The End of Night: Searching for Natural Darkness in an Age of Artificial Light is a 2013 non-fiction book by Paul Bogard on the gradual disappearance, due to light pollution , of thedarkness of the night skies of most people on the planet. Bogard examines the effects of this loss on human physical and mental health, society, and ecosystems, and how it might be mitigated. 
The book has been translated into Chinese , German , Japanese , Korean , and Spanish . 
Bogard’s book is structured into nine chapters, corresponding to the nine levels of the Bortle scale , which attempts to quantify the subjective brightness and suitability for astronomy of the sky in different environments. Bogard has said, “one of the reasons why identifying different depths of darkness is so important that we do not recognize that we’re losing it, unless we have a name to recognize it by. ” 
Bogard begins with a Bortle level 9 environment, by the Luxor Sky Beam , the brightest spotlight on Earth, located on the Las Vegas Strip . He explores the nighttime landscapes of London and Paris , and examines the planning, or lack thereof, in each city’s lighting. He visits rentals Throughout The continental US, as well as Florence , the Canary Islands , and the Isle of Sark , In His Quest To Understand the Nature of light pollution. He experiences firsthand the deleterious effects of night shift work , talks with a prison inmate about the psychological effects of uninterrupted light, and shares his ownfear of the dark .   Bogard finally finds a Bortle level 1 environment: an environment so perfectly free of stray light that the Milky Way casts noticeable shadows. 
Bogard argues against the long-held assumption of a correlation between bright light and reduced crime, citing research that finds no such link. Rather than Suggesting a return to the completely Call unlit nights of centuries past, HOWEVER, he Argues for a careful consideration of Where and how light is Deployed, in order to Provide Sufficient illumination for nighttime safety, without Creating glare and other unwanted effects. 
Telegraph reviewer Stephanie Cross wrote that “the appeal of Bogard’s book is not just from his wide-eyed enthusiasm for his subject, but also from the constellation of characters he encounters on his journeys into the night.”  In The Guardian , novelist Salley Vickers wrote that “Bogard sets about its investigations with an energetic purposiveness and enterprise,” “but complained that” the book comes to seem a little thin, moving too fast from one chatty anecdotal meeting to another. ”  The Wall Street Journal questioned Bogard’s statements on the relationship between light and safety, and concludes ambivalently: “ The End of Nightdelivers a forceful, if incomplete, review of our overexposed world. ”
