Maybe most people know that there is water pollution, air pollution and noise pollution around us, but few people know that there is another kind of pollution—light pollution. In fact, it can be everywhere, depending on the time of the day.
Light pollution is the result of the wasted energy. Instead of providing light for people on the earth, most bright light shines into the sky, because people don’t design lights very well. At the same time, lights are brighter than necessary. All these cause light pollution. Stars in the night sky always provide everyone with wonderful sights(景色), but light pollution prevents them from being seen.
Some scientists say that light pollution can also bring some health problems to people, especially to kids. So it’s the high time for us to do something useful to stop light pollution.
