First,weather would no longer be important,since,it is primarily a phenomenon of the atmosphere.Rain,snow,sleet,fog would not trouble the underground world.Even temperature variations are limited to the open surface and would not exist underground.Whether dayornight,summerorwinter,temperatures in the underground world remain equable and nearly constant.The vast amounts of energy now expended in warming our surface surroundings when they are too cold,and cooling them when they are too warm,could be saved.The damage done to manmade structures and to human beings by weather would be gone.Transportation over local distances would be simplified.（Earthquakes would remain a danger,of course.）
