Inferno: (Robert Langdon Book 4)

will ‘activate’ only in a certain percentage of people. In other words, the virus is now carried by everyone on earth, and yet it will cause sterility in only a randomly selected part of the population.”
    “What … part ?” Langdon heard himself say, incredulous even to be asking such a question.
    “Well, as you know, Bertrand was fixated on the Black Death—the plague that indiscriminately killed one third of the European population. Nature, he believed, knew how to cull itself. When Bertrand did the math on infertility, he was exhilarated to discover that the plague’s death rate of one in three seemed to be the precise ratio required to start winnowing the human population at a manageable rate.”
    That’s monstrous , Langdon thought.
    “The Black Plague thinned the herd and paved the way for the Renaissance,” she said, “and Bertrand created Inferno as a kind of modern-day catalyst for global renewal—a Transhumanist Black Death—the difference being that those manifesting the disease, rather than perishing, would simply become infertile. Assuming Bertrand’s virus has taken hold, one third of the world’s population is now sterile … and one third of the population will continue to be sterile for all time. The effectwould be similar to that of a recessive gene … which gets passed along to all offspring, and yet exerts its influence in only a small percentage of them.”
    Sienna’s hands were shaking as she continued. “In Bertrand’s letter to me, he sounded quite proud, saying he considered Inferno to be a very elegant and humane resolution of the problem.” Fresh tears formed in her eyes, and she wiped them away. “Compared to the virulence of the Black Death, I admit there is some compassion in this approach. There will be no hospitals overflowing with the sick and dying, no bodies rotting in the streets, and no anguished survivors enduring the death of loved ones. Humans will simply stop having so many babies. Our planet will experience a steady reduction in our birth rate until the population curve actually inverts, and our total numbers begin to decrease.” She paused. “The result will be far more potent than the plague, which only briefly curbed our numbers, creating a temporary dip in the graph of human expansion. With Inferno, Bertrand created a long-term solution, a permanent solution … a Transhumanist solution. He was a germ-line genetic engineer. He solved problems at the root level.”
    “It’s genetic terrorism …” Langdon whispered. “It’s changing who we are, who we’ve always been, at the most fundamental level.”
    “Bertrand didn’t see it that way. He dreamed of fixing the fatal flaw in human evolution … the fact that our species is simply too prolific. We are an organism that, despite our unmatched intellect, cannot seem to control our own numbers. No amount of free contraception, education, or government enticement works. We keep having babies … whether we want to or not. Did you know the CDC just announced that nearly half of all pregnancies in the U.S. are unplanned? And, in underdeveloped nations, that number is over seventy percent!”
    Langdon had seen these statistics before and yet only now was he starting to understand their implications. As a species, humans were like the rabbits that were introduced on certain Pacific islands and allowed to reproduce unchecked to the point that they decimated their ecosystem and finally went extinct.
    Bertrand Zobrist has redesigned our species … in an attempt to save us … transforming us into a less fruitful population.
    Langdon took a deep breath and stared out at the Bosporus, feeling as ungrounded as the boats sailing in the distance. The sirens were growing still louder, coming from the direction of the docks, and Langdon sensed that time was running out.
    “The most frightening thing of all,” Sienna said, “is not that Infernocauses sterility, but rather that it has the ability to do so. An airborne viral vector is a quantum leap—years ahead of its time. Bertrand has suddenly lifted us out of the dark ages of genetic engineering and launched us headlong into the future. He has unlocked the evolutionary process and given humankind the ability to redefine our species in broad, sweeping strokes. Pandora is out of the box, and there’s no putting her back in. Bertrand has created the keys to modify the human race … and if those keys fall into the wrong hands, then God help us. This
