Author | Jaime RamosApproximately one half of the population of the European Union and over two thirds of the US population can no longer see the Milky Way. This is not a planetary alignment phenomenon, but a growing problem called light pollution.Mankind’s mark on planet Earth and the industrialisation thereof, is reflected in a series of evils that are threatening to become endemic and which go beyond purely biological aspects. We have changed the future of ecosystems, to such an extent that the Anthropocene is putting, not just other species, but the actual human species, at risk. Of all the forms of pollution, light pollution is one of the most ignored.The fact of losing visual contact with the stars is the clearest consequence, but not the worst. Although humans may consider light pollution to be the most harmless of pollutions, for other animal and plant species it may have tragic consequences.According to the researcher Christopher Kyba, for nocturnal animals, the introduction of artificial light probably represents the most drastic change human beings have made to the environment. Since the crucial role of diurnal and nocturnal cycles assumed by each species are ingrained in the DNA of all the planet’s fauna and flora. Excessive light breaks this pattern.
