During the turmoil of the 1960's if you wanted to make your point you had to ramp it up and if possible scare people. In 1962 Rachel Carson did this with "Silent Spring" and in 1968 Dr. Paul R. Ehrlich scared the living shit out of millions professing the end of humanity with "The Population Bomb" suggesting population controls ranging from rewarding couples not to have children to forced sterilization.
The truth, the facts, the reality is that developed countries population growth has slowed to a crawl if not gone negative and the developing world's circumstances have changed to an extent parents don't have to have double-digit children to cultivate and harvest crops or ensure the survival of their family name.
Without immigration, many developed countries show negative population growth and my wife is fond of pointing out that the Japanese, basically a closed immigration free society, would rather play video games than F%#k. Japan may be the poster child but they are far from the only country witnessing population collapse. As of March 2017 another 19 countries project negative population growth which has been welcomed by some but for those who understand demographics, including many governments, this is truly scary.
Only in academia could a man with ideas and predictions so absolutely wrong, continue to be embraced by the elite and barely hint at any admission of being wrong or guilty of things done because of his research. Being "wrong" has a price and nothing will bring back millions of people that were never conceived from government rules and pressure to countless of forced sterilizations.
Not only are Paul Ehrlich's ideas still being taught in one of our greatest state sponsored universities, he still serves as the President, Center for Conservation Biology, Professor of Population Studies in a building that no doubt will one day be named after him. Only in America do we continue to reward exceptional incompetence and fail to see the facts for what they are and continue to make political and social decisions based on flawed science.
