To make full sense of this it must be recognized that I am speaking as a life long intuitive. And as such I can give you a self diagnoses that what I am saying is at least 80% to 90% accuracy. And because of this level of accuracy presently present I am writing about this.
There are several ways in which the human race will survive the next 1000 plus years. And here are the basic ways.
I will start with the least desirable way and work up to the most desirable.
The least desirable way is:
World Civilization Collapse
In this scenario the various civilizations of earth become incapable of living together peacefully ongoing and the end result is that only about 100 to 300 million people remain worldwide. Within 200 to 500 years all electrical technology and most mechanical technology is lot and life returns at best to pre 500 AD life with many less people. Then over several thousand years life returns to where we are today and then the human race on earth will decide whether to Collapse again or to progress forward as a planetary civilization with diversity of philosophy and religions present within a relatively peaceful context.
The next level up so to speak would be:
Partial World Civilization Collapse
In this scenario most civilizations collapse through war, disease etc. The remaining civilization has lost most technology and so if no further wars develop that civilization helps the world return to its present level or thereabouts.
The next scenario is the most likely that we will have to endure.
Overpopulation: creates starvation which creates many small wars ongoing
In this scenario which is the present de facto world in which we live in we will
see cascading wars caused by the desperation of basic human survival for about 1/2 the world's population leading to more and more garish wars with awful outcomes rivaling the Hutu slaughter of the Tutsis in Africa in recent years.
Though Europe and North America might not see any of this it is important for all parts of the world to realize that the world is very small right now because of the internet and the fact that ANYONE can fly anywhere on earth within about 20 hours or less. No one should underestimate this one fact and the almost infinite changes it brings to everyone everywhere.
This scenario though onerous at first allows up to about 13 billion people to live underground and mostly work underground and leaves the surface of earth to parks, farming and roads and recreation. This scenario in the long run leads to the most peace, the most stability, the least wars, the least suffering of all the other scenarios IF population is legally stabilized at no more than 13 or 14 billion people ongoing indefinitely. In other words if a maximum population is reached No one can be born until someone passes on. This type of civilization stabilizes earth's humans potentially for thousands of years and prevents all major wars.
