something like this.
critical probability of the world goes up in flames * world population = 1/3 of world population
1/3 of world population / world population = critical probability of the world goes up in flames
2.8 / 7.6 = 0,368 = 36.8%
Concllusion : If an world ending event have a 36.8% or higher probability, and that event could be solved by in a fictional scenario reduce world population by 1/3, then it would be logical correct to act on such solution.
This wouild be similar calculations that goes on behind closed doors for a number of future events like example nuclear wars and similar, there are also other complicated game theories in play. My numbers calculation might be wrong, I have not done such in a while, but others will for sure correct them if they are wrong.
