In 1970, Stanford professor Paul Ehrlich published a famous book, The Population Bomb, in which he described a disastrous future for humanity: “The battle to feed all of humanity is over. In the 1970s and 1980s hundreds of millions of people will starve to death.”
Looking at population demographics, it's plain to see we're in trouble now. A society with no babies, has no future. We're all gonna starve to death with food riots tearing apart the fabric of society while the cities all burn.
Better make sure you got your long term food and water storage, seed banks and grid-out cooking skills up to snuff!
