A very dark view/thought/idea.
To reduce the human population, all you need is a good old fashioned conventional/biological war. You can get double or even triple-digit percentages during that “culling”.
To try and slowly reduce the population with like global climate change/populace control, is not going to work so well for the people wanting that. That is just going to get billions of furiously frustrated people in the end and that is not going to work out so well for anyone in the “one-world government” in the end. No quick double or triple digits like with a good old fashioned war.
So now I wonder, by not wanting to engage in a world war, instead using global climate change/populace/media control/police states, is that because the “one-world government” may be scared that they may also get caught in the process when some nation/s react badly and go nuclear on their arses?
Now I wonder, does having nuclear capabilities mean one is keeping the “one-world government” at bay?
Ok, back to the real issue. I think it all is about money and power, the richer “they” get the more “they” want to keep it the less they care for the masses. The “one-world government” will come as a desperate last ditch attempt at keeping that control over the masses, which will work for a while until the masses one-day stops and says: ENOUGH!!!
With a “Be gone you are.” in Youda’s voice.
That will reset it all.
