The world is facing a public-health emergency. According to the World Health Organization, the Zika virus, a horrific disease that causes malformation of infants, is now “spreading explosively.” If decisive action is not taken quickly, Zika will proliferate to every continent, become widely and deeply embedded in populations, and cause millions of babies to be born brain-damaged every year for generations to come.
A cure for Zika is not known, and it could take decades to find one. But there is something that can be done now to stop the epidemic. Zika is spread by mosquitoes, which can be exterminated by pesticides. The most effective pesticide is DDT. If the Zika catastrophe is to be prevented in time, we need to use it.
Some history is in order. DDT was first employed by the U.S. Army to stop a typhus epidemic in Naples that had been created by the retreating Germans through their destruction of that city’s sanitation system. Subsequently, Allied forces used it in all theaters to save millions of disease-ravaged victims of Axis tyranny, and after the war employed it to wipe out malaria in the American south, southern Europe, and much of south Asia and Latin America. The benefits of these campaigns were unprecedented. As the National Academy of Sciences put it in a 1970 report:
To only a few chemicals does man owe as great a debt as to DDT. It has contributed to the great increase of agricultural productivity, while sparing countless humanity from a host of diseases, most notably perhaps, scrub typhus and malaria. Indeed, it is estimated that in little more than two decades, DDT has prevented 500 million deaths due to malaria that would otherwise have been inevitable.
The role of DDT in saving half a billion lives did not positively impress everyone, however. On the contrary, many environmentalist leaders were quite upset. As Alexander King, the co-founder of the Club of Rome, put it in 1990, “my chief quarrel with DDT in hindsight is that it has greatly added to the population problem.” Of course, such reasoning would carry little appeal to the American public.
