I was starting to reread "How did we get Here?" today

 This (to the best of my ability as a (precognitive psychic) is what we are presently dealing with here on earth. People went forward in Time in the Air Force trained to fly the flying saucers bought by Eisenhower when he was president to prevent nuclear annihilation. Well, even though around 50 blowups (nuclear blow ups of everything from whole cities to whole countries to the earth itself being destroyed we were able to retroactively erase all these things from our present timeline at least.

However, in some ways overpopulation is a much more difficult problem to solve than single events like a nuclear accident of terrorists blowing up a city or area or even the whole world. All you have to do then is to kill them before they can do this by altering time before they did this. This is pretty easy once you have access to time travel like Eisenhower bought us in the early 1950s.

However, trying to prevent human extinction from overpopulation was much harder to get enough countries to agree on this. However, at least Europe and Canada and England and Australia and New Zealand and China and Russia agreed we had to do this to prevent human extinction. Most of the rest of the world agreed too.

So, my thought is that coronavirus variants and global Climate change are thought to be the way we go from 8 billion down to 1 billion or less by 2100 Ad at present.

I'm thinking when they designed this virus (on earth or off of earth) that it was designed to infinitely create variants along the way.

The danger here of course is that it could kill everyone within 20 or 30 years, especially if they choose not to get the antidotes of vaccines and boosters worldwide.

So, I'm thinking that eventually whole families will likely now be wiped out completely (over time like 50 years) to where their genetics will be gone from earth completely by 2100 that choose not to get a vaccine.

This is what I think is going on right now to the best of my ability. Of course this is only one view of a million or more depending upon who you are and whether you are from earth or not.
