Unit10 climate and people’s life
Man has been on earth about one million years. He has managed to live on very part of the planet, even thought some climates have made life more difficult than others. Sometimes man moved; sometimes he remained and endured the discomforts. Where man has remained, he apparently has undergone some physical changes that have helped him adapt to his climate.
It is thought that differences in skin color are the result of climatic adaptation. People from hot climates generally have burning black or brown skin that resists the sun’s burning rays. The lightest skinned people generally come from colder regions, where they have less exposure to the sun. people with skin of other color, such as yellow, red, and olive, generally come from areas where they have also had to adapt to other climates.
Man’s size also seems to vary according to climate. People living in colder regions are generally larger than those living in hotter ones. This difference might be explained by the fact that big people have less skin compared to his weight, the easier it is for him to keep warm.
As part of the natural environment, climate greatly affects human activities. Climate has significant effect on agriculture. Climatic factors such as the length of the growing season, the total amount of rainfall, and the daily and seasonal changes in temperature restrict the kinds of crops that can be grown.
Climate also affects transportation. In areas of frequent storms, transportation is often slowed down or interrupted. Water transportation in many areas is impossible if the river is frozen. Land transportation may be blocked by heavy snowfall. Air travel especially is affected by stormy weather.
Major concentrations of population in the world are in the humid, warmer regions, where the development of agriculture is not restricted by poor climatic conditions. Fewer people live in areas with very dry, very wet, or very cold climates. However, with the development of technology, such as air conditioning and central heating, people are becoming less confined to so-called favorable climates.
It is true that man changes his living habits in order to adjust to climate, but climate changes his
as well, though more slowly. Man adapts constantly to changes, and science has played an important part in helping people adjust to almost any condition. By learning more about his climate , man will find a way to adapt to or control it and live a more comfortable life.

气候和人的生活

人类在地球上已大约有一万年了。几乎这星球的每一部分都有人居住，虽然有些地方的气候条件比较恶劣。有时人会迁徙，有时人会留下来，即使要忍受不适。那里留下来的人，生理上显然会发生转变，来适应当地的气候条件。

肤色的深浅有别就被视为适应当地气候的结果。炎热气候的人一般都有著炭黑或深褐色的皮肤，以抵抗灼热的阳光。皮肤最浅色的人通常来自寒冷地区，在那里的人们少会暴露在阳光之下。其它肤色，如黄、红及橄榄色的肤色，一般都是因为要适应该地区的气候。

人的体型大小似乎也是随著气候变化的。相比生活在炎热地区的人，寒冷地区的人通常体型较大。造成这差异，可能是由于体型大的人，皮肤的面积与体重相比较少，更易保暖防寒。

作为天然环境的一部分，气候对人类的活动造成极大的影响。气候对农业起了显著作用。气候因素，如生长季节的长短、总降雨量、每日及季节的温度变化，皆限制了可生长的农作物的种类。

气候也会影响交通。在风暴频繁的地区，交通经常会受延误或中断。如果地域的河水结冰，那就不可能作水路运输。大雪封锁亦可能瘫痪陆上运输。暴风雨对航空交通特别有影响。

世界人口主要集中在潮湿的温带地区，那里的农业发展不受恶劣气候条件所限制。人都不喜欢居住在气候非常干燥、非常潮湿或非常寒冷的地区。然而，随着科技进步，如空调和中央暖气，人们越来越不局限于所谓的有利气候条件。

人的生活习惯会随著适应气候而改变，但气候本身也在转变，虽然速度比较慢。人不断地适应变化，科学发明帮助人类适应几乎任何条件，可谓居功至伟。通过认识气候，人会找到适应或控制气候的方法，来让更生活过得更舒适。
