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 day or night, summer or winter, 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.)
首先,气候将变得无关紧要,因为它主要是大气层的一种现象。雨、雪、霰、雾将不会给地下世界带来麻烦。甚至气温的变化也局限于露天地表,而在地下则不存在这种变化。不论白天黑夜,炎夏寒冬,地下世界的温度将保持平稳,近乎恒温。如今,当我们的地表环境太冷时,则需要取暖,而太暖时,又需降温,耗费大量的能量。若搬到地下生活,则统统可以省去。天气对人造的建筑物以及人类本身的损害将不复存在。地区性的交通问题也将大为简化。(当然,地震将依然是个危险。)
Second, local time would no longer be important. On the surface, the tyranny of day and night cannot be avoided, and when it is morning in one place, it is noon in another, evening in still another and midnight in yet another. The rhythm of human life therefore varies from place to place. Underground, where there is no externally produced day, but only perpetual darkness, it would be artificial lighting that produces the day and this could be adjusted to suit man's convenience.
其次,地方时间将无关紧要。地球表面昼夜分明,谁也无法避免,一处是早晨,另一处是中午,再一处是黄昏,又一处是午夜。所以人类生活的节奏因地而异。在地下,没有外界生成的白天,而只有永恒的黑暗,人工照明形成白昼,这就可以根据人的需要加以调整。
The whole world could be on eight-hour shifts, starting and ending on the stroke everywhere,at least as far as business and community endeavors were concerned. This could be important in a freely mobile world. Air transportation over long distances would no longer have entail"jet lag." Individuals landing on another coast or another continent would find the society they reached geared to the same time of day as at home.
整个世界都可以实行八小时轮班制,各地都可能做到同时上班,同时下班,至少公务活动和社会活动可以如此。这对于一个自由流动的社会来说极为重要。乘飞机长途旅行将不会再引起"时差反应"。抵达大洋彼岸或另一片大陆的人会发现他们所到的那个社会与自己家乡一样都是按照同一时间运行的。
