We live in a polluted world, although we have advanced technologies. Nature is covered in scrap, many animal species disappear. There is a type of pollution that many are not aware of – light pollution, considered to be cancer of astronomy.
According to the latest research, 30% of the public lighting is wasted because of the age-old design of public illumination, mounted on poles incorrectly. In Bucharest, 6.25 billion lei per year is wasted on lighting the sky. The solution is simple. It requires the use of lights which direct the light down. Learn what light pollution is and lower your consumption. (CAMELIA GLIGOR)
