As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures require electricity to be lighted. Humans demand these lights. They want their homes more comfortable and streets safe. The problem is that researchers have found that all this light has a negative effect on humans and wildlife as well, so please take care.
Less than 10 years ago I drove to a less populated section of my town , lay down in the middle of the road and watched an attractive meteor shower（流星雨）. The area was short of buildings and street lights. If I did that today, I wouldn’t be able to see the meteor shower, but I would be surely run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as CO2 Pollution. If you have ever taken a flight at night, you must remember the view of colored lights all around--it’s beautiful but wasteful. How extensive this phenomenon is around the world!
Additionally, electricity needs to be created, and the process of creating that electricity will cause pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.
Apart from humans, it has been proved that wildlife is also suffering from light pollution. Thousands of birds die each year when they crash into highly lit buildings, as they are confused which direction they should go in by the light. It has been long known that tiny sea turtles become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. We should not only pay more attention to light pollution, but also reduce light pollution by avoiding using unnecessary lighting.
