Measuring Light Pollution

A worlwide problem

Among modern environmental problems, light pollution, understood as the alteration of the natural brightness of the sky due to artificial light sources, is the one that has most increased in recent times. Although its effects are most notorious in highly populated areas and developed countries, it is beyond doubt a very serious worldwide problem: nowadays, at least 60% of the Earth’s population lives under light polluted skies and in Europe and the USA the fraction increases up to more than 80%. Despite the increasing social awareness, the efforts of the scientific community and the citizens’ actions to mitigate the problem, light pollution is still increasing at a yearly basis rate of 2%.
