Every sign points to a collapsing worldwide population by the end of this century. In his new book Dennis Marx uses statistical and evolutionary analysis to show... That the population explosion of the 20th century has turned into the population implosion of the 21st century. That worldwide human fertility is falling. Humans are currently evolving exponentially faster than at any time in the past. How these new trends will effect business, politics and culture. How business and investment practices can best take advantage of these trends. By examining the demographic details across the globe, Dennis Marx has uncovered a startling fact impacting virtually every country, rich or poor, religious or secular, advanced or agrarian. Human fertility is falling. Every sign points to a collapsing worldwide population by the end of this century. The population explosion of the 20th century has turned into the population implosion of the 21st century and for the centuries following into the new millennium. In his book on predictions for the 21st century, Dennis Marx looks not to sociology, economics or politics for the root causes of the coming population collapse, but to the science of evolution. Man is an animal, he argues, and the houses, cars and businesses of the world are the environment we inhabit. An environment that includes smart phones, computers, the Internet, social media and pornography. This is the environment that men and women survive, mate and procreate in. Using these tools of demographics through the window of evolutionary biology, he develops surprising, and contrarian predictions about the new world we are about to enter. The predictions cover topics from the business of advertising to the future of genocide. The book discusses culture and how the forming of icons and media will be impacted by unprecedented upcoming demographic distributions. The author discusses the economy of this new world and even provides advice on how to alter investing and business practices to exploit the coming changes. Dennis Marx uses the US Census Bureau's own international population statistics as well as numerous other sources to prove these points. He also provides an extensive bibliography at the end of his book that provides the reader with additional material for further study of this very interesting and timely topic.
