In the past, man’s worst enemy was nature. He lived under the continual threat of famine and pestilence, a wet summer could bring death to the whole nation and every winter was menace. Mountains stood like barrier between people and sea was less a highway than an impassable division. Today nature. thought still an enemy, is an enemy almost completely conquered. Modern agriculture assures us of an ample food supply. Modern transportation has made the resources of the entire planet accessible to all it’s inhabitants, modern medicine and sanitation allow dense population to cover the ground without risk of pestilence. True, we are still at the mercy of the more violent nature convulsions. Against earthquake, hurricane man has as yet, devised no adequate protection. At most times, nature is no longer formidable,she has subdued.
