Illuminating the Effects of Light Pollution
www.nytimes.com/interactive/20...
"In many bustling cities and towns, bright lights from towering high-rise buildings, houses and street lamps obscure views of the cosmos and contribute to an environmental problem called 'light pollution.'"
Light Pollution Taking Toll on Wildlife, Eco-Groups Say
news.nationalgeographic.com/ne...
"Light pollution also endangers sea turtles. Beaches in sections of Florida's highly developed coastline are nesting ground for rare loggerhead, leatherback and green turtles. Bright lights nearby discourage females from coming ashore to nest."
Missing the Dark: Health Effects of Light Pollution
www.ncbi.nlm.nih.gov/pmc/arti...
"When does nuisance light become a health hazard? Richard Stevens, a professor and cancer epidemiologist at the University of Connecticut Health Center in Farmington, Connecticut, says light photons must hit the retina for biologic effects to occur. 'However, in an environment where there is much artificial light at night-such as Manhattan or Las Vegas-there is much more opportunity for exposure of the retina to photons that might disrupt circadian rhythm,' he says."

Honestly, at this point, what DOESN'T give us cancer?
Cancer
lol- I think cancer gives u cancer, but if the cancer has cancer then I guess not....?
dying
Your mom
Classic
I live the Australian outback, the milky way is try a beautiful sight. I feel sorry for big city folk
Jonatan Borowicz that's a shame then
No one cares about stars though in the city
The Long Islander speak for yourself i live in a big city and when i look into the sky i feel sad that i cant see the milky way bcz of light pollution
Lol
i envy you
Damn....we cant stop fucking this planet can we?
Marcelo Souza ok turn off your lights and never use them because it's bad for the world. Unless you practice what you preach, don't complain.
nope we can't because one person thinks "why should i do it 1 person won't make a diffrence" but with those thoughts nobody is going to start helping the environment
oh trust me the planet is fine... the only thing we really are fucking is ourselves
+Hunter Rodrigez I agree but you don't need to say we because only higher ups can take dicisions for all of us
***** whats there to explain ? this planet has survived things faaar worse than us puny little humans
even if we fired every single nuke we have at once the earth would be fine, i mean yeah it would probably take a million years or so to fully recover from us... but thats not exactly a long time for the earth considering that its 4.5 billion years old and will be a venus like wasteland one day anyway no matter what we do
Light pollution can affect your health, it makes me feel... light headed.
Master Therion Badum tss...
( ͡° ͜ʖ ͡°)
Master Therion *Lucky, for you light pollution gives me the runs*
GET OUT

Ok but can we talk about businesses? I never understood "security" lights when the store/business is closed. You're just wasting energy. Put in those motion sensor lights; boom, multiple problems solved. Uses less energy, doesn't pollute, and if someone does try to break it it'll be a helluva lot more noticeable when all of a sudden the lights turn on.
What to do if you live in a light polution area? We can not see this in citties with naked eye. There is too many light polution and we do not have night time or dark stime without light polution. The only option is to travel in a place without light polution. This is our modern probelm. We did not have this problem 200 years ago.
I had no idea you were even supposed to be able to see the Milky Way at night
Emstarx I believe you can see 1 or 2 of our spiralling arms.
You can't see any of the arms because you are looking at it on a plane while you are inside of it. I guess technically you can see all the arms, you just can't distinguish them
you can see 2 other galaxies :O
Go camping, or to a some what desolate beach. I live in NJ and can't see the milky way unless I do either of those 2 things .... Seeing the Milky Way is quite possibly my favorite thing to do, I look forward to it all year until I go on vaca and sometimes don't even go to bed staring at the sky all night when I'm there.
fafillionaire i live there too, but no matter where ive gone i cant see more than 20 stars
great to have a doctor talk on Dnews yet again. She was amazing, good speaker and very educated (y)
...and beautiful.
You're beautiful also, Raquel.
Having a Doctor does not make someone smart
Zutaca Really? You never stepped on a Lego in the dark? And surely I shouldn't have to mention The Boogeyman!!!
Raquel Fernandez *Sup baby ;)*
Wow. Thank you for lighting up this issue.
No One stop what?
No One ohh I didn't even realise that was a pun
No One
I say we kill it
Yeah I know, it was very enlightening.
jeez, lighten up will you.
This is why nighttime is more lit than day time
yeh, both kinds of lit madude
Fabulous Miku nighttime is lit. 😏
Well then… hello darkness my old friend
when i was i kid my room was always illuminated by like 15 street lamps and i always had trouble sleeping... now i sleep in complete and utter darkness, and iam talking about the "you cant tell if your eyes are open or closed" kind of darkness
dats too much for meh. that kind of darkness makes me want to poop a sun
Hunter Rodrigez
damn I used to sleep at that kind of darkness when I was a kid. Now I miss it :') How did you do it?
Donut how did I get my room so dark? 3 layers of curtains and duct tape over everything that Emmitt light when I don't want it to like standby LEDs on electronics and stuff
I'm guess you sleep better now. Do you do anything for noise?
Hiro Fox i listen to music to fall asleep and while i sleep... different kinds of music can lead to some pretty interesting dreams
and when i have trouble falling asleep i listen to some hour long recordings of rain i got from youtube
"Dad can you keep the lights on?"
"Do you want this baby turtle to die?"
"No dad, put the hammer down!"
Can I do anything without having to feel horrible about it?
ikr...it's like sometimes they forget that we're HUMAN and LIVING ORGANISMS TOO! Its like why is evryone else adapting and we have to stop doing certain things.
TheFluttershyFan Yes just ignore it all 🙄
Daniel well we can learn to adapt to not needing light to see at night, which will take lots of years of evolution
TheFluttershyFan I drink coffee made from organic dolphin anus harvested by starving children in Africa and have never felt a hint of guilt. You can do the same if you set your mind to it!
If you do something about it you won't feel horrible
What if you're afraid of the Boogeyman and you leave light on every night.
Lorenzo well then you're a child
Lorenzo I feel you
Ball is life the Boogeyman doesn't care about age ;)
You're doin it wrong m8. He can't see you without any light!
He can't see you if you can't see him!
Sleep with a really big stick next to your bed and if you hear something, you can sit on your bed menacing the darkness with your stick until you feel better.
i dont live in a city and ive never seen a milky way but it gets very dark at night but anyways once i watched the video i turned off my room light
LOL
Fascinating.
Betty Brown I only see the big dipper
Look at the bright side...
Look at the dark side...
siths, we hate em, but ya gotta love em
talha tariq Lol XD Hahaha
The bright side may no longer remain bright after watching this video.
Well that's what we are doing :)
We should turn off the lights at streets like North Korea did.
no they just can't afford so much electricity
Leo N that's just redirecting the power to the electric fences at night to keep people in.
lasarith2 And also in some buildings and the streets
you will be surprised how bright it is at night when you don;t have artificial light but a clear sky and btw if it;s a clear full moon again it;s super bright outside, yeah it;s a bummer when it;s cloudy or you have shading structures but we can make low power lights to mimic that. so solutions exist but ppl are retards and bring politics and propaganda into this like you do.
Romania de azi that was supposed to be a joke you numb skulls
*Theses ads are polluting my youtube. It's becoming a serious problem. If we don't act fast, we no longer be able to watch videos!*
Wtf I searched this up
Ooh, I like this new host. Clear speaking, minimal gesticulation. AND ALMOST NO VOCAL FRY. It's nice to hear.
It's a great thing that *Rock and Roll Ain't Noise Pollution*. I don't know how I'd live without it. ;)
RJTheHero ha, awesome comment
Awesome song. I'm going to have to crack that one up and annoy my neighbors.
Let there be Rock!
Light pollution started when man discovered fire. It's been "HELL" since.
Thanks for shedding some light on this topic.
My doctor prescribed me for a chest X-ray. I got a diagnosis of Asthma. The reason was because I had my windows open and I live near a freeway in Los Angeles. All the fumes coming from the cars on the freeway effected me. It must be worse in China due to their huge population and the many cars on the roads.
Christian Gonzales How is that relevant to the video?
PixelKnighty Light pollution is more dangerous than you think. At the end of the video they asked the viewers to share their experience with light pollution, so I shared mine.
Did you even watch the video? That's not light pollution, that's particulate pollution.
Thats carbon pollution, not light pollution.
I did watch the video and my bad about mixing up the type of pollution. Still doesn't dismiss the fact that pollution is pretty bad around the world.
I've never seen the milky way :(
I've stayed out till 3 am doing a star-trail photo in the mountains though. I picked a bad night, it was a half-moon. It was my first time doing astro photography or whatever. I was not happy with my picture but I had fun so it was worth it! :)
Reptarsaurus takes a while watch more videos on it here , when I took a picture of the sky all that showed up was the moon even though their was 1000s of stars out that night, the sensor in the camera gets overwhelmed by the light of the moon compared to the stars around it, but you'll get it eventually 🙂
Come to my place. I will show you the milky way. :'D
You don't see the milky way with the same clarity everywhere.
In Europe, for example, you won't see it very well. Almost to the point, where you will not notice it, unless you know where it is. Same goes for the middle part of the US.
In more northern regions like Scandinavia, Canada, North pole... you should be able to see the milky way pretty good. North pole is perfect for that, of course.
The visibility scale I wrote down for northern regions is the same for southern regions.
Of course if you use a telescope from an observatory, you will be able to see it from everywhere. This is my personal experience, by the way.
As for pictures, you can take good pictures even at half moon. You just have to set exposure time/shutter speed for at least 20 seconds to get a good shot. I remember doing a project for school and the guys at the observatory where using 1-3 minutes of exposure time for the pictures. Also, a camera with a lot of MP doesn't always mean good for astro photography.
What you could try is: take the photos you took and layer them on top of each other with a program, like...5 or 6 layers. That is if you can see anything even slightly dim on those photos. That's a normal practice with this type of photography. Maybe you're lucky and the photos will turn out to be more vivid.
AwesomeWinter Thanks for the tips! I don't think I will be able to travel to the North Pole anytime soon haha, especially at this time of year :P.
I just looked back at my pictures and I might just be over-critical. I mean, they're boring to look at composition wise but you can clearly see all the stars. Red, blue, white, and a big purple one. Although that particular picture was at 10 sec. The startrail photos were at 30 sec and there had to be at least 50 layers
Next time I go to the mountains I might stay up late and take more photos and try the layering trick you said to have them be more vivid.
Reptarsaurus Well, given what you said, your photos are actually pretty good! :D
I mean, if you can distinguish the stars on a photograph, that's already very well done!
Yea, sure, experiment with it. You can even take photos in town, if you want. I did it once, didn't turn out to be that bad. Anyway, I wish you best of luck with the photographs, have fun with it!
Oh and by the way, don't worry about the north pole. There aren't any penguins there and Santa is hiding like a pro. South pole is so much better in that regard. I mean....Penguins! What can possibly beat penguins.
This was was satirically exciting to watch. The humor of sarcasm is so important to exemplify the important underlying message. Thank you for this. My lights stay off.
Great. Keep it up bringing attention to such ignored but important issues.
I remember standing outside as a kid at night, and looking at the milky way. I still live in the same area, and I haven't seen the milky way that clearly in years.
Jesus every place humans inhabit alters or destroys the habitats of other species, and light pollution is an extremely small part of it. And no one in their damn right mind leaves the lights on in the house when they go to sleep. It's the city lights that are really necessary for not just the regular people working night shifts, but also truck drivers without whom we can't have any shit in our lives. If the lights outside are too bright, get a curtain. Simple.
Stop implying suggestions to not use night lights. The good far outweighs the bad.
Awesome new host. Cool you guys have ability to get experienced people on your show. Very clear speaker, good energy, maybe toss some more dorkyness in and you've hit gold.
Thank you for bringing light to this problem!
I hope power in my city will turn off something in a cloudless night so I can see the universe
Rick van der Grient I hope my neighborhood turns off their street lights because they are way too bright
U see sky everyday & not the milky way dude...
69 Solo you're right, I will change it
I just hope my neighbours stop putting up strobe lights for Christmas.
You will freeze
2:31 she said LIT.
I can see the stars and constellations on most clear nights, which isn’t many, since I live in UK(clouds)
I live in Northern Ireland, near a 10k population city
When you live in a port city, at a major choke point for shipping lanes, where 2 thirds of all ships pass through, the memory of the stars in the night sky will easily fade away and anything related to that can only be seen on the internet. The port works all day, in the mornings everyone works for long hours, and sleeps only for a little time. This is my life, and honestly, it is not hard to wonder what's outside.
Hello, I was wondering if my group can use some of the clips (0:52, 2:16) in this video for a environmental movie that we are working on to submit on Planet in Focus festival? Thank you for your time.
Even living outside of the one of the most northern major cities (Edmonton) in north america it is rare for me to see the northern lights even in the dead of winter when its dark from 5-6pm and 8-9am. I'm only 20 but remember seeing the Aurora Borealis much more often and significantly more vividly. It saddens me, its so beautiful, it often makes me wish I lived further from major populations so I could enjoy the nature beauty more.
I don't use night lights, not particularly bothered by the dark and it's quite amusing to use natural night vision.
More importantly what can be done about street lights and such? We're well past the point of being able to have them turn on by proximity or something in the dead of night so we can have them off most of the time, or making them less intense and such I imagine.
Thanks for shedding light on the effect of being exposed to light pollution! Next time when I want to fall asleep quickly, turn off the night light will be my choice.
I live way out in the sticks where it gets dark. Love it...
I’m planning to move to a national park in my province to be on a farm. The only thing you can do there is own a couple of horses and just live there because all of the trees belong to the animals. Well, so does your house since the foxes don’t care if they are near a house or not.
I have always thought and wanted no artificial light as I would like a true view of the night but that doesn't mean we can't have torches :) but I would love to see a future where street lighting is a thing of the past.
I actually can see the milky way where I live :D there's still some lights which I hate tbh.
reeeeeeeeeeeeeeeeeeeeallllllllllly that's awesome.
I wish I could ;(
I wish i could see it everyday. Tired of this city life with all the drama and bullshit with people nowadays.
Golden Trout it's truly amazing but not romantic since goats and cows are always calling out every so often.
Dulce G LOL! Gladly have more nature in my life.
Lucky
Great. thanks for shining LIGHT on this issue😀
we as humans need to step in the way of all types of pollution
What you can see the Milkyway from Earth? 😅 I feel dumb now
Javier Negron Lopez just 1 or 2 of our spiral arms
Javier Negron Lopez It's beautiful, trust me.
Laura Gadille I live in a country with number 1 ranked light polluted. I don't see a single star in the sky. Only the moon. I wish to see it one day though. Any idea where I could go to? And no, there's no forest in my country. All is nature reserves and they're near cities
Donut i live in Puerto Rico so we are having the same problem now hehe
I live in a small city where there is a lot of light too. Our local fair has spots where I park my car and watch the sky's. There is no lights. Where ever there is a spot with no lights.
You're right. I live in Toronto and I also haven't seen the stars of our galaxy due to light pollution
i live in a small vilage and still cant see the milkyway and barely any stars. nearest city is about 40km away
Amazing content! I had no idea about all these bad things :(
Palm Springs doesn't have street lights so that we can see the stars at night! The major intersections have street lights and signals but in the neighborhoods there are no street lights. Stars so close it seems you can reach out and grab one!
Wow! I never have thought of this. Thank you
Finally. I researched light pollution 3 years ago for a science competition. I got second place.
It's been over 16 years since I last saw the stars in a decent number, however I've never seen the Milky Way. I didn't even know it was possible to see it.
Desperate for HELP with Light Polution in Joplin MO! We live just outside of town backed up to nothing but fields, trees, deer, turkys, and a variety of wildlife critters...New neighbours put up 50ft high STADIUM LIGHTS to light up not only the fields & woods, but Everyone's yards reaching 5 houses away. Our entire eco friendly way of life has been ruined, as it is now daytime 24/7 intruding into all our windows. The wildlife has disappeared, deer and turkey no longer even visit the feeders and salt licks we have on our fence line....I've posted several before and after pic on Facebook & am in desperate need of help. Wish I could add pics here.
We have laws restricting light pollution in Hawaii because of lens flair on the telescopes up on the mountain. It's great to not have blinding white light at night. We only use LED and low pressure sodium. This is so that they can adjust for that specific bandwidth of light on the telescopes.
I went to Mexico a some time ago and I noticed there were like 30 stars then the usual 10 I see in California. This amazed me to see more stars but I have yet to see the Milky Way
1: I'm not heartless, I just can't make people turn off their lights.
2: I have curtains
3: My home is powered by 4,000 windmills, so i'm sure it's ok to leave the lights on here
BTW, search "windmills palm springs" in google images, you will see the 4000 windmills
finaly the very beutiful and stunning doctor Sapna is back !!!!!!!!!!!!!!!!!!!
Thanks for this, I can look at this kind of pollution in a new light
Dayum!This sparked a "Light" in my brain!
"I could fall into a pleasant sleep listening to her voice" **sees her name is 'Sapna'** ...whoa
In WWII German submarines used to take advantage of the glow coming from the east coast and use it to spot targets.
I Work overnights and do not see much day light these days. Is this effecting my health??
You're really highLIGHTING this issue
What I don't understand is why office buildings leave their lights on all night. There's nobody in there, so why are they wasting energy and money?
Also, why do cities blast the light from street lights onto people property? Why do the street lights illuminate people's yards? Can't they make the light more focused?
i was on the line of depressed n happy today...this nudged me over to depressed, the truth sux, but keep up the great show! but yeah, earth...what a mess.
Go to Mars and make it your home planet. The Earth is starting to look like a lost cause.
Thx for enlightening me!
Think of how much we'd save on the cost of electricity and frequently replacing light bulbs too.
I can't watch this video. It just buffers. But it's ONLY this video.
whyyyyy
Clear your TH-cam Cache
How do you do that on mobile?
Oh well, doesn't matter. It started working again.
CCleaner.
I watched an entire clutch of baby turtles crawl along the dike, trying desperately to get to the city... I took armfuls of them to the ocean and gently tossed them in, but when the waves brought them back to shore, they crawled back again away from the ocean... There was nothing I could do... :'(
physical atmospheric pollution reflects light, making light pollution worse, just another way your car (and pretty much everything else you buy becasue factories, mining, coal power, etc) is killing you
Mirrors also reflect light so stop looking at yourself
frogs and toads cant ribbit when they're too lit. damn :(
I have never seen the Milky Way at night. I have only ever seen it on TV. I am also an Insomniac, I don't sleep, at all. I haven't properly slept since I was 15, I'm about 27 now.
I live near LA and I can only see a handful of stars..
such an enlightening video...
I like the tan or dark containers to put my weed in because I think the light messes with the THC
Well Done Dr.Sapna...Keep it up
i would like to have a butifol sky instad of a arteficial one ....
It's sad to think some people will never see the Milky Way. It's a glorious sight.
What’s the city in the thumbnail.
I recently moved to New York from Georgetown Guyana. about 90% of the stars aren't visible.
ok you got me with those baby turtles, i'm causing a total black out on my town...
I have nyctofobia... I feel somehow bad for leaving my lil light companion when I go to sleep... sleep with light on like 7 years old kid... geez
funny, iam the exact opposite... i cant sleep comfortably unless its so dark you cant tell if your eyes are open or closed
***** I tried that once and from that day I will never underestimate word "fobia". It felt like my brain is going to KO me for scaring his god damned neurons :D
I dont know why, but I really enjoyed that you called it a "lil light companion"
up Light pollution affects my sleep and I am advocating in my city province and country to try and solve this problem. I wish governments would listen.
You can live comfortably without being messy. Live with efficiency rather than convenience. Embrace the darkness... don't fear it.
Fear is a very useful tool.
convenience is efficiency
good thing where i live at it's mainly mountains and very little night ilumination (mostly 'cause the street lights are broken :y vandalism)
This is in the big cities, not in my small rural hometown.
Holy wow! She is gorgeous!! :D Love Dnews, love this awesome lady!
That mentors fresh now mints ad is always buffering. Ugh
A washer necklace... What
Didn't New York experience the power outage in 2003? That would have been a better example to use, I think.
Can we turn the lights down now?
oh my goodness
Thanx for the added info...would have liked more stat info (just me) though.I've seen the milky way in the Karoo (middle of fuck-all and nowhere in south africa), wish i could see it every night in the city
It's more interesting how most of the population have zero clue on how this is effecting their health.
Definitely one of the hottest women working for DNews
It's probably because she's dressed in layers. If she's too hot, she can take off the top layer. Dressing layers is smart.
Johnny Kronaz You make a valid point good sir
I don't think i ever got to see the milky way. Just some stars. Its sad.
New host? Very well spoken.
i cant make timelapses of stars in cities it takes me hours to get to a place where i could do that, i live in Stockholm Sweden.
"To see the most starry and magnificent sky you need to go to the darkest places"
Didn't know it was serious. That Dr. is good looking
I'm in India so no problem at all because they cut power many times in a month ,so many villages side people are actually guided by the moon at night so less light pollution
