For example, we go to a tropical island and with the aid of DDT we stamp out malaria and, in two or three years, save hundreds of thousands of lives. This is obviously good. But the hundreds of thousands of human beings thus saved, and the millions whom they beget and bring to birth, cannot be adequately clothed, housed, educated or even fed out of the island's available resources. Quick death by malaria has been abolished; but life made miserable by undernourishment and over-crowding is now the rule, and slow death by outright starvation threatens ever greater numbers.
And what about the congenitally insufficient organisms, whom our medicine and our social services now preserve so that they may propagate their kind? To help the unfortunate is obviously good. But the wholesale transmission to our descendants of the results of unfavorable mutations, and the progressive contamination of the genetic pool from which the members of our species will have to draw, are no less obviously bad. We are on the horns of an ethical dilemma, and to find the middle way will require all our intelligence and all our good will.
III Over-Organization
The shortest and broadest road to the nightmare of Brave New World leads, as I have pointed out, through over-population and the accelerating increase of human numbers — twenty-eight hundred millions today, fifty-five hundred millions by the turn of the century, with most of humanity facing the choice between anarchy and totalitarian control. But the increasing pressure of numbers upon available resources is not the only force propelling us in the direction of totalitarianism. This blind biological enemy of freedom is allied with immensely powerful forces generated by the very advances in technology of which we are most proud.
