Bright city kills

光污染：繁华背后几多忧？
How many stars can you see in the night sky? If the answers are “just a few” or “none”, you might be living with light pollution.
Light pollution happens when too much man-made light harms nature and people. Scientists have found that it is especially harmful to nocturnal (夜间的) animals.
Nocturnal animals sleep in the day and are busy at night. Animal scientist Christopher Kyba said man-made light is “the biggest change” humans have brought to these animals.
Small animals use darkness to hide from predators (捕食者). But, he said, cloudy skies near cities are now “hundreds of times” brighter at night. This means that, for example, cats can catch more rats. Then, there will be too many cats and not enough rats to feed them all.
Baby sea turtles are born on beaches in the nighttime. They find the water by the light of the ocean horizon (地平线). Man-made lights lead them away from the ocean. In Florida alone, “millions … die this way every year,” said the US-based International Dark-Sky Association.
Also, birds that travel or hunt at night need moonlight and starlight. Man-made light can lead them in the wrong direction (方向). Every year, millions of birds die by flying into brightly-lit buildings.

光明之城杀戮
你能在夜空中看到多少星星？如果答案是“很少”或“没有”，你可能生活在光污染中。
当太多的人造光危害自然和人类时，就会发生光污染。科学家们发现它对夜间活动的动物尤其有害。
夜间活动的动物白天睡觉，晚上很忙。动物科学家克里斯托弗·基巴说，人造光是人类给这些动物带来的“最大变化”。
小动物们利用黑暗来躲避捕食者。但是，他说，城市附近多云的天空现在在夜间要亮“数百倍”。这意味着，例如，猫可以抓更多的老鼠。然后，会有太多的猫，而没有足够的老鼠来喂养它们。
小海龟在夜间出生在海滩上。他们在海平线的光线下找到海水。 人造灯光却把他们带离海洋。总部位于美国的国际黑暗天空协会（International Dark Sky Association）说，仅在佛罗里达州，“每年就有数百万（动物）……以这种方式死亡。”。
此外，夜间旅行或狩猎的鸟类需要月光和星光。人造光会把他们引向错误的方向。每年，数以百万计的鸟类因飞向灯火通明的建筑物而死亡。
