A gradual (completed long after 2024) growth of two types of territory out of the industrial world will emerge that is overcrowded and inhospitable to human life and nature. "I will conditionally term them "Work Territory" (WT) and "Preserve Territory" ( P T ). The PT, larger in area, will be set aside for maintaining the earth's ecological balance, for leisure activities, and for man to actively re-establish his own natural balance."
Sakharov, A. (1974) Tomorrow: The View From Red Square, Saturday Review, 14-20, August, p. 12-14, 108
