Man, not the earth, makes civilization

The influence of geographic factors diminishes as technology grows. The character and contour of a terrain may offer opportunities for agriculture, mining, or trade, but only the imagination and initiative of leaders, and the hardy industry of followers, can transform the possibilities into fact; and only a similar combination (as in Israel today) can make a culture take form over a thousand natural obstacles. Man, not the earth, makes civilization.
