I hope never. Google "population forecast earth." We're already overpopulated for the carrying capacity of the land at a rate of at least 100:1.
This is all we need to drive the species to extinction faster. Of course, only rich white guys (think Donald Trump) would be able to afford it. So instead of a population of 15 billion and starvation on a mass scale, wars over water and arable land, runaway virus pandemics, think about a bunch of Donald Trumps, old enough their scrota sag to their kneecaps, alive for 500 years.
Sound so appealing now?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
