Man will survive as a species for one reason: He can adapt to the destructive effects of our power-intoxicated technology and of our ungoverned population growth, to the dirt, pollution and noise of a New York or Tokyo. And that is the tragedy. It is not man the ecological crisis threatens to destroy but the quality of human life.

Human destiny is bound to remain a gamble, because at some unpredictable time and in some unforeseeable manner nature will strike back.

Human life is now molded to a large extent by the changes that man has brought about in his external environment and by his attempts at controlling body and soul.

...Search for the cause may be a hopeless pursuit because most disease states are the indirect outcome of a constellation of circumstances.

In 1946, Oxford University in England was offered large funds to create a new Institute of Human Nutrition. The University refused the funds on the ground that the knowledge of human nutrition was essentially complete, and that the proposed institution would soon run out of meaningful research projects.

Man shapes himself through decisions that shape his environment.

Nature always strikes back. It takes all the running we can do to remain in the same place.
