The authors of the new paper use a host of historical data going back 6,000 years ago to uncover just what conditions make humans tick. It turns out people can make do with all levels of rainfall, with humans living in all but the very driest places on Earth. Civilization has also adapted to all types of soil fertility. The biggest limiting factor in terms of human habitation is how hot it gets.
这篇新论文的作者使用了近6000年的大量历史数据来揭示人类生存的条件。事实证明,除了在地球上最干旱的地方,人类都可以设法应对各种程度的降雨。文明也适应了各种类型的土壤肥力。人类居住的最大限制因素是温度会有多高。
The results of the study show people thrive in a narrow temperature band, where the average annual temperature spans 11 to 15 degrees Celsius or roughly the 50s if you’re into Fahrenheit. It’s in that belt where many staple crops grow best and livestock can be highly productive, and it’s why the authors define it as the “human climate niche.” That’s not say there aren’t other confounding factors for human thriving, but temperature is one of the key elements linked with well-being.
研究结果显示,人们只能在一个狭窄的温度范围内生活得很好,这一范围是年平均温度在11到15摄氏度之间,如果你喜欢华氏温度,那大概就在50多华氏度左右。正是在这一范围内,许多主食作物长势最好,牲畜产量也很高,这也就是作者将其定义为“人类气候生态位”的原因。这并不是说没有其他影响人类健康的因素,但温度是影响健康的关键因素之一。
