Robert Sheckley quotes
Nature also gives rain and drought, heat and cold; and thoughtfully ensures that the rain rots man's food, the drought parches it, the heat scalds man's body, and the cold freezes his limbs.
These are only nature's milder aspects, not to be compared to the wrathfulness of the sea, the frigid indifference of the mountains, the treachery of the swamp, the depravity of the desert, or the terror of the jungle. But I noticed that nature, in her hatred of mankind, provided that most of the earth's surface be covered with sea, mountains, swamp, desert, and jungle.
