The ecological impact of artificial light at night has been a rapidly growing field of global change science in recent years. While understanding of direct lighting impacts (for example street lights) has improved dramatically, the effect of artificial skyglow (light that is scattered in the atmosphere and reflected back to the ground) on species behaviours and distributions is lacking. Skyglow extends the geographical influence of artificial lighting from metres to kilometres. It interferes with the detectability of natural light cycles associated with the passage of the moon, which enable many organisms to time important biological events, and orientate themselves in space using the celestial compass. 22% of the world's coastal regions are now exposed to artificial skyglow, the ecological consequences of which are largely unknown.

近年来，夜间人造光的生态影响一直是全球变化科学中快速发展的领域。虽然对直接照明影响（例如路灯）的理解已经大大提高，但缺乏人工天光（在大气中散射并反射回地面的光）对物种行为和分布的影响。Skiglow将人工照明的地理影响从米扩展到公里。它干扰了与月球运行相关的自然光周期的可探测性，这使得许多生物能够对重要的生物事件进行计时，并使用天体罗盘在太空中定位自己。世界上22%的沿海地区现在暴露在人造日光下，其生态后果在很大程度上是未知的。
