If [the loss of fertility of the soil and the loss of soil as a renewable resource] does happen, we are familiar enough with the nature of American salesmanship to know that it will be done in the name of the starving millions, in the name of liberty, justice, democracy, and brotherhood, and to free the world from communism. We must, I think, be prepared to see, and to stand by, the truth: that the land should not be destroyed for any reason, not even for any apparently good reason. We must be prepared to say that enough food, year after year, is possible only for a limited number of peaople, and that this possibility can be preserved only by the steadfast, knowledgeable care of those people.
