"... Reverend THOMAS MALTHUS' prediction made in 1798—that man would reproduce himself into a condition of "misery and vice" because of the growing imbalance caused by the multiplication of his own numbers by geometric progression, while his food supply was increasing arithmetically—is as valid today as when it was made. He was a visionary and saw clearly the monster of overpopulation. The only error in his prediction was one of a "few seconds on the clock of human occupancy of the earth". We, agriculturists, can buy at most a few decades of time in which to bring population growth into successful balance with food production."
