There's more to it than what you have listed, there is exponential growth in the population, money supply, debt, and then there is the theory of peak oil. I would highly recommend going to Chris Martenson's website and take the free "Crash Course". If you don't want to watch the whole thing at least watch, 3, 4, and 17a, b, c.
I have no connection to Chris but it really opened my eyes to what is really going on. Another thing to watch would be Alex Jones "Endgame", I know he's a conspiracy theorist but there are some things in it that fill in pieces of the puzzle. The Georgia Guidestones really makes me wonder whats going on.
Freedomforce International is another place to find information, this is G. Edward Griffins website who wrote The Creature from Jekyll Island.
I believe there is a group of people who want to cut the population of the world down to around 500 million people, (Tom Clancy wrote a novel about that called "Executive Orders") using starvation, biological weapons, and war. I'm wondering how they will decide who lives and who dies because it would be advantageous to keep intelligent and skilled people alive. Hope I'm wrong, but this is where I'm at right now.
