Like winds and sunsets, wild things were taken for granted until progress began to do away with them.

Aldo LeopoldAgricultural science is largely a race between the emergence of new pests and the emergence of new techniques for their control.
Aldo LeopoldOne of the anomalies of modern ecology is the creation of two groups, each of which seems barely aware of the existence of the other. The one studies the human community, almost as if it were a separate entity, and calls its findings sociology, economics and history. The other studies the plant and animal community and comfortably relegates the hodge-podge of politics to the liberal arts. The inevitable fusion of these two lines of thought will, perhaps, constitute the outstanding advance of this century.
