It all goes back to what I call BOOK II and III; orgnization seeking to have complete control of all humans and their lifespan.
They want us dead by age 40 and anyone born after 1992, if your not dead by age forty, your doctor will be seen as a terrorist, because he failed to do his job. Your local town leaders will be seen as the same, because they didn't add enough poison to the water supply, etc., etc...
This earth is HUGE, it can support trillions more people, but the few families that wish to keep control, see too many people a threat to their survival, their $$$ system.
