USA和欧洲的光污染：好的，坏的和丑陋的
Light pollution in USA and Europe: The good, the bad and the ugly
摘要：
光污染是一个世界性的问题，对人类健康和自然生态系统产生一系列不利影响。使用新世界人造夜空亮度地图集的数据，VIIRS记录的辐射和国内生产总值（GDP）数据，我们比较了光污染水平，以及美国州和县一级和欧洲地区（NUTS 2）和省（NUTS 3）一级的人口规模和GDP的光通量。我们发现，欧洲污染最严重和污染最轻的地区之间存在6800倍的差异，人均光通量差异为120倍，单位GDP通量差异为267倍。然而，我们发现美国各县之间的差异更大：天空污染差异为20万倍，人均光通量差异为1.6万倍，单位GDP光通量差异为4万倍。这些发现可以为决策者提供信息，帮助减少能源浪费以及与光污染相关的不利环境，文化和健康后果。
英文摘要：
Light pollution is a worldwide problem that has a range of adverse effects on human health and natural ecosystems. Using data from the New World Atlas of Artificial Night Sky Brightness, VIIRS-recorded radiance and Gross Domestic Product (GDP) data, we compared light pollution levels, and the light flux to the population size and GDP at the State and County levels in the USA and at Regional (NUTS2) and Province (NUTS3) levels in Europe. We found 6800-fold differences between the most and least polluted regions in Europe, 120-fold differences in their light flux per capita, and 267-fold differences in flux per GDP unit. Yet, we found even greater differences between US counties: 200,000-fold differences in sky pollution, 16,000-fold differences in light flux per capita, and 40,000-fold differences in light flux per GDP unit. These findings may inform policy-makers, helping to reduce energy waste and adverse environmental, cultural and health consequences associated with light pollution.
