In 1973, Paul Ehrlich and his wife Anne H. Ehrlich continued to draw attention to their controversial predictions from The Population Bomb (1968), which forecasted catastrophic overpopulation leading to mass starvation during the 1970s. By 1973, the first half of this decade was already proving these specific predictions wrong, though the Ehrlichs insisted that their underlying concerns about the threats of population growth remained valid. This book presents their arguments.
