Light pollution

It is not actually about ecology but still there is such kind of pollution as light pollution. People are afraid of darkness and they need light all around then and they do their best in order to get rid of darkness and to have more light around them. They have lamps and lights and so on and so forth. And they have actually managed to make their cities as bright at night as those are at day. Though, chasing for the light at night on the earth people have list the light in the sky, they see no stars at night and it is a result of light pollution. The lights of the cities are so bright and there are so many of those that night sky is lightened and there are no stars people can see. They deprive themselves of the opportunity to see the night beauty of the sky because they are too afraid of darkness. Well, such a pollution never influences people of nature around them if not considering the fact about capacity that is needed to make all those lights bright and this capacity comes from the earth because there is no another place people can get it from.
