"Despite the prominence that "magic bullets" and "wonder drugs" hold in the layman's mind, most of the really decisive battles in the war against infectious disease consisted of measures to eliminate disease organisms from the environment. An example from history concerns the great outbreak of cholera in London more than one hundred years ago. A London physician, John Snow, mapped occurrence of cases and found they originated in one area, all of whose inhabitants drew their water from one pump located on Broad Street. In a swift and decisive practice of preventative medicine, Dr. Snow removed the handle from the pump. The epidemic was thereby brought under control - not by a magic pill that killed the (then unknown) organism of cholera, but by eliminating the organism from the environment."

¿Quién ha tomado la decisión que pone en movimiento esa cadena de envenenamientos, esa ola creciente de muerte que se va extendiendo como las ondas que se forman cuando se lanza una piedra sobre un estanque tranquilo? ¿Quién ha puesto en un platillo de la balanza las hojas que podrían haberse comido los escarabajos y en el otro los lastimosos montones de plumas de diversos colores que forman los restos sin vida de las aves que cayeron bajo el golpe generalizado de los venenos insecticidas? ¿Quién ha decidido (quién tiene derecho a decidir) en nombre de legiones sin cuento de personas que no fueron consultadas, que el valor supremo corresponde a un mundo sin insectos, aunque tenga que ser también un mundo estéril, privado de la gracia de una bandada de aves en vuelo? Esa decisión es la del autoritario revestido temporalmente de poder; ha sido tomada durante un momento de distracción de millones de personas para las que la belleza y el mundo ordenado de la naturaleza tienen todavía un significado que es profundo y perentorio.
The chemicals to which life is asked to make its adjustment are no longer merely the calcium and silica and copper and all the rest of the minerals washed out of the rocks and carried in rivers to the sea; they are the synthetic creations of man’s inventive mind, brewed in his laboratories, and having no counterparts in nature.
When one is concerned with the mysterious and wonderful functioning of the human body, cause and effect are seldom simple and easily demonstrated relationships. They may be widely separated both in space and time. To discover the agent of disease and death depends on a patient piecing together of many seemingly distinct and unrelated facts developed through a vast amount of research in widely separated fields.
