Light Pollution

The light pollution is something that we overlook as it has robbed generations to see nature at its largest scale. The study shows that as many as 80% population have never seen the Milky Way. When huge power outage occurred in south California in 1990s, these people saw the Milky Way first time in their life. Billions of dollars are wasted every year on the energy by unnecessary lighting in the sky. All the lights outside which are not shielded downwards on the earth surface, pollute the atmosphere. Astronomers have to go to the different islands or mountains to study the stars because of the light pollution. Low-pressure sodium lamps are used in the city of Tucson, AZ which uses a limited amount of wavelength to prevent the light from spreading everywhere. If we do not control the light pollution then the future generations will not be able to enjoy seeing in the dark.
