8.As the population of the planet increases,so does the number of homes,business,parking lots,schools,airports and roadways.All these structures use electricity and need to be lighted.Humans demand light.They want their homes more comfortable and they want their streets safe.The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10years ago I drove to a thinly populated section of my own,lay down in the middle of the road and watched an attractive meteor shower(流星雨).If I did that today,I wouldn't be able to see the meteor shower.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide (二氧化碳)pollution.One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted.One only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky:a total waste of electricity.
Additionally,the production of electricity creates pollution by releasing greenhouse gases.This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife.Thousands of birds die each year when they crash into highly lighted buildings,as they become puzzled by the light.It has been long known that tiny baby sea turtles become lost and follow the light 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.Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.
