THE CITY DARK chronicles the disappearance of darkness. The film follows filmmaker (and amateur astronomer) Ian Cheney (KING CORN, BIG RIVER,TRUCK FARM), who moves to New York City from Maine and discovers an urban sky almost completely devoid of stars. He poses a deceptively simple question, 'What do we lose, when we lose the night?'.
Exploring the threat of killer asteroids in Hawai'i, tracking disoriented hatching turtles along the Florida coast, and rescuing birds on Chicago streets injured by collisions with buildings, Cheney unravels the myriad implications of a globe glittering with lights--including increased breast cancer rates from exposure to light at night, and a generation of kids without a glimpse of the universe above. In six chapters weaving together cutting-edge science with personal, meditative sequences reflecting on the human relationship to the sky, THE CITY DARK shines new light on the meaning of the dark. 
The film features stunning astrophotography and a cast of eclectic scientists, philosophers, historians, and lighting designers including Hayden Planetarium director Neil deGrasse Tyson, astronaut Don Pettit, neurologist Dr. George Brainard, Harvard Medical School scientist Dr. Steven Lockley, cosmologist Chris Impey, and lighting designer Herve Descottes.
'The City Dark is a thought provoking, revealing and judicious film. Aware people will greatly appreciate the long-awaited appearance of a documentary that finally brings to light some dangerous distortions of our society. For the unaware, the unfortunately large proportion of inhabitants of our planet, the film will be an eye-opener. Cheney beautifully links astronomy to biology, with social and anthropological ramifications that should be conveyed to our politicians. As clock biologist and amateur astronomer, I loved this film!' Dr. Paolo Sassone-Corsi, Distinguished Professor and Director, Center for Epigenetics and Metabolism, University of California-Irvine
'A clear, concise, well-documented exploration of a seldom-considered issue while simultaneously proposing answers to help offset it. Those concerned about the environment, wildlife, human health, and our vanishing cultural heritage will find The City Dark an enlightening view.' Brent Marchant, Library Journal
'Entertaining and thought-provoking...Mr. Cheney's film is a personal lament for the star-filled night sky he experienced growing up in Maine, but it is neither sorrowful nor a rant; he somehow manages to give this engaging work a sense of humor. He also manages to make it smart...This film makes you want to go find a starry sky to camp under quickly, before it's all gone.' Neil Genzlinger, The New York Times
'This film puts an engaging personal touch on the question of why have the stars disappeared from urban skies around the world. And more importantly, what have we lost because of this light pollution? The story is not just for astronomers - you'll never look at the sky in quite the same way again.' Dr. Woody Sullivan, Professor, Astronomy Department, University of Washington, Co-editor, Preserving the Astronomical Environment
'The City Dark takes viewers to the dark side. Most people on this planet are city dwellers that have never seen a truly dark sky...Cheney shows viewers just how dramatically our view of the night sky is being altered by urbanization. Like the rain forests and wildlife habitats, urbanization is eating away the primeval dark sky, to the point where most people rarely see anything up there but the Moon and a few bright planets...The City Dark won't leave you in the dark about light pollution. It's a must see for city dwellers who don't know what they're missing!' Dr. Terry D. Oswalt, Professor and Head, Physics and Space Sciences Department, Florida Institute of Technology
'A compelling journey of learning and realization that delves into the basic questions raised by the explosive spread of electrical lighting in the past 125 years: What does it mean to our place in the universe to not see the stars? What does it mean for our own health and that of other species to be exposed to light at night? Why do we light the night? What can we do about it? The images and stories speak for themselves, nudging the viewer through a gradual transition from appreciating the beauty of sparkling city lights, to recognizing their damaging effects on people and other species, to imagining a healthier and more sustainable future. The City Dark is an excellent introduction to an under-appreciated topic, which it approaches in a fair-minded and balanced manner.' Travis Longcore, Associate Professor, Spatial Sciences Institute, University of Southern California, Co-Editor, Ecological Consequences of Artificial Night Lighting
'The City Dark is the most comprehensive and intelligent documentary on light pollution to have been produced. Ian has examined the societal issues related to the rise of light pollution in a way that tries to challenge the viewer to think differently about the way we use outdoor lighting. He has also been able to distill the sometimes complex technical issues related to light at night (LAN) into a very accessible and informative source of information that anyone can use.' Bob Parks, Executive Director, International Dark-Sky Association
'Comprehensive...helps us discover that night skies are more than just a pretty tableau--although the striking nighttime cinematography in the film never lets us forget how lovely they are...A great way to demonstrate that astronomy has real world implications and its importance to our everyday life.' Green Teacher
'Highly recommended for general audiences...The video provides excellent support for astronomy, urban studies and environmental curricula. Perhaps the first non-planetarium experience of the stars for inner city viewers, the film will remind all of the humbling vastness and extraordinary beauty of the universe.' Cliff Glaviano, Bowling Green State University, Educational Media Reviews Online
'Poetic and visually arresting (even hypnotic)...Stunning astrophotography...Highly recommended.' Video Librarian
'The City Dark is an extraordinarily thoughtful documentary, highly recommended especially for public and school library collections.' The Midwest Book Review
'Thought-provoking...Reminds viewers to appreciate a star-filled night sky and our place in the universe.' Booklist
'The most important thing The City Dark has to tell us is that by losing touch with the stars, we've lost touch with something that inspired our distant ancestors in a profoundly spiritual way...It's no accident, observes [Hayden Planetarium's Neil deGrasse] Tyson at one point, that so many ancient people focused their religious yearnings on the stars--mysterious, glorious beacons that blazed down from skies unpolluted by city lights.Those stars may not become any more visible soon, but the movie will.' Michael Lemonick, TIME 
'Wonderful film...The myriad implications of a planet glittering with artificial lights are explored, from increased health risks to a generation of kids deprived of the wonders of the universe. Featuring stunning astrophotography and a cast of eclectic scientists, historians, and lighting designers, The City Dark is a cautionary tale of light pollution and the disappearance of the night sky.' San Francisco Green Film Festival
'An informative, well-rounded look at light pollution told with a star-gazing enthusiast's passion for his subject...Impressive images of star-filled nights will remind audiences of childhood trips to the planetarium, and few will fail to notice the difference when they next look up into the heavens.' Variety
'Ian Cheney did a wonderful job with this movie...A very personal, compelling, and unique perspective on the issues of light pollution and the disappearing stars...Unexpectedly, this film also teaches us about humility, i.e. not focusing entirely on or thinking too highly of ourselves, but putting ourselves and our lives in proper perspective. Specifically, by looking at the stars and thinking about the greater universe, we should come to realize how little we know and how small we are in the grand scheme of things.' Clement Lau, UrbDeZine
'A crucial film...We've documented light pollution in our own neighborhood and urge others to do the same...This is one you definitely shouldn't miss.' David Dickinson, Astro Guyz
''What do we lose when we lose the night?' Cheney wonders. It's a haunting question. He doesn't try to answer it head on (how could he?). Instead, he peers at it from unexpected angles.' Boston.com
'A City Dark really makes you think about what kind of alternatives are both sustainable and feasible.' Louis Proyect: The Unrepentant Marxist
'I didn't know how long the documentary would hold the attention of a fidgety fourth-grader. But he was immediately drawn into Cheney's quest. He was shocked that astronomy students on Staten Island were able to see only the very brightest stars and planets in New York City's light-polluted skies. He asked me to stop the film after a segment that showed baby sea turtles traveling toward lighted parking lots and strip malls--and death--and away from the ocean...When the film was done, he hugged me for a long moment. 'I'm glad we have a night sky,' he said.' Kristen Laine, Appalachian Mountain Club's Great Kids, Great Outdoors
'Ian Cheney's film was an eye-opening exploration of light pollution and our culture of lighting up the night sky...I want to help bring attention to light pollution because of the negative effects it has on humans and animals alike.' Green Schools Alliance blog 
'Quiet, reflective...It changed the way I look at the city, the sky, the stars, and night itself.' Matt Zoller Seitz, Vulture
'Light pollution? If that topic seems a tad under the radar, the excellent documentary The City Dark may put an end to that...Poetic, at times profound.' Gary Goldstein, Los Angeles Times
'The City Dark invites you to look outside of yourself...An absolutely beautiful film from its quiet, nostalgic beginning to the final rapid-fire revelations from the compelling individuals we meet throughout.' Nick GioBarbieri, The Austinist
'Endlessly fascinating film wizardry...Cheney seems to present viewers with a magical new pair of metaphorical glasses.' Prairie Miller, News Blaze
'This year one of the true standout films...Very entertaining and thought-provoking film...Quite humorous, visually engaging, and will hold your attention throughout.' Garry Denny, Director of Programming, Wisconsin Public Television
'Visually arresting and even hypnotic...I was transfixed...It's an eye-opener.' Charles Cassady, Jr., Cleveland Movie Blog 
'[The film] is like a plaintive love song to the night skies...Elegant and poetic...Ian Cheney has built a bridge with this documentary, hoping to give us a new appreciation for the jewels of the darkened sky.' Jana J. Monji, Chicago Sun-Times 
'Illuminating...Definitely worth watching, even if you have a lovely view of the night sky right outside your window.' Whitney Matheson, USA Today
'One must admire the writer-director-producer's talent and tenacity...The City Dark brings awareness to something most of us take for granted.' Eric Monder, Film Journal International
'Eloquent and compelling...The City Dark puts us back in touch with the deep yearning and mystical appreciation we have for night skies filled with bright and awesome stars!' Frederic and Mary Ann Brussat, Spirituality and Practice
'Illuminating...Cheney's film is well worth the time, though its conclusions will likely keep you up at night.' Joe Neumaier, New York Daily News

 00:00:02.500 --> 00:00:04.033
 [car horn blares]
 
 00:00:04.067 --> 00:00:05.200
 [whistles blasting]
 
 00:00:05.233 --> 00:00:06.400
 [car horn honks]
 
 00:00:07.867 --> 00:00:08.867
 - What is it?
 
 00:00:08.900 --> 00:00:14.133
 This is November 25th.
 
 00:00:16.900 --> 00:00:19.167
 I can\'t even see one star.
 
 00:00:19.200 --> 00:00:24.933
 November 25th at 6:00
 in the freezing cold.
 
 00:00:24.967 --> 00:00:26.433
 Is that a star?
 
 00:00:26.467 --> 00:00:28.033
 Oh, yeah.
 
 00:00:28.067 --> 00:00:30.033
 Oh, there\'s another.
 
 00:00:30.067 --> 00:00:32.133
 Two.
 
 00:00:32.167 --> 00:00:35.000
 Oh, now I\'m getting
 now I\'m getting it.
 
 00:00:36.700 --> 00:00:40.633
 Six, sev or, no,
 I already got that one, I think.
 
 00:00:40.667 --> 00:00:42.300
 Now, I can only see
 about half of the sky
 
 00:00:42.333 --> 00:00:43.467
 \'cause of this building,
 
 00:00:43.500 --> 00:00:45.167
 so we\'ll assume
 there\'s 12 stars.
 
 00:00:45.200 --> 00:00:47.500
 [mellow acoustic music]
 
 00:00:47.533 --> 00:00:51.333
 So I live in a city a big city
 
 00:00:51.367 --> 00:00:52.500
 with 8 million people
 
 00:00:52.533 --> 00:00:56.367
 and, on most nights,
 only a few dozen stars.
 
 00:00:58.733 --> 00:01:03.433
 I\'d grown up spending much
 of my childhood in rural Maine,
 
 00:01:03.467 --> 00:01:06.100
 small town, 4,000 people.
 
 00:01:06.133 --> 00:01:08.767
 At night, more stars
 than I could count
 
 00:01:08.800 --> 00:01:10.300
 or even capture with my camera.
 
 00:01:11.633 --> 00:01:14.267
 - [singing]
 Do-do, do-do
 
 00:01:14.300 --> 00:01:16.267
 Do-do, do-do
 
 00:01:16.300 --> 00:01:18.933
 Do, do...
 
 00:01:18.967 --> 00:01:22.533
 - I built my own telescope
 out of an old cardboard tube,
 
 00:01:22.567 --> 00:01:26.100
 attended astronomy camp,
 
 00:01:26.133 --> 00:01:27.933
 and invented
 my own constellations
 
 00:01:27.967 --> 00:01:30.633
 from the stars
 above my parents\' old barn.
 
 00:01:37.800 --> 00:01:38.933
 I\'d never stopped to wonder
 
 00:01:38.967 --> 00:01:42.600
 what those dark, starry nights
 meant to me.
 
 00:01:42.633 --> 00:01:44.767
 But when I moved to the city,
 
 00:01:44.800 --> 00:01:47.267
 I felt at once like I was
 at the center of the world
 
 00:01:47.300 --> 00:01:50.233
 under all those lights
 
 00:01:50.267 --> 00:01:53.133
 and like I\'d left
 something important behind,
 
 00:01:53.167 --> 00:01:56.467
 something I couldn\'t name.
 
 00:01:56.500 --> 00:01:59.367
 What do we lose
 when we lose the night?
 
 00:02:04.767 --> 00:02:06.233
 - I don\'t know of a civilization
 
 00:02:06.267 --> 00:02:10.233
 that didn\'t have
 some kind of mythology
 
 00:02:10.267 --> 00:02:11.900
 about the night sky.
 
 00:02:15.333 --> 00:02:16.967
 - Well, if you were near
 the end of your life
 
 00:02:17.000 --> 00:02:18.667
 and you were looking back,
 
 00:02:18.700 --> 00:02:20.733
 surely, one of the things
 you\'d ask yourself is,
 
 00:02:20.767 --> 00:02:22.333
 \"Did I see the world?\"
 
 00:02:22.367 --> 00:02:25.733
 And what\'s out there in the sky,
 that\'s the ultimate horizon.
 
 00:02:25.767 --> 00:02:27.333
 That\'s as far as you can go.
 
 00:02:31.733 --> 00:02:37.033
 - I worry that our
 lack of contact with the sky
 
 00:02:37.067 --> 00:02:39.633
 is doing something to us
 that\'s very subtle.
 
 00:02:49.700 --> 00:02:52.700
 [ferry horn blaring]
 
 00:02:58.533 --> 00:03:00.800
 - A lot of people
 don\'t know much about the sky
 
 00:03:00.833 --> 00:03:02.300
 \'cause there\'s all these
 kinds of weird phenomena.
 
 00:03:02.333 --> 00:03:03.967
 That\'s why there
 are so many UFOs around,
 
 00:03:04.000 --> 00:03:05.967
 \'cause there are a lot
 of crazy people around too.
 
 00:03:06.000 --> 00:03:09.633
 But they see a light
 moving around or a meteor
 
 00:03:09.667 --> 00:03:10.667
 they never seen a meteor
 
 00:03:10.700 --> 00:03:12.100
 they call it UFO, you know?
 
 00:03:12.133 --> 00:03:13.567
 In a sense, to them, it\'s a UFO,
 
 00:03:13.600 --> 00:03:15.567
 because they\'re not used
 to looking at the sky,
 
 00:03:15.600 --> 00:03:18.067
 and if they do look at the sky
 and do catch something,
 
 00:03:18.100 --> 00:03:20.067
 they don\'t understand
 what it\'s all about
 
 00:03:20.100 --> 00:03:22.400
 most people, most people.
 
 00:03:22.433 --> 00:03:24.233
 But, you know,
 Americans are not known
 
 00:03:24.267 --> 00:03:27.767
 for their knowledge, you know?
 
 00:03:33.900 --> 00:03:36.533
 - Professor Irving Robbins
 is an astronomer
 
 00:03:36.567 --> 00:03:38.800
 who runs one of the last
 remaining observatories
 
 00:03:38.833 --> 00:03:40.467
 in New York City.
 
 00:03:40.500 --> 00:03:42.140
 - Welcome to the College
 of Staten Island,
 
 00:03:42.167 --> 00:03:43.467
 located on Staten Island,
 
 00:03:43.500 --> 00:03:44.967
 which is one
 of the five boroughs
 
 00:03:45.000 --> 00:03:46.333
 of the city of New York.
 
 00:03:46.367 --> 00:03:48.333
 Of course, Staten Island
 is in the United States
 
 00:03:48.367 --> 00:03:49.633
 on planet Earth, so welcome.
 
 00:03:49.667 --> 00:03:50.667
 [clanking and whirring]
 
 00:03:50.700 --> 00:03:51.800
 There she goes.
 
 00:03:55.033 --> 00:03:58.667
 I\'ve seen twice
 the Milky Way in New York,
 
 00:03:58.700 --> 00:04:00.733
 when there was the blackouts.
 
 00:04:00.767 --> 00:04:02.567
 In 1966, I was in Brooklyn.
 
 00:04:02.600 --> 00:04:04.733
 I was working
 in Bedford-Stuyvesant.
 
 00:04:04.767 --> 00:04:07.400
 Lights all went out,
 and there I was;
 
 00:04:07.433 --> 00:04:08.733
 I could not believe the heavens.
 
 00:04:08.767 --> 00:04:10.067
 It was like on the deserts.
 
 00:04:10.100 --> 00:04:12.067
 I mean, all
 the whole Northeast went out,
 
 00:04:12.100 --> 00:04:14.733
 and the sky was spectacular,
 just beautiful.
 
 00:04:14.767 --> 00:04:16.267
 It was really beautiful.
 
 00:04:16.300 --> 00:04:17.433
 As you know, in New York,
 
 00:04:17.467 --> 00:04:19.100
 there is a light pollution
 problem.
 
 00:04:19.133 --> 00:04:22.267
 We\'re limited to how far deep
 in space we can go
 
 00:04:22.300 --> 00:04:25.367
 because of the light pollution.
 
 00:04:25.400 --> 00:04:27.867
 When you look at the sky,
 the sky
 
 00:04:27.900 --> 00:04:30.633
 the light in the sky
 really is the sum total
 
 00:04:30.667 --> 00:04:32.633
 of everything around you.
 
 00:04:32.667 --> 00:04:35.467
 It\'s like I have
 a beautiful painting, right?
 
 00:04:35.500 --> 00:04:37.633
 Very nice, but now I come along
 with an eraser,
 
 00:04:37.667 --> 00:04:40.967
 and I erase all of it
 and just leave a few spots.
 
 00:04:41.000 --> 00:04:43.667
 That\'s what
 light pollution does.
 
 00:04:52.633 --> 00:04:55.900
 - What astronomers call
 light pollution
 
 00:04:55.933 --> 00:04:58.300
 occurs when lights
 shining upward
 
 00:04:58.333 --> 00:05:00.900
 bounce off dust
 and particulates in the air,
 
 00:05:00.933 --> 00:05:03.267
 causing the very sky to glow.
 
 00:05:07.167 --> 00:05:08.800
 To live in New York these days
 
 00:05:08.833 --> 00:05:15.100
 is to live under
 a kind of illuminated tent.
 
 00:05:15.133 --> 00:05:17.500
 But it wasn\'t always.
 
 00:05:17.533 --> 00:05:22.900
 In the past, people used stars
 to navigate the seas.
 
 00:05:22.933 --> 00:05:26.567
 Ancient constellations
 like Orion the Hunter
 
 00:05:26.600 --> 00:05:29.567
 were later joined
 by more modern inventions
 
 00:05:29.600 --> 00:05:32.767
 like compass and the telescope.
 
 00:05:35.400 --> 00:05:36.800
 On the Earth below,
 
 00:05:36.833 --> 00:05:38.633
 the only lights
 for thousands of years
 
 00:05:38.667 --> 00:05:43.467
 were crude torches, campfires,
 and candles.
 
 00:05:43.500 --> 00:05:45.967
 By the 17th and 18th centuries,
 
 00:05:46.000 --> 00:05:50.533
 oil lamps powered by whale oil
 illuminated Manhattan.
 
 00:05:50.567 --> 00:05:54.600
 In the early 1800s,
 gas lighting was introduced.
 
 00:05:56.833 --> 00:05:59.467
 And finally,
 in the late 19th century,
 
 00:05:59.500 --> 00:06:02.067
 a new form of lighting emerged.
 
 00:06:04.700 --> 00:06:07.500
 - It has been said,
 correctly, I think,
 
 00:06:07.533 --> 00:06:12.467
 that there is no better symbol
 
 00:06:12.500 --> 00:06:16.500
 of modern progress
 
 00:06:16.533 --> 00:06:22.333
 than the advent of electricity
 in general
 
 00:06:22.367 --> 00:06:26.333
 but electric lighting
 in particular.
 
 00:06:41.667 --> 00:06:44.667
 [doorbell ringing]
 
 00:06:49.233 --> 00:06:51.533
 - This doesn\'t bother me.
 
 00:06:51.567 --> 00:06:53.700
 Bothers a lot of people, though.
 
 00:06:53.733 --> 00:06:56.033
 Hey, you want to see the
 I tell people you
 
 00:06:56.067 --> 00:06:59.500
 if you came into a light store
 that looked like that,
 
 00:06:59.533 --> 00:07:02.400
 wouldn\'t you wonder, you know,
 
 00:07:02.433 --> 00:07:04.733
 what kind of place it is?
 
 00:07:04.767 --> 00:07:06.867
 [man speaking indistinctly]
 
 00:07:06.900 --> 00:07:10.033
 [door creaks open]
 
 00:07:10.067 --> 00:07:14.533
 About 75,000 lightbulbs
 back here, approximately,
 
 00:07:14.567 --> 00:07:16.700
 different types.
 
 00:07:16.733 --> 00:07:20.200
 There was my father
 who was in the business,
 
 00:07:20.233 --> 00:07:23.500
 and my grandfather
 was also in the business,
 
 00:07:23.533 --> 00:07:27.167
 and he knew Edison.
 
 00:07:27.200 --> 00:07:29.333
 My grandfather was an inventor.
 
 00:07:29.367 --> 00:07:33.667
 So he, you know, was friendly
 with Thomas Edison,
 
 00:07:33.700 --> 00:07:38.567
 and my grandfather was there
 when things started.
 
 00:07:38.600 --> 00:07:44.567
 This one is an original
 Edison lightbulb,
 
 00:07:44.600 --> 00:07:47.567
 and these still actually work.
 
 00:07:48.833 --> 00:07:51.967
 [electricity whirring faintly]
 
 00:07:52.000 --> 00:07:55.933
 1879 was the first lightbulb.
 
 00:07:59.333 --> 00:08:01.367
 More light.
 
 00:08:01.400 --> 00:08:05.833
 As you went up in generations,
 
 00:08:05.867 --> 00:08:08.167
 the brightness increased.
 
 00:08:08.200 --> 00:08:12.667
 They were trying to maximize
 the amount of light.
 
 00:08:12.700 --> 00:08:16.133
 Self-ballasted
 mercury vapor.
 
 00:08:16.167 --> 00:08:19.433
 Then they came out
 with high-pressure sodium,
 
 00:08:19.467 --> 00:08:22.433
 which was a yellowish light,
 
 00:08:22.467 --> 00:08:26.233
 and that one
 gets even brighter than this.
 
 00:08:26.267 --> 00:08:29.900
 And then they came out
 with the metal halide.
 
 00:08:29.933 --> 00:08:32.733
 That\'s this.
 
 00:08:32.767 --> 00:08:35.733
 That one,
 you could cook a meal on that.
 
 00:08:35.767 --> 00:08:38.733
 That\'s how hot this one gets.
 
 00:08:38.767 --> 00:08:40.400
 You look at this after,
 
 00:08:40.433 --> 00:08:43.233
 and you won\'t be able
 to see for a while.
 
 00:08:43.267 --> 00:08:44.867
 [magnet clicks]
 
 00:08:44.900 --> 00:08:47.967
 Believe me, today I see stuff,
 
 00:08:48.000 --> 00:08:50.000
 new stuff that\'s coming out,
 it\'s like, wow.
 
 00:08:51.767 --> 00:08:54.067
 - Today\'s lights
 are capable of producing
 
 00:08:54.100 --> 00:08:55.667
 thousands more lumens
 
 00:08:55.700 --> 00:08:57.767
 than Edison\'s original
 lightbulb.
 
 00:09:00.600 --> 00:09:05.200
 The mercury vapor light is
 popular on barns and warehouses.
 
 00:09:05.233 --> 00:09:08.300
 The metal halide often
 illuminates car dealerships.
 
 00:09:08.333 --> 00:09:10.467
 And high-pressure
 sodium lights
 
 00:09:10.500 --> 00:09:12.633
 are found on cobra head
 light fixtures
 
 00:09:12.667 --> 00:09:15.633
 all across the country.
 
 00:09:15.667 --> 00:09:18.600
 As electric lights grew brighter
 and more numerous
 
 00:09:18.633 --> 00:09:20.600
 throughout the 20th century,
 
 00:09:20.633 --> 00:09:23.267
 the starlight
 above America\'s cities
 
 00:09:23.300 --> 00:09:25.333
 tended to go the other way.
 
 00:09:36.467 --> 00:09:38.767
 - As I\'ve gotten older,
 
 00:09:38.800 --> 00:09:40.867
 I notice I have to go
 farther and farther
 
 00:09:40.900 --> 00:09:43.367
 from wherever
 there\'s any civilization
 
 00:09:43.400 --> 00:09:47.333
 in order to see the sky,
 to be part of the universe.
 
 00:09:47.367 --> 00:09:50.667
 I began to do
 all of my observing
 
 00:09:50.700 --> 00:09:55.833
 from down at Jones Beach,
 which, in 1973,
 
 00:09:55.867 --> 00:09:58.733
 was still reasonably dark.
 
 00:09:58.767 --> 00:10:04.033
 Unfortunately, night no longer
 comes to Jones Beach.
 
 00:10:06.433 --> 00:10:08.400
 We would use this area
 right here
 
 00:10:08.433 --> 00:10:10.400
 and just unload our scopes,
 
 00:10:10.433 --> 00:10:13.400
 and this whole area
 would be filled with scopes,
 
 00:10:13.433 --> 00:10:15.733
 and the phone is still there.
 
 00:10:15.767 --> 00:10:17.733
 I bet you can\'t find the number.
 
 00:10:17.767 --> 00:10:21.233
 Ah, yes. 785-9743.
 
 00:10:21.267 --> 00:10:22.400
 The number didn\'t change.
 
 00:10:22.433 --> 00:10:24.033
 [laughs]
 
 00:10:24.067 --> 00:10:26.533
 Pretty much, no matter
 which side you went from,
 
 00:10:26.567 --> 00:10:28.033
 there were
 telescopes everywhere.
 
 00:10:28.067 --> 00:10:32.700
 This now, there isn\'t even
 a handle to get in here.
 
 00:10:32.733 --> 00:10:34.567
 I wonder what they do.
 
 00:10:36.167 --> 00:10:39.400
 We determined the length
 of an asteroid from here.
 
 00:10:39.433 --> 00:10:43.733
 We measured some double stars
 from here.
 
 00:10:43.767 --> 00:10:45.400
 Depending on the season
 of the year,
 
 00:10:45.433 --> 00:10:47.900
 it might be Orion in the winter
 
 00:10:47.933 --> 00:10:50.900
 or Scorpius and Sagittarius
 in the summer,
 
 00:10:50.933 --> 00:10:54.933
 with the Milky Way coming up
 like the steam from the teapot.
 
 00:10:56.867 --> 00:10:59.200
 Great place to be.
 
 00:11:06.500 --> 00:11:08.800
 Already, Jupiter\'s coming out,
 
 00:11:08.833 --> 00:11:10.533
 biggest planet
 in the solar system,
 
 00:11:10.567 --> 00:11:12.867
 second biggest object.
 
 00:11:12.900 --> 00:11:14.733
 That\'s just the teaser.
 
 00:11:16.067 --> 00:11:20.033
 It\'s so sad because
 I know what\'s above me
 
 00:11:20.067 --> 00:11:21.367
 once it gets dark here.
 
 00:11:21.400 --> 00:11:23.900
 It just doesn\'t get dark
 anymore.
 
 00:11:28.667 --> 00:11:30.067
 - Cities have always been
 
 00:11:30.100 --> 00:11:32.567
 kind of overburdened
 with lights.
 
 00:11:32.600 --> 00:11:35.400
 I think you\'re allowed to have
 some expectation, though,
 
 00:11:35.433 --> 00:11:37.233
 that when you leave the city
 
 00:11:37.267 --> 00:11:40.067
 ten miles, fifty miles,
 a hundred miles
 
 00:11:40.100 --> 00:11:43.667
 that the sky should start
 to come back to you.
 
 00:11:46.967 --> 00:11:49.967
 [indistinct speech on radio]
 
 00:12:12.900 --> 00:12:14.900
 [clanking]
 
 00:12:16.567 --> 00:12:18.367
 - Well, it\'s pretty dark.
 
 00:12:18.400 --> 00:12:19.900
 [muffled clanking]
 
 00:12:24.600 --> 00:12:27.600
 [camera clicks]
 
 00:12:29.933 --> 00:12:32.933
 [camera clicks]
 
 00:12:56.733 --> 00:12:59.400
 - I was born and raised
 in the Bronx, New York,
 
 00:12:59.433 --> 00:13:02.300
 in an apartment complex
 
 00:13:02.333 --> 00:13:06.133
 prophetically called
 the Skyview Apartments.
 
 00:13:06.167 --> 00:13:08.000
 And what happened
 when I was nine
 
 00:13:08.033 --> 00:13:11.167
 was that first visit
 to the Hayden Planetarium
 
 00:13:11.200 --> 00:13:13.167
 here in New York City.
 
 00:13:13.200 --> 00:13:16.000
 There you are in this room,
 this odd-shaped room.
 
 00:13:16.033 --> 00:13:18.000
 It\'s round,
 and it\'s got a round ceiling,
 
 00:13:18.033 --> 00:13:20.633
 and they turn off the lights.
 
 00:13:20.667 --> 00:13:23.633
 They even have permission
 to turn off the exit lights,
 
 00:13:23.667 --> 00:13:25.133
 so it\'s comp you can\'t even see
 
 00:13:25.167 --> 00:13:26.967
 the hand in front of your face.
 
 00:13:27.000 --> 00:13:31.300
 And the stars come out,
 and I was sure it was a hoax.
 
 00:13:31.333 --> 00:13:32.967
 I\'ve seen the night sky
 from the Bronx.
 
 00:13:33.000 --> 00:13:34.467
 There\'s a dozen stars there,
 
 00:13:34.500 --> 00:13:36.967
 and there were way too many
 stars in the Hayden Planetarium
 
 00:13:37.000 --> 00:13:39.133
 for me to believe it.
 
 00:13:39.167 --> 00:13:41.633
 And it would take several years
 before I recognized that,
 
 00:13:41.667 --> 00:13:46.500
 in fact, this was an accurate
 capturing of the night sky.
 
 00:13:48.167 --> 00:13:49.800
 And to this day,
 I\'m on mountaintops,
 
 00:13:49.833 --> 00:13:51.467
 and I look up,
 
 00:13:51.500 --> 00:13:52.633
 and I say to my
 
 00:13:52.667 --> 00:13:54.633
 this is a sickeningly urban
 thing to say,
 
 00:13:54.667 --> 00:13:56.300
 but I look up, and I say,
 
 00:13:56.333 --> 00:13:58.633
 \"Reminds me
 of the Hayden Planetarium.\"
 
 00:13:58.667 --> 00:14:00.567
 [laughs]
 You know...
 
 00:14:06.500 --> 00:14:09.467
 - You know, we\'re nothing
 if we\'re not adaptive,
 
 00:14:09.500 --> 00:14:13.300
 and so as we adapt
 to these deprivations
 
 00:14:13.333 --> 00:14:14.967
 of not seeing the sky,
 
 00:14:15.000 --> 00:14:19.267
 we create mechanisms
 to mimic them.
 
 00:14:19.300 --> 00:14:23.300
 Who knows what
 the ultimate effect will be?
 
 00:14:42.800 --> 00:14:44.333
 [plastic rattling]
 
 00:15:23.933 --> 00:15:25.900
 - What\'s happened
 over my lifetime is that
 
 00:15:25.933 --> 00:15:30.233
 you have kind of a sprawl
 with the city lights.
 
 00:15:30.267 --> 00:15:32.967
 [car horn honking]
 
 00:15:33.000 --> 00:15:34.133
 Perhaps in the old days,
 
 00:15:34.167 --> 00:15:36.800
 it was just homes
 with streetlights,
 
 00:15:36.833 --> 00:15:40.633
 and now it\'s homes
 near shopping malls,
 
 00:15:40.667 --> 00:15:42.967
 fully lit parking lots,
 
 00:15:43.000 --> 00:15:46.300
 each of which has its own lights
 
 00:15:46.333 --> 00:15:49.333
 spilling out
 into the surrounding regions.
 
 00:15:55.733 --> 00:15:59.000
 - Our society is kind of
 taking over the wilderness,
 
 00:15:59.033 --> 00:16:02.600
 but it\'s happening slowly,
 and no one really notices it.
 
 00:16:04.933 --> 00:16:09.100
 Now the sky is just
 impossibly bright.
 
 00:16:11.400 --> 00:16:12.700
 And so the astronomers
 
 00:16:12.733 --> 00:16:15.700
 have had to flee
 the population centers
 
 00:16:15.733 --> 00:16:18.567
 and move to the desert
 and island areas of the world.
 
 00:16:41.000 --> 00:16:42.300
 - We\'re right on the border
 
 00:16:42.333 --> 00:16:46.067
 between eastern Arizona
 and New Mexico.
 
 00:16:46.100 --> 00:16:51.233
 - The closest grocery store
 is a little over an hour,
 
 00:16:51.267 --> 00:16:53.733
 and that\'s in Douglas
 on the border.
 
 00:16:53.767 --> 00:16:55.867
 This is one of the few regions
 
 00:16:55.900 --> 00:16:59.167
 that still has really good
 dark skies.
 
 00:17:07.500 --> 00:17:09.900
 - The town of Sky Village
 was created
 
 00:17:09.933 --> 00:17:11.833
 by a man named Jack Newton,
 
 00:17:11.867 --> 00:17:14.167
 one of my childhood heroes
 
 00:17:14.200 --> 00:17:15.867
 and widely considered to be
 
 00:17:15.900 --> 00:17:19.833
 one of the greatest
 astrophotographers of our time.
 
 00:17:19.867 --> 00:17:23.700
 - We hunted diligently for
 dark skies to find this site,
 
 00:17:23.733 --> 00:17:26.700
 the darkest spot
 in southwestern U.S.,
 
 00:17:26.733 --> 00:17:28.700
 and that was Portal, Arizona.
 
 00:17:28.733 --> 00:17:31.700
 And then we were able
 to collect 450 acres
 
 00:17:31.733 --> 00:17:35.200
 and set up the Arizona
 Sky Village for astronomers,
 
 00:17:35.233 --> 00:17:36.800
 and it\'s been magnificent.
 
 00:17:36.833 --> 00:17:39.833
 [whirring]
 
 00:17:42.867 --> 00:17:47.667
 My primary instrument here
 is a 20-inch telescope
 
 00:17:47.700 --> 00:17:49.600
 with a carbon fiber tube.
 
 00:17:49.633 --> 00:17:52.267
 - I have a Meade 16-inch
 Schmidt-Cassegrain telescope
 
 00:17:52.300 --> 00:17:54.133
 as the primary instrument
 in there.
 
 00:17:54.167 --> 00:17:57.133
 - This is a H-alpha
 solar telescope.
 
 00:17:57.167 --> 00:17:58.467
 - It carries piggyback
 
 00:17:58.500 --> 00:18:02.200
 a Takahashi 180 Epsilon
 Astrograph
 
 00:18:02.233 --> 00:18:03.900
 high-speed camera lens.
 
 00:18:03.933 --> 00:18:06.400
 - This is the observatory
 we\'re having built here.
 
 00:18:06.433 --> 00:18:08.233
 The telescope mount
 will be here,
 
 00:18:08.267 --> 00:18:10.600
 and we\'ll have a 10-foot dome
 above us here.
 
 00:18:10.633 --> 00:18:13.567
 - So we chase
 total solar eclipses.
 
 00:18:13.600 --> 00:18:15.900
 - It\'s paradise
 for an astrophotographer
 
 00:18:15.933 --> 00:18:17.433
 to be out here.
 
 00:18:17.467 --> 00:18:19.600
 - We all come from different
 walks of life,
 
 00:18:19.633 --> 00:18:22.533
 but we have all moved here
 with one thing in common.
 
 00:18:22.567 --> 00:18:24.200
 We all love the night sky.
 
 00:18:24.233 --> 00:18:26.867
 [whirring]
 
 00:18:26.900 --> 00:18:29.367
 This is my clubhouse.
 
 00:18:29.400 --> 00:18:31.700
 Every guy wants a clubhouse
 when he grows up,
 
 00:18:31.733 --> 00:18:33.033
 and this is it.
 
 00:18:33.067 --> 00:18:34.400
 I call my observatory
 
 00:18:34.433 --> 00:18:36.533
 Conferring With the Sky
 Observatory.
 
 00:18:36.567 --> 00:18:37.967
 [dogs barking]
 
 00:18:39.533 --> 00:18:42.267
 - I was shooting last night,
 
 00:18:42.300 --> 00:18:47.000
 and there\'s the spiral galaxy.
 
 00:18:47.033 --> 00:18:51.833
 This one is 57 million
 light-years away.
 
 00:18:51.867 --> 00:18:54.533
 So the light
 left 57 million years ago.
 
 00:18:54.567 --> 00:18:58.333
 This is called
 the North America Nebula.
 
 00:18:58.367 --> 00:19:00.900
 This is called
 the Heart and the Soul,
 
 00:19:00.933 --> 00:19:03.300
 this being the Heart
 and that being the Soul.
 
 00:19:03.333 --> 00:19:06.633
 This is Orion\'s Belt,
 the three stars in the belt.
 
 00:19:06.667 --> 00:19:09.933
 This is the dagger that
 hangs down from Orion\'s Belt.
 
 00:19:11.300 --> 00:19:16.267
 I would go nuts if I couldn\'t
 have the dark night sky.
 
 00:19:16.300 --> 00:19:19.267
 There\'s a whole universe
 out there.
 
 00:19:27.967 --> 00:19:30.967
 [footsteps crunching on gravel]
 
 00:19:38.100 --> 00:19:39.400
 [camera clicks]
 
 00:19:39.433 --> 00:19:42.033
 [mellow instrumental music]
 
 00:19:42.067 --> 00:19:43.867
 - The Milky Way,
 when it rises here,
 
 00:19:43.900 --> 00:19:46.367
 looks like a thunderstorm
 coming toward you,
 
 00:19:46.400 --> 00:19:48.533
 and you think, \"Oh, my God,
 it\'s gonna cloud over.\"
 
 00:19:48.567 --> 00:19:49.700
 And it\'s not.
 
 00:19:49.733 --> 00:19:51.033
 It\'s the Milky Way rising.
 
 00:19:51.067 --> 00:19:53.400
 It\'s the edge of our galaxy
 coming up.
 
 00:20:14.667 --> 00:20:17.467
 - Being out under the stars
 at night,
 
 00:20:17.500 --> 00:20:20.800
 I was reminded of the scale
 of our world,
 
 00:20:20.833 --> 00:20:23.600
 a scale that\'s all too easy
 to forget
 
 00:20:23.633 --> 00:20:26.633
 when you don\'t have this clear
 a view of the skies above.
 
 00:20:31.067 --> 00:20:34.800
 - If we didn\'t have a good view
 of a dark sky,
 
 00:20:34.833 --> 00:20:37.867
 we wouldn\'t know we lived
 in a galaxy like the Milky Way.
 
 00:20:37.900 --> 00:20:39.033
 We wouldn\'t know that
 
 00:20:39.067 --> 00:20:41.700
 the universe
 was 50 billion galaxies,
 
 00:20:41.733 --> 00:20:44.500
 each with hundreds of billions
 of stars.
 
 00:20:44.533 --> 00:20:47.600
 We would know very little
 about the universe we lived in.
 
 00:20:49.000 --> 00:20:51.800
 Once you\'ve known
 what a truly dark sky is
 
 00:20:51.833 --> 00:20:54.633
 once I observed
 the observatories in Hawaii,
 
 00:20:54.667 --> 00:20:56.300
 which, to me,
 are the gold standard
 
 00:20:56.333 --> 00:20:59.133
 it\'s like once you\'ve [...]
 the very best kind of [...]
 
 00:20:59.167 --> 00:21:00.967
 or had the very best
 single malt [...],
 
 00:21:01.000 --> 00:21:03.000
 you know,
 you can\'t really go back.
 
 00:21:12.933 --> 00:21:15.067
 - Astronomy is the oldest
 of the sciences.
 
 00:21:15.100 --> 00:21:16.233
 We can go back,
 
 00:21:16.267 --> 00:21:18.067
 and we can trace the development
 
 00:21:18.100 --> 00:21:20.567
 of our inquiry into the universe
 
 00:21:20.600 --> 00:21:22.900
 to the ability
 to look up to the sky
 
 00:21:22.933 --> 00:21:24.733
 to see things
 that you don\'t understand
 
 00:21:24.767 --> 00:21:27.233
 that you want to be able
 to touch and understand.
 
 00:21:27.267 --> 00:21:29.733
 Every civilization
 that we know about
 
 00:21:29.767 --> 00:21:32.333
 built a science
 around explaining
 
 00:21:32.367 --> 00:21:35.033
 the sky that was above them
 that they saw at night.
 
 00:21:36.567 --> 00:21:38.700
 - We\'re going to a place
 called Science City.
 
 00:21:38.733 --> 00:21:40.867
 - Ladies and gentlemen,
 we\'ll be landing very shortly.
 
 00:21:40.900 --> 00:21:43.200
 Please make sure your seat belts
 are securely fastened.
 
 00:21:43.233 --> 00:21:44.700
 Mahalo.
 
 00:21:44.733 --> 00:21:48.200
 - It\'s literally true that
 there is no better place in
 
 00:21:48.233 --> 00:21:51.867
 on this planet to observe
 than the Hawaiian Islands.
 
 00:21:55.700 --> 00:21:57.833
 - The volcanic islands of Hawaii
 
 00:21:57.867 --> 00:21:59.700
 thrust up
 out of the Pacific Ocean
 
 00:21:59.733 --> 00:22:01.467
 and all the way
 through the clouds,
 
 00:22:01.500 --> 00:22:04.867
 giving astronomers
 clear air and clear skies.
 
 00:22:07.300 --> 00:22:10.767
 On Mauna Kea, some of
 the world\'s largest telescopes
 
 00:22:10.800 --> 00:22:15.433
 scan the sky from an altitude
 of 14,000 feet.
 
 00:22:15.467 --> 00:22:19.567
 And on Haleakala, astronomers
 have recently built a telescope
 
 00:22:19.600 --> 00:22:21.233
 that they describe
 as the largest,
 
 00:22:21.267 --> 00:22:24.167
 most light-sensitive camera
 in history.
 
 00:22:26.800 --> 00:22:29.933
 - This is the
 Pan-STARRS 1.8-meter telescope.
 
 00:22:29.967 --> 00:22:32.933
 Its detectors span an area
 like this
 
 00:22:32.967 --> 00:22:35.933
 behind this plate
 inside the vacuum.
 
 00:22:35.967 --> 00:22:39.067
 One of the primary reasons
 for building this thing is,
 
 00:22:39.100 --> 00:22:40.933
 we want to find
 killer asteroids.
 
 00:22:43.933 --> 00:22:47.733
 - Well, the Earth is being
 hit by stuff all the time.
 
 00:22:47.767 --> 00:22:49.567
 The biggest threat
 is from objects
 
 00:22:49.600 --> 00:22:52.900
 that are about a kilometer
 in size or more.
 
 00:22:52.933 --> 00:22:56.567
 And if one of those objects
 hits the Earth,
 
 00:22:56.600 --> 00:22:59.967
 then it produces
 a global catastrophe,
 
 00:23:00.067 --> 00:23:03.033
 something like
 many thousands of H-bombs
 
 00:23:03.067 --> 00:23:05.733
 going off instantaneously.
 
 00:23:08.533 --> 00:23:11.800
 - Detecting asteroids,
 which are small and dark,
 
 00:23:11.833 --> 00:23:14.267
 depends on having
 extremely dark skies,
 
 00:23:14.300 --> 00:23:18.533
 which, even on Hawaii,
 are threatened by development.
 
 00:23:18.567 --> 00:23:21.667
 But I got the sense
 that astronomers were worried
 
 00:23:21.700 --> 00:23:23.767
 about a much deeper loss,
 
 00:23:23.800 --> 00:23:25.933
 one tied
 to their ancient profession
 
 00:23:25.967 --> 00:23:28.633
 of decoding the universe above.
 
 00:23:31.800 --> 00:23:33.433
 Seeing the universe around us
 
 00:23:33.467 --> 00:23:35.600
 tells us about our own part
 of the universe,
 
 00:23:35.633 --> 00:23:37.767
 and to close that door, I think,
 
 00:23:37.800 --> 00:23:42.467
 would change the character
 of humankind entirely.
 
 00:23:46.767 --> 00:23:49.067
 A team of Italian cartographers,
 
 00:23:49.100 --> 00:23:51.900
 piecing together a map
 of the Earth at night,
 
 00:23:51.933 --> 00:23:55.567
 concluded that 2/3 of all humans
 now live under skies
 
 00:23:55.600 --> 00:23:58.567
 polluted by artificial light.
 
 00:23:58.600 --> 00:24:00.967
 As they put it,
 \"Mankind is proceeding
 
 00:24:01.000 --> 00:24:04.500
 to envelop themself
 in a luminous fog.\"
 
 00:24:55.433 --> 00:24:58.400
 [thunder rumbling]
 
 00:24:58.433 --> 00:25:01.500
 [waves crashing]
 
 00:25:23.433 --> 00:25:24.767
 [rattling]
 
 00:25:24.800 --> 00:25:27.467
 [engine whines and rumbles]
 
 00:25:43.033 --> 00:25:44.333
 - We\'re just heading north,
 
 00:25:44.367 --> 00:25:49.833
 basically to our northern border
 with Highland Beach,
 
 00:25:49.867 --> 00:25:52.767
 and actually, from here,
 you can already see
 
 00:25:52.800 --> 00:25:57.100
 the amount of sky glow
 we get from that area.
 
 00:25:57.133 --> 00:26:01.033
 The glow looking in that
 direction is really intense.
 
 00:26:03.433 --> 00:26:05.900
 - Every summer,
 along the Florida coast,
 
 00:26:05.933 --> 00:26:09.400
 thousands of hatching
 sea turtles emerge from the sand
 
 00:26:09.433 --> 00:26:12.433
 and struggle to find their way
 to the sea.
 
 00:26:12.467 --> 00:26:14.600
 - For about
 the last 200 million years,
 
 00:26:14.633 --> 00:26:18.433
 sea turtles have utilized
 the beaches in Florida
 
 00:26:18.467 --> 00:26:20.233
 as their nesting grounds.
 
 00:26:20.267 --> 00:26:23.733
 Over that time period,
 in a dark world,
 
 00:26:23.767 --> 00:26:27.433
 the sea turtles had learned
 that the water was located
 
 00:26:27.467 --> 00:26:30.500
 on the lightest horizon,
 because the ocean,
 
 00:26:30.533 --> 00:26:33.667
 the waters would reflect
 starlight.
 
 00:26:33.700 --> 00:26:37.333
 In the last 100 years or so
 in Florida, obviously,
 
 00:26:37.367 --> 00:26:40.833
 the lighting situation
 has changed dramatically.
 
 00:26:40.867 --> 00:26:43.000
 Instead of going towards
 the water,
 
 00:26:43.033 --> 00:26:45.700
 they go to the brighter light.
 
 00:26:55.333 --> 00:26:58.333
 [waves crashing]
 
 00:27:01.833 --> 00:27:05.133
 - Biologists use
 infrared camera lights
 
 00:27:05.167 --> 00:27:07.800
 to avoid disorienting
 the turtles,
 
 00:27:07.833 --> 00:27:10.633
 because when the hatchlings
 emerge from their nests,
 
 00:27:10.667 --> 00:27:13.833
 they have only a matter
 of minutes to make it to the sea
 
 00:27:13.867 --> 00:27:17.233
 before they grow dehydrated
 or fall victim to predators.
 
 00:27:47.133 --> 00:27:53.133
 [upbeat music]
 
 00:28:37.800 --> 00:28:39.467
 - Nice!
 
 00:29:12.333 --> 00:29:14.467
 - We made sure
 all the hatchlings we saw
 
 00:29:14.500 --> 00:29:16.800
 made it to the water.
 
 00:29:16.833 --> 00:29:19.967
 But every summer,
 tens of thousands of turtles,
 
 00:29:20.000 --> 00:29:24.500
 already a threatened species,
 are lost to disorientation.
 
 00:29:34.500 --> 00:29:37.467
 I began to think
 about disorientation,
 
 00:29:37.500 --> 00:29:41.100
 about the way I try to orient
 myself on an airplane at night,
 
 00:29:41.133 --> 00:29:43.267
 not using the stars
 
 00:29:43.300 --> 00:29:47.767
 but using the constellations
 of cities glowing below.
 
 00:29:47.800 --> 00:29:49.767
 Like someone has taken
 the night sky
 
 00:29:49.800 --> 00:29:51.967
 and flipped it upside down,
 
 00:29:52.000 --> 00:29:54.600
 so that flying between
 stars and cities,
 
 00:29:54.633 --> 00:29:57.933
 you could understand how,
 if only for a moment,
 
 00:29:57.967 --> 00:30:00.433
 you might forget
 which was which.
 
 00:30:06.467 --> 00:30:08.433
 [phone rings]
 
 00:30:08.467 --> 00:30:12.100
 - Chicago Bird Collision
 Monitors.
 
 00:30:12.133 --> 00:30:15.300
 10 South Riverside.
 Do you have a bird there?
 
 00:30:18.100 --> 00:30:21.900
 We find about an average
 of 4,000 birds a year
 
 00:30:21.933 --> 00:30:24.033
 in our spring
 and fall migration combined.
 
 00:30:24.067 --> 00:30:27.367
 That\'s 4,000, you know,
 both dead and injured combined.
 
 00:30:27.400 --> 00:30:29.533
 And we know that
 we\'re not finding everything.
 
 00:30:29.567 --> 00:30:30.633
 - He\'s movin\'.
 
 00:30:30.667 --> 00:30:31.767
 - Oh, that\'s nice.
 
 00:30:31.800 --> 00:30:33.267
 - I found him right over here
 by my car.
 
 00:30:33.300 --> 00:30:35.633
 - Wonderful.
 Okay.
 
 00:30:37.100 --> 00:30:38.733
 Whoa, whoa, whoa.
 
 00:30:38.767 --> 00:30:40.067
 Where is he?
 
 00:30:40.100 --> 00:30:41.833
 Oh, it\'s another sapsucker.
 Look at this.
 
 00:30:41.867 --> 00:30:43.400
 - Oh, that\'s what that is?
 A sapsucker.
 
 00:30:43.433 --> 00:30:46.400
 - It\'s a woodpecker.
 It\'s a yellow-bellied sapsucker.
 
 00:30:46.433 --> 00:30:48.733
 - Oh, it is.
 Okay, I just
 
 00:30:48.767 --> 00:30:50.600
 Oh, good, he\'s oh, great.
 
 00:30:50.633 --> 00:30:54.267
 So he must have hit this
 building or something and...
 
 00:30:54.300 --> 00:30:55.933
 I just seen him breathing,
 
 00:30:55.967 --> 00:31:00.167
 so I had my co-worker
 come out with a towel.
 
 00:31:00.200 --> 00:31:01.667
 I\'ve used her quite a few times.
 
 00:31:01.700 --> 00:31:03.333
 I\'m glad I got her number, so...
 
 00:31:03.367 --> 00:31:05.167
 - That\'s great.
 
 00:31:05.200 --> 00:31:08.833
 - And this is a case where
 you kind of got to move fast
 
 00:31:08.867 --> 00:31:11.333
 in case there\'s a gull
 that\'s gonna spot him,
 
 00:31:11.367 --> 00:31:12.500
 \'cause he\'s in a place
 
 00:31:12.533 --> 00:31:14.700
 where there\'s a lot of crows
 and gulls.
 
 00:31:19.100 --> 00:31:21.900
 He\'s broke the top of his beak.
 
 00:31:21.933 --> 00:31:23.900
 And sometimes that can heal,
 
 00:31:23.933 --> 00:31:26.600
 but that\'s really kind of sad.
 
 00:31:37.100 --> 00:31:39.167
 - Even though
 you can\'t see them,
 
 00:31:39.200 --> 00:31:42.500
 there are thousands
 and thousands of birds
 
 00:31:42.533 --> 00:31:46.167
 flying over your head
 every night during migration.
 
 00:31:52.633 --> 00:31:54.433
 We know from early studies
 
 00:31:54.467 --> 00:31:57.767
 that the stars actually serve
 as a map for birds
 
 00:31:57.800 --> 00:32:00.600
 as they migrate
 through the night skies.
 
 00:32:06.733 --> 00:32:08.533
 - The problem
 with lights in the city
 
 00:32:08.567 --> 00:32:11.367
 is that these birds,
 which have been migrating
 
 00:32:11.400 --> 00:32:15.033
 with their star chart,
 get into the realm of a city,
 
 00:32:15.067 --> 00:32:18.067
 and suddenly, there are all of
 these artificial stars all over,
 
 00:32:18.100 --> 00:32:19.400
 the dots of windows
 
 00:32:19.433 --> 00:32:22.067
 and lights in the buildings
 of the city,
 
 00:32:22.100 --> 00:32:24.400
 and that completely disorients
 the birds.
 
 00:32:24.433 --> 00:32:27.567
 They get into these
 great canyons of buildings
 
 00:32:27.600 --> 00:32:33.600
 and then run into glass
 and end up killing themselves.
 
 00:32:36.000 --> 00:32:39.133
 - Birds are not only
 disoriented by city lights.
 
 00:32:39.167 --> 00:32:41.300
 They are drawn to them.
 
 00:32:41.333 --> 00:32:43.133
 In one study by volunteers
 
 00:32:43.167 --> 00:32:45.800
 from The Field Museum
 in Chicago,
 
 00:32:45.833 --> 00:32:47.967
 a building that shut off
 half its lights
 
 00:32:48.000 --> 00:32:50.800
 recorded a ten-fold decrease
 in bird deaths
 
 00:32:50.833 --> 00:32:53.833
 compared to the half of
 the building that remained lit.
 
 00:32:56.667 --> 00:32:59.633
 - The estimate is that
 there\'s a billion birds killed
 
 00:32:59.667 --> 00:33:01.533
 across the United States
 every year
 
 00:33:01.567 --> 00:33:03.733
 by collisions into buildings.
 
 00:33:09.667 --> 00:33:11.833
 [handle clanking]
 
 00:33:14.833 --> 00:33:17.800
 - This is a drawer that has
 a sample of the birds
 
 00:33:17.833 --> 00:33:20.467
 that we found at just
 one building in Chicago
 
 00:33:20.500 --> 00:33:22.300
 over the last 30 years.
 
 00:33:22.333 --> 00:33:25.300
 This has a small portion
 of the 150 species
 
 00:33:25.333 --> 00:33:29.633
 and a very even smaller portion
 of the over 30,000 specimens
 
 00:33:29.667 --> 00:33:32.200
 that we\'ve picked up
 at this one place.
 
 00:33:32.233 --> 00:33:34.700
 This is a scarlet tanager.
 
 00:33:34.733 --> 00:33:36.533
 This is the male
 in breeding plumage.
 
 00:33:36.567 --> 00:33:39.200
 This is the much less dramatic
 female.
 
 00:33:39.233 --> 00:33:41.200
 This is a very interesting bird
 
 00:33:41.233 --> 00:33:43.200
 in that it migrates
 from this region
 
 00:33:43.233 --> 00:33:45.200
 all the way to Peru
 for the winter
 
 00:33:45.233 --> 00:33:47.700
 and then back again.
 
 00:33:47.733 --> 00:33:49.700
 And it\'s one of the birds
 that it always
 
 00:33:49.733 --> 00:33:52.367
 especially striking
 when you find a dead one,
 
 00:33:52.400 --> 00:33:54.367
 realizing that it had made
 that journey,
 
 00:33:54.400 --> 00:33:56.700
 and then it ends against
 a glass window
 
 00:33:56.733 --> 00:34:00.233
 in a city in the Midwest.
 
 00:34:26.367 --> 00:34:32.367
 [solemn instrumental music]
 
 00:34:43.133 --> 00:34:44.433
 - When I was young,
 
 00:34:44.467 --> 00:34:47.267
 we\'d catch fireflies
 behind the barn in Maine
 
 00:34:47.300 --> 00:34:50.133
 just by running through
 the field with a jar.
 
 00:34:52.167 --> 00:34:54.467
 But fireflies
 like many other species
 
 00:34:54.500 --> 00:34:58.133
 that rely on darkness
 to mate, hunt, or hide
 
 00:34:58.167 --> 00:35:02.233
 are in decline because
 of changes to their habitat.
 
 00:35:04.900 --> 00:35:07.500
 - When we add light
 to the environment,
 
 00:35:07.533 --> 00:35:10.833
 that has the potential
 to disrupt habitat,
 
 00:35:10.867 --> 00:35:15.100
 just like running a bulldozer
 over the landscape can.
 
 00:35:21.833 --> 00:35:26.300
 Darkness is a necessary habitat
 for nocturnal animals.
 
 00:35:26.333 --> 00:35:29.467
 So what\'s the habitat
 for people?
 
 00:35:29.500 --> 00:35:35.500
 [dramatic percussive music]
 
 00:35:47.933 --> 00:35:49.567
 - Our society
 is moving more and more
 
 00:35:49.600 --> 00:35:53.067
 towards a 24-7 lifestyle
 
 00:35:53.100 --> 00:35:55.400
 where everything\'s open
 all night long.
 
 00:35:55.433 --> 00:35:57.400
 People are being asked
 to work very long hours
 
 00:35:57.433 --> 00:35:58.900
 and working all through
 the night.
 
 00:35:58.933 --> 00:36:00.300
 And we don\'t really understand
 
 00:36:00.333 --> 00:36:02.200
 what the long-term
 health consequences are.
 
 00:36:02.233 --> 00:36:04.200
 - [singing]
 Do-do, do-do-do
 
 00:36:04.233 --> 00:36:06.533
 - I go to work at 7:00
 in the evening,
 
 00:36:06.567 --> 00:36:10.000
 and I clock out
 at 7:30 in the morning.
 
 00:36:10.033 --> 00:36:11.500
 [whirring]
 
 00:36:11.533 --> 00:36:15.267
 - I get in at 7:00,
 and I get out at 6:00 a.m.
 
 00:36:17.867 --> 00:36:20.467
 - Everybody sitting around!
 Everybody line up!
 
 00:36:20.500 --> 00:36:22.700
 There\'s a lot of professions
 that are only at night.
 
 00:36:26.233 --> 00:36:30.033
 - We have evolved all life on
 the planet for 3 billion years
 
 00:36:30.067 --> 00:36:34.033
 with a reliable daily cycle
 of 12 hours
 
 00:36:34.067 --> 00:36:38.367
 of bright, broad-spectrum light
 and 12 hours of dark.
 
 00:36:38.400 --> 00:36:40.533
 And it\'s only been
 in the last 120 years
 
 00:36:40.567 --> 00:36:42.533
 where the masses of people now
 
 00:36:42.567 --> 00:36:45.700
 have had their dark period
 dramatically eroded
 
 00:36:45.733 --> 00:36:48.533
 by the use of electric lighting.
 
 00:36:51.767 --> 00:36:57.767
 [gentle acoustic strumming]
 
 00:37:13.967 --> 00:37:16.100
 - Ow!
 
 00:37:16.133 --> 00:37:18.933
 Not nice to slam
 into the breast cancer patient
 
 00:37:18.967 --> 00:37:21.433
 on the cancer side specifically.
 
 00:37:21.467 --> 00:37:23.833
 Anyhow...
 
 00:37:23.867 --> 00:37:26.700
 That\'s the sore side
 he just hit.
 
 00:37:26.733 --> 00:37:28.900
 We\'re on our way to
 
 00:37:28.933 --> 00:37:33.400
 I believe it is number 6
 of 30 radiation treatments.
 
 00:37:33.433 --> 00:37:37.400
 Everybody with breast cancer
 
 00:37:37.433 --> 00:37:42.733
 thinks about what can they do
 to reduce a recurrence.
 
 00:37:42.767 --> 00:37:46.067
 But most people I know
 don\'t spend an awful lot of time
 
 00:37:46.100 --> 00:37:48.900
 thinking about
 what got them there.
 
 00:37:48.933 --> 00:37:50.933
 It\'s just hard to know.
 
 00:37:53.800 --> 00:37:57.033
 - Well, sadly and remarkably,
 breast cancer
 
 00:37:57.067 --> 00:38:00.767
 is the number one cancer killer
 of women in the world.
 
 00:38:00.800 --> 00:38:02.267
 Breast cancer risk
 
 00:38:02.300 --> 00:38:06.267
 has been going up 1% to 2%
 per year relentlessly
 
 00:38:06.300 --> 00:38:08.700
 and for reasons
 that we really don\'t understand.
 
 00:38:12.667 --> 00:38:14.467
 Worldwide, risk of breast cancer
 
 00:38:14.500 --> 00:38:16.467
 has been going up everywhere
 
 00:38:16.500 --> 00:38:18.467
 and particularly
 in those countries
 
 00:38:18.500 --> 00:38:22.000
 that are rapidly
 industrializing now.
 
 00:38:24.533 --> 00:38:28.500
 We thought it had to be
 something to do with diet,
 
 00:38:28.533 --> 00:38:30.167
 changes in the diet
 
 00:38:30.200 --> 00:38:33.367
 to the high-fat, processed-food
 Western diet.
 
 00:38:35.067 --> 00:38:39.933
 The real good studies of diet
 began to hit, be reported,
 
 00:38:39.967 --> 00:38:43.100
 in the mid-1980s,
 and they were dead negative.
 
 00:38:43.133 --> 00:38:44.933
 There was no relationship
 
 00:38:44.967 --> 00:38:48.100
 of fat in the diet, for example,
 and risk.
 
 00:38:48.133 --> 00:38:50.633
 We were all very disappointed
 by this.
 
 00:38:50.667 --> 00:38:52.300
 If it\'s not diet, what is it?
 
 00:38:54.667 --> 00:38:56.633
 What is a hallmark
 of industrialization?
 
 00:38:56.667 --> 00:38:59.300
 What else changes
 as societies industrialize?
 
 00:38:59.333 --> 00:39:02.700
 And I was in my apartment
 in the middle of the night.
 
 00:39:02.733 --> 00:39:04.533
 Woke up as I usually do,
 
 00:39:04.567 --> 00:39:06.200
 and there was a streetlight
 shining in,
 
 00:39:06.233 --> 00:39:08.533
 and I realized
 it was bright enough to read,
 
 00:39:08.567 --> 00:39:10.533
 and at that moment, I wondered,
 
 00:39:10.567 --> 00:39:13.367
 \"Could electric power
 and lighting at night
 
 00:39:13.400 --> 00:39:16.900
 have anything to do
 with breast cancer risk?\"
 
 00:39:18.500 --> 00:39:20.300
 - So a series of
 epidemiological studies
 
 00:39:20.333 --> 00:39:22.133
 were done by different
 researchers
 
 00:39:22.167 --> 00:39:23.967
 all over the world at the time
 
 00:39:24.000 --> 00:39:27.000
 looking at cancer rates
 in shift workers.
 
 00:39:29.333 --> 00:39:32.133
 - The epidemiologic studies
 that have been conducted
 
 00:39:32.167 --> 00:39:34.967
 have shown that women
 who do shift work
 
 00:39:35.000 --> 00:39:38.633
 are at 1 1/2 to 2 times
 the risk of breast cancer
 
 00:39:38.667 --> 00:39:41.067
 compared to women
 who do not do shift work.
 
 00:39:46.000 --> 00:39:48.167
 [brakes squealing]
 
 00:39:50.267 --> 00:39:54.900
 - That\'s a Byzantine,
 quarter of an inch wide.
 
 00:39:54.933 --> 00:39:58.567
 So, yeah, you got to
 people like it when you measure.
 
 00:39:58.600 --> 00:40:02.233
 You measure the earrings.
 
 00:40:02.267 --> 00:40:04.233
 You measure the necklace.
 
 00:40:04.267 --> 00:40:05.900
 People like it when you measure.
 
 00:40:05.933 --> 00:40:08.700
 It\'s kind of old-fashioned
 but...
 
 00:40:11.333 --> 00:40:13.133
 I used to sell things on TV.
 
 00:40:13.167 --> 00:40:14.967
 And I would work
 in the overnights,
 
 00:40:15.000 --> 00:40:19.467
 selling a lot of jewelry
 but also clothing or cosmetics.
 
 00:40:19.500 --> 00:40:22.467
 A lot of shifts would be,
 you\'d get into work at 10:00
 
 00:40:22.500 --> 00:40:25.800
 and then go on the air
 at midnight to 3:00 a.m.,
 
 00:40:25.833 --> 00:40:29.233
 or you might be on
 the air 3:00 a.m. to 6:00 a.m.
 
 00:40:32.700 --> 00:40:34.333
 I really encourage you
 to go ahead
 
 00:40:34.367 --> 00:40:35.667
 and give me a call on these.
 
 00:40:35.700 --> 00:40:37.667
 You always have your 30-day
 money back guarantee.
 
 00:40:37.700 --> 00:40:39.333
 If they\'re not as good
 as I say they are,
 
 00:40:39.367 --> 00:40:40.833
 you send them right back.
 
 00:40:40.867 --> 00:40:44.833
 But, boy, gorgeous,
 gorgeous rhodolite earrings.
 
 00:40:44.867 --> 00:40:47.133
 If you love rhodolite,
 do yourself a favor...
 
 00:40:47.167 --> 00:40:50.133
 1998.
 
 00:40:50.167 --> 00:40:51.467
 [laughs]
 
 00:40:51.500 --> 00:40:52.900
 We had fun.
 
 00:40:52.933 --> 00:40:54.400
 Look at that scarf.
 
 00:40:54.433 --> 00:40:55.533
 See?
 That\'s easy to do.
 
 00:40:55.567 --> 00:40:59.400
 All you do is
 is, you tie it like that.
 
 00:40:59.433 --> 00:41:03.000
 - The notion that light
 could be harmful
 
 00:41:03.033 --> 00:41:06.600
 flows very natural from
 the beneficial effects of light.
 
 00:41:06.633 --> 00:41:09.767
 Anything that can heal
 the human potentially,
 
 00:41:09.800 --> 00:41:12.333
 if used inappropriately,
 can harm.
 
 00:41:12.367 --> 00:41:16.000
 How about we turn on
 the Earth skylight
 
 00:41:16.033 --> 00:41:18.833
 and monochromatic units,
 
 00:41:18.867 --> 00:41:21.167
 so I don\'t have to fiddle
 with them?
 
 00:41:21.200 --> 00:41:23.000
 In this facility here...
 
 00:41:23.033 --> 00:41:24.667
 - By studying how people respond
 
 00:41:24.700 --> 00:41:28.500
 to different types of light
 at different times of day,
 
 00:41:28.533 --> 00:41:30.833
 scientists are quickly
 unraveling the fact
 
 00:41:30.867 --> 00:41:33.367
 that light does more
 than help us see.
 
 00:41:36.100 --> 00:41:40.067
 - The nervous system has evolved
 a means for sending information
 
 00:41:40.100 --> 00:41:44.567
 based on time of day
 and light and darkness
 
 00:41:44.600 --> 00:41:46.733
 independent
 of the visual system.
 
 00:41:46.767 --> 00:41:50.600
 Light that comes into the eye
 stimulates a nonvisual pathway
 
 00:41:50.633 --> 00:41:52.633
 right towards the center
 of the brain.
 
 00:41:56.500 --> 00:41:58.800
 That information
 about light and darkness
 
 00:41:58.833 --> 00:42:01.533
 is converted
 into a hormonal signal,
 
 00:42:01.567 --> 00:42:03.533
 the production of melatonin,
 
 00:42:03.567 --> 00:42:04.867
 which in turn is released
 
 00:42:04.900 --> 00:42:07.167
 and circulates
 throughout the entire body.
 
 00:42:10.533 --> 00:42:13.000
 - During the daytime,
 when we\'re awake,
 
 00:42:13.033 --> 00:42:18.667
 our blood samples contain
 little or no melatonin.
 
 00:42:18.700 --> 00:42:21.000
 But at night, if it\'s dark,
 
 00:42:21.033 --> 00:42:23.533
 we produce
 abundant amounts of it.
 
 00:42:26.533 --> 00:42:29.333
 - The normal production
 of melatonin
 
 00:42:29.367 --> 00:42:32.000
 is what\'s called
 a circadian rhythm.
 
 00:42:32.033 --> 00:42:35.000
 Production of melatonin
 is high during the nighttime,
 
 00:42:35.033 --> 00:42:39.833
 low during the daytime.
 
 00:42:39.867 --> 00:42:45.167
 But we\'ve altered
 our light-dark environment.
 
 00:42:45.200 --> 00:42:46.833
 The eyes exposed
 to light at night
 
 00:42:46.867 --> 00:42:50.333
 will cause a very rapid
 and a very strong suppression
 
 00:42:50.367 --> 00:42:52.200
 of this hormone.
 
 00:42:55.200 --> 00:42:57.333
 - By exposing
 human test subjects
 
 00:42:57.367 --> 00:43:00.233
 to light in the middle
 of the night...
 
 00:43:00.267 --> 00:43:01.400
 Oh, my.
 
 00:43:01.433 --> 00:43:03.733
 Scientists can show
 how light at night
 
 00:43:03.767 --> 00:43:06.400
 causes a suppression
 of our melatonin levels,
 
 00:43:06.433 --> 00:43:08.633
 similar to what happens
 during the day.
 
 00:43:13.133 --> 00:43:15.433
 Dr. Brainard\'s lab
 began collecting
 
 00:43:15.467 --> 00:43:17.767
 three types of blood samples:
 
 00:43:17.800 --> 00:43:19.767
 blood collected
 during the daytime
 
 00:43:19.800 --> 00:43:21.933
 when melatonin levels are low,
 
 00:43:21.967 --> 00:43:24.767
 blood collected during
 the night in darkness
 
 00:43:24.800 --> 00:43:26.767
 when melatonin levels are high,
 
 00:43:26.800 --> 00:43:28.600
 and blood collected
 during the night
 
 00:43:28.633 --> 00:43:31.100
 after patients
 are exposed to light
 
 00:43:31.133 --> 00:43:34.333
 when their melatonin levels
 are low.
 
 00:43:34.367 --> 00:43:38.167
 These samples, from healthy,
 young graduate students,
 
 00:43:38.200 --> 00:43:42.500
 were then sent to another
 scientist named Dr. David Blask.
 
 00:43:42.533 --> 00:43:45.533
 [door creaking]
 
 00:43:47.533 --> 00:43:50.833
 - The shift work data suggested
 
 00:43:50.867 --> 00:43:53.500
 that there\'s something
 about shift work
 
 00:43:53.533 --> 00:43:55.400
 that may be associated
 
 00:43:55.433 --> 00:43:58.167
 with increased risk
 of breast cancer certainly
 
 00:43:58.200 --> 00:44:00.067
 and maybe other cancers as well.
 
 00:44:00.100 --> 00:44:01.733
 And there\'s really no way
 good way
 
 00:44:01.767 --> 00:44:04.567
 to test that in human beings,
 
 00:44:04.600 --> 00:44:07.467
 and so you go to animal models.
 
 00:44:07.500 --> 00:44:11.333
 So we\'re looking
 at this surface of the rat.
 
 00:44:15.133 --> 00:44:17.267
 In this region of the rat,
 
 00:44:17.300 --> 00:44:19.767
 we implant human breast cancers
 
 00:44:19.800 --> 00:44:22.100
 that have been grown
 in donor animals.
 
 00:44:24.267 --> 00:44:27.867
 So we have these three different
 kinds of blood samples,
 
 00:44:27.900 --> 00:44:31.700
 and we take each
 of these three blood samples
 
 00:44:31.733 --> 00:44:35.700
 and literally pump
 these blood samples
 
 00:44:35.733 --> 00:44:37.833
 directly through this tumor.
 
 00:44:37.867 --> 00:44:40.667
 - In the presence
 of nighttime blood
 
 00:44:40.700 --> 00:44:42.833
 rich in melatonin,
 
 00:44:42.867 --> 00:44:45.500
 tumor growth was suppressed.
 
 00:44:45.533 --> 00:44:47.000
 But in the presence of blood
 
 00:44:47.033 --> 00:44:49.333
 from patients
 exposed to light at night,
 
 00:44:49.367 --> 00:44:51.333
 with lower melatonin levels,
 
 00:44:51.367 --> 00:44:54.567
 tumor growth was rapid
 and fatal.
 
 00:44:54.600 --> 00:45:01.633
 - Tumors that may ordinarily
 be dormant and not very active
 
 00:45:01.667 --> 00:45:04.400
 because melatonin is around,
 
 00:45:04.433 --> 00:45:07.567
 if the melatonin is suppressed,
 
 00:45:07.600 --> 00:45:10.667
 these tumors then become active
 all the time.
 
 00:45:20.200 --> 00:45:22.333
 [crickets chirping]
 
 00:45:22.367 --> 00:45:25.067
 - One night a few years ago,
 
 00:45:25.100 --> 00:45:28.167
 someone broke
 into my family\'s barn in Maine
 
 00:45:28.200 --> 00:45:30.933
 and stole a bunch
 of my father\'s tools.
 
 00:45:34.367 --> 00:45:37.333
 My family responded
 by installing an enormous light
 
 00:45:37.367 --> 00:45:39.867
 on the corner of the barn.
 
 00:45:43.033 --> 00:45:45.667
 We haven\'t had any break-ins
 since then,
 
 00:45:45.700 --> 00:45:49.033
 but night has never been
 quite the same.
 
 00:46:08.033 --> 00:46:10.067
 - The early impetus,
 
 00:46:10.100 --> 00:46:13.900
 as recently
 as 300, 400 years ago,
 
 00:46:13.933 --> 00:46:19.400
 for public lighting was crime.
 
 00:46:19.433 --> 00:46:25.433
 [dramatic music]
 
 00:46:27.967 --> 00:46:31.767
 Virtually, every ancient
 civilization
 
 00:46:31.800 --> 00:46:35.133
 that has left clues of some sort
 
 00:46:35.167 --> 00:46:38.733
 stone tablets
 or works of history
 
 00:46:38.767 --> 00:46:43.733
 every civilization
 had a fear of the night.
 
 00:46:47.467 --> 00:46:53.267
 - This has been an area
 plagued by narcotics and guns
 
 00:46:53.300 --> 00:46:56.100
 in a perennial fashion.
 
 00:46:56.133 --> 00:47:00.667
 Now, you can look
 along the roadways here
 
 00:47:00.700 --> 00:47:04.000
 and see how dimly lit it is.
 
 00:47:04.033 --> 00:47:06.833
 Darker areas tend to be
 backfilled by offenders,
 
 00:47:06.867 --> 00:47:09.333
 and they like that
 because they can operate
 
 00:47:09.367 --> 00:47:11.167
 under the concealment
 of darkness.
 
 00:47:11.200 --> 00:47:12.200
 They can hide guns.
 
 00:47:12.233 --> 00:47:13.333
 They can hide drugs.
 
 00:47:13.367 --> 00:47:14.667
 They can wear dark clothing
 
 00:47:14.700 --> 00:47:18.000
 and recede into the recesses
 of the alleyways.
 
 00:47:18.033 --> 00:47:19.833
 That is dark right there.
 
 00:47:19.867 --> 00:47:23.167
 [police sirens wailing]
 
 00:47:23.200 --> 00:47:27.833
 If the area becomes
 too well-lit, oftentimes,
 
 00:47:27.867 --> 00:47:30.333
 drug dealers will shoot
 the lights out
 
 00:47:30.367 --> 00:47:32.233
 to provide their own darkness.
 
 00:47:32.267 --> 00:47:34.900
 [sirens wailing]
 
 00:47:34.933 --> 00:47:38.233
 When I was here in 1989
 and the early 1990s,
 
 00:47:38.267 --> 00:47:42.233
 this park was nothing more
 than a sandlot,
 
 00:47:42.267 --> 00:47:44.233
 and there were frequently fights
 in here.
 
 00:47:44.267 --> 00:47:46.067
 There have been a number
 of homicides
 
 00:47:46.100 --> 00:47:48.067
 and sexual assaults.
 
 00:47:48.100 --> 00:47:53.233
 History is replete with examples
 of poorly lit nighttime areas
 
 00:47:53.267 --> 00:47:56.733
 that are transformed by light.
 
 00:47:56.767 --> 00:47:58.567
 Fencing that you see here
 is all brand-new.
 
 00:47:58.600 --> 00:48:01.300
 The lighting stanchions
 are brand-new.
 
 00:48:01.333 --> 00:48:03.800
 - The neighborhood is filled
 with drugs and gangs
 
 00:48:03.833 --> 00:48:06.300
 and shootings
 and things like that.
 
 00:48:06.333 --> 00:48:07.967
 The lighting is not good at all,
 
 00:48:08.000 --> 00:48:09.600
 but the lighting here
 is wonderful.
 
 00:48:09.633 --> 00:48:10.767
 - Hmm.
 - It\'s wonderful.
 
 00:48:10.800 --> 00:48:11.933
 You can see anything.
 
 00:48:11.967 --> 00:48:13.767
 You can see everything
 that\'s going on,
 
 00:48:13.800 --> 00:48:16.300
 and it does have a lot to do
 with lighting.
 
 00:48:16.333 --> 00:48:19.933
 - Changing the lighting
 is a lot safer for the kids now,
 
 00:48:19.967 --> 00:48:21.400
 you know?
 
 00:48:21.433 --> 00:48:23.100
 It\'s not like
 it used to be before.
 
 00:48:27.667 --> 00:48:30.467
 - There is controversy
 over whether more light
 
 00:48:30.500 --> 00:48:33.133
 leads to less crime,
 
 00:48:33.167 --> 00:48:34.467
 but there is agreement
 
 00:48:34.500 --> 00:48:37.133
 that light seems to make people
 feel safer,
 
 00:48:37.167 --> 00:48:39.300
 almost like it\'s built
 into our genes
 
 00:48:39.333 --> 00:48:42.767
 to move closer to the campfire
 or to the brightest city.
 
 00:48:44.800 --> 00:48:47.933
 - Light does facilitate
 
 00:48:47.967 --> 00:48:52.033
 social interaction
 on a massive scale.
 
 00:48:54.000 --> 00:48:57.900
 - The twinkling of cities
 at night always says to me,
 
 00:48:57.933 --> 00:49:01.133
 \"Look at us as a species,
 you know.
 
 00:49:01.167 --> 00:49:02.467
 \"You\'ve seen anthills.
 
 00:49:02.500 --> 00:49:05.800
 \"You\'ve seen the nests
 of bowerbirds.
 
 00:49:05.833 --> 00:49:07.500
 This is what we do.\"
 
 00:49:09.667 --> 00:49:11.800
 - You could think of our era
 as the one in which
 
 00:49:11.833 --> 00:49:14.467
 the stars disappeared
 from the sky
 
 00:49:14.500 --> 00:49:18.467
 and reappeared
 in our city skylines,
 
 00:49:18.500 --> 00:49:20.200
 which could help explain why
 
 00:49:20.233 --> 00:49:22.700
 I began to feel
 a kind of affection
 
 00:49:22.733 --> 00:49:25.700
 for the way the city
 used light as art,
 
 00:49:25.733 --> 00:49:29.067
 as celebration, as tribute.
 
 00:49:34.067 --> 00:49:36.700
 But at this point,
 I also saw the birds
 
 00:49:36.733 --> 00:49:39.267
 flickering and lost
 in the city lights
 
 00:49:39.300 --> 00:49:42.800
 and the streetlight
 pouring in my bedroom window.
 
 00:49:44.567 --> 00:49:48.900
 Though we might love the light,
 we might also need the dark.
 
 00:49:52.100 --> 00:49:56.433
 - An important part of our work
 and my work
 
 00:49:56.467 --> 00:50:00.700
 is to explain
 and convince my clients
 
 00:50:00.733 --> 00:50:03.200
 that they don\'t need
 so much light.
 
 00:50:03.233 --> 00:50:07.533
 They need light
 where it\'s required
 
 00:50:07.567 --> 00:50:10.533
 but not in a very uniform way,
 
 00:50:10.567 --> 00:50:12.833
 not diffused all over the place.
 
 00:50:15.367 --> 00:50:18.667
 When you have a very diffuse
 light, you have great
 
 00:50:18.700 --> 00:50:20.167
 you have a lot of glare.
 
 00:50:20.200 --> 00:50:21.500
 And you look here.
 
 00:50:21.533 --> 00:50:23.333
 You have no idea that
 you have a sky behind you.
 
 00:50:23.367 --> 00:50:24.500
 You see the glare.
 
 00:50:24.533 --> 00:50:25.833
 You have no idea where you are.
 
 00:50:25.867 --> 00:50:28.500
 You could be anywhere.
 
 00:50:28.533 --> 00:50:30.500
 So it\'s still
 under construction here.
 
 00:50:30.533 --> 00:50:33.167
 It\'s not finished yet.
 
 00:50:33.200 --> 00:50:35.833
 - When Hervé Descottes
 designed the lights
 
 00:50:35.867 --> 00:50:40.000
 for New York\'s newest park,
 the High Line in Manhattan,
 
 00:50:40.033 --> 00:50:43.167
 he designed them
 with the night in mind.
 
 00:50:43.200 --> 00:50:47.000
 - You can see, the light
 is completely hidden here.
 
 00:50:47.033 --> 00:50:49.667
 It\'s underneath here.
 
 00:50:49.700 --> 00:50:52.333
 So you don\'t see
 the light source.
 
 00:50:52.367 --> 00:50:55.033
 And look at the effect.
 
 00:51:01.800 --> 00:51:04.933
 Try to imagine
 a different type of city light.
 
 00:51:04.967 --> 00:51:09.933
 How could we light our city
 in a more careful way,
 
 00:51:09.967 --> 00:51:14.767
 where you feel safe,
 where you find your direction?
 
 00:51:14.800 --> 00:51:16.600
 It\'s where you can escape
 
 00:51:16.633 --> 00:51:19.267
 and be connected
 to a darker sky.
 
 00:51:24.500 --> 00:51:28.200
 - The thing that makes me
 optimistic about light pollution
 
 00:51:28.233 --> 00:51:30.833
 is that it\'s
 a win-win situation.
 
 00:51:30.867 --> 00:51:33.533
 Reducing light pollution
 hurts virtually no one,
 
 00:51:33.567 --> 00:51:34.600
 and it saves money.
 
 00:51:36.567 --> 00:51:38.933
 - Reducing light pollution,
 it turns out,
 
 00:51:38.967 --> 00:51:40.833
 a matter of design.
 
 00:51:40.867 --> 00:51:42.367
 On many lights,
 
 00:51:42.400 --> 00:51:44.867
 the light doesn\'t go down,
 where it\'s needed.
 
 00:51:44.900 --> 00:51:47.333
 It actually goes up.
 
 00:51:47.367 --> 00:51:49.767
 As much as half
 of what we see from space
 
 00:51:49.800 --> 00:51:51.567
 is wasted light.
 
 00:51:55.133 --> 00:51:57.867
 Partly because wasted light
 costs the country
 
 00:51:57.900 --> 00:52:01.367
 an estimated $1.5 billion
 every year,
 
 00:52:01.400 --> 00:52:03.867
 engineers are designing
 full cutoff lights
 
 00:52:03.900 --> 00:52:05.733
 that direct light only downward.
 
 00:52:05.767 --> 00:52:08.767
 And many communities
 across the country,
 
 00:52:08.800 --> 00:52:11.767
 including one just up the road
 from my childhood home,
 
 00:52:11.800 --> 00:52:15.733
 are enacting new ordinances
 that restrict wasteful light.
 
 00:52:21.867 --> 00:52:24.067
 [seagulls screeching]
 
 00:52:27.733 --> 00:52:31.033
 - We\'re now a week away
 from the November 4th election,
 
 00:52:31.067 --> 00:52:32.700
 a big election for many,
 many reasons.
 
 00:52:32.733 --> 00:52:34.867
 Here on Mount Desert Island,
 
 00:52:34.900 --> 00:52:37.867
 a lighting ordinance
 is up for ratification
 
 00:52:37.900 --> 00:52:40.033
 by the town of Bar Harbor,
 
 00:52:40.067 --> 00:52:42.733
 and we\'re hopeful
 that it will pass.
 
 00:52:45.967 --> 00:52:49.200
 - This is considered
 one of the last remaining
 
 00:52:49.233 --> 00:52:52.533
 pristine dark night skies
 on the East Coast.
 
 00:52:52.567 --> 00:52:55.533
 There definitely is a sense
 of urgency in this area.
 
 00:52:55.567 --> 00:52:58.367
 Folks are seeing
 the big-box stores arrive
 
 00:52:58.400 --> 00:53:02.467
 along with big lights
 in the parking lots and so on.
 
 00:53:12.133 --> 00:53:15.100
 - I went out
 to different neighborhoods.
 
 00:53:15.133 --> 00:53:17.100
 I\'d say, \"Okay,
 why do you live here?
 
 00:53:17.133 --> 00:53:20.600
 And what\'s so great about living
 in this part of Bar Harbor?\"
 
 00:53:20.633 --> 00:53:23.933
 And they all said,
 \"We love our night sky.
 
 00:53:23.967 --> 00:53:26.967
 We love going out at night
 and looking up.\"
 
 00:53:29.000 --> 00:53:30.467
 It really boils down to,
 
 00:53:30.500 --> 00:53:33.600
 you know, only put light
 where you need it.
 
 00:53:36.900 --> 00:53:39.833
 - Bar Harbor passed
 its lighting ordinance,
 
 00:53:39.867 --> 00:53:44.133
 and back at my family\'s house,
 we followed suit.
 
 00:53:44.167 --> 00:53:46.400
 [wrench clicking]
 
 00:53:48.633 --> 00:53:50.167
 Our new light
 would save us money
 
 00:53:50.200 --> 00:53:51.667
 on the electricity bill,
 
 00:53:51.700 --> 00:53:55.533
 but it was harder to quantify
 all that we gained
 
 00:53:55.567 --> 00:53:57.233
 as the stars came back...
 
 00:54:05.900 --> 00:54:07.633
 Perhaps the night sky
 
 00:54:07.667 --> 00:54:10.200
 and whatever stars
 we are lucky enough to see
 
 00:54:10.233 --> 00:54:13.167
 help us reorient,
 
 00:54:13.200 --> 00:54:15.367
 help restore something in us
 
 00:54:15.400 --> 00:54:17.767
 that is lost under city lights.
 
 00:54:28.633 --> 00:54:31.267
 - We have lived under the stars
 
 00:54:31.300 --> 00:54:35.933
 for the vast majority
 of our experience.
 
 00:54:35.967 --> 00:54:38.100
 Go back the last million years.
 
 00:54:38.133 --> 00:54:42.200
 How much of that time
 have we been inside
 
 00:54:42.233 --> 00:54:44.867
 in air-conditioned,
 heated,
 
 00:54:44.900 --> 00:54:48.000
 hermetically sealed
 little boxes?
 
 00:54:48.033 --> 00:54:49.833
 It\'s very recent.
 
 00:54:52.367 --> 00:54:56.000
 So naturally,
 there\'s a kind of dislocation.
 
 00:54:56.033 --> 00:54:59.500
 You know, it seems to be
 that there\'s this desire
 
 00:54:59.533 --> 00:55:03.067
 to know what the universe
 is like.
 
 00:55:03.100 --> 00:55:06.400
 You know, this is the mystery
 that we were all born into.
 
 00:55:14.067 --> 00:55:17.067
 - You could live your life
 at home, never looking up.
 
 00:55:17.100 --> 00:55:18.433
 You know what\'ll happen?
 
 00:55:18.467 --> 00:55:20.500
 You\'ll start thinking
 of your own environment
 
 00:55:20.533 --> 00:55:22.033
 as all there is.
 
 00:55:22.067 --> 00:55:25.533
 And if that\'s how you think
 about where you are,
 
 00:55:25.567 --> 00:55:31.867
 then it rises to an artificial
 level of importance to you.
 
 00:55:31.900 --> 00:55:33.533
 Whereas when you look
 at the night sky,
 
 00:55:33.567 --> 00:55:37.533
 and you realize how small we are
 within the cosmos,
 
 00:55:37.567 --> 00:55:42.300
 it\'s kind of
 a resetting of your ego.
 
 00:55:49.800 --> 00:55:53.267
 - The reason to be able
 to see the night sky
 
 00:55:53.300 --> 00:55:54.667
 is really in the end,
 
 00:55:54.700 --> 00:55:59.467
 I think it\'s more spiritual
 than practical.
 
 00:55:59.500 --> 00:56:03.033
 - Imagining how far away
 the stars are
 
 00:56:03.067 --> 00:56:05.033
 and grasping that.
 
 00:56:05.067 --> 00:56:07.200
 And what is coming of age
 
 00:56:07.233 --> 00:56:10.900
 but realizing that you\'re not
 the center of the universe?
