"Among the sciences, there is one little fellow named Ecology, and in time we shall pay him more attention. He teaches us that the total economy of this planet cannot be guided by and efficient rationale of exploitation alone, but that the exploiting part must itself eventually suffer if it too greatly disturbs the balance of the whole (as big beasts would starve, if they succeeded in catching all the little beast that are their prey—their very lack of efficiency in the exploitation of their ability as hunters thus acting as efficiency on a higher level, where considerations of balance count for more than considerations of one-tracked purposiveness).
So far, the laws of ecology have begun avenging themselves against restricted human concepts of profit by countering deforestation and deep plowing with floods, droughts, dust storms, and aggravated soil erosion. And in a capitalist economy, these trends will be arrested only insofar as collectivistic ingredients of control are introduced, as with the comparatively insignificant efforts that have already been organized by our state and federal governments."
