- Landscape astrophotographer Alyn Wallace ( / alynwallace ) discusses the devastating impact of light pollution, not just on the night sky but on nature as well. As the human population explodes and towns and cities grow, light pollution is growing at an alarming rate and is largely going unchecked. Not only is the luminous fog drowning out the stars and our view to the rest of the universe, but it also causes disruptions in circadian rhythms and the balance of ecosystems.
Alyn Wallace is a landscape and timelapse astrophotographer based near the Brecon Beacons National Park in South Wales. He was featured on the BBC Two “Moonshot” documentary to mark the anniversary of the moon landings, where he set out to take his ultimate image of the moon, and celebrate Wales’s Dark Sky Reserves. Alyn's work has been recognised by NASA, National Geographic, the BBC and The Times, among others. Alyn shares his knowledge through Astrovlogs on his CZcams channel and hosting astophotography workshops in Wales and Europe. His work can be found at: alynwallacephotography.com/. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
Rest in Peace Alyn! You've left such a positive mark on the community and everyone is so appreciative of your hard work.
Watching this again after hearing about his passing. Truly inspirational. Thank you
"Turn the bloody lights off" haha. Well spoken, Alyn. Lovely presentation.
Such an important topic that we should take a lot more seriously. Thank you Alyn for the great talk!
RIP Alyn Wallace you’ll be missed
Alyn once made a video where he talked about some of his struggles in life and how he found his own personal peace through photography. Having gone through similar things, I found great inspiration in his words which led to me finding my own solace in photography. He genuinely touched my life and will be missed by many.
Great talk from a master in his field. This should make us all sit up a think!!
He is a master of fake sh!t..
@@ZackWolfMusic what was fake?
@@Keenan716 His enhanced images of the milky way using software to make the milky way more brighter with wild colors when it is never not. This channel also has other sh!t like fake images of Nebulas. You believe in this phony baloney sh!t all you like! I not here to change you.
@@ZackWolfMusic It's not fake images you jackass! LMFAO i take images just like these tf? Actually leave the city and see it for yourself you clown!
@@Keenan716 Show me your damn images if it's not fake sh!t. I'm waiting I'm waiting I'm waiting I'm waiting opps you don't have sh!t to show and if you did it would be sh!t quality... GTFOH you clown..
Rest in peace alyn😢
Amazing job. Time to shed some more light ironically, to this subject.
It disgusts me when i see big cities, love it when you are out in total darkness and just the stars
Great talk Alyn! I was born in Wales, but never realised how beautiful the night sky could be until I visited Switzerland.
Only just found this - what a superb presentation and full of facts that I never realised. Im inspired to share this and to forward to local authorities here in Oxfordshire who are right now, installing these LED lamp posts and yes, one right outside my bedroom window - explains a lot! Thank you Alyn.
How has this only had just over 3k views!! It's amazing
i follow his youtube channel..such a nice guy...
love his content on astro photography
Great presentation, very interesting to see.
Great job.... I'm very lucky where I live.... North Norfolk. Great presentation.
Light pollution is also major issue. We must have to Raise voice against it & try to fix this issue...
Beautiful. I live in guatemala and we have many areas that are amazing to view the milkyway!
Light - and noise - pollution are extremely destructive, more so than anything else, in my experience.
I find the clinical blue rich LEDS very uninspiring, soul sapping, overly intrusive and artificial looking light. They might be considered safe but they are not very healthy. Nature is not an office block. thanks for the talk dude.
Thank you for this very informative talk. I never realized the impact of LED light in wildlife.
Saddened to hear of the passing of Alyn. Taken from us way too soon!
The irony is that the blue LED is a Nobel Prize winning invention.
Yes. Another award given by mad scientists to mad scientists. I expect a nomination soon for the inventors of Covid19.
Also, when it's cloudy the artificial light reflects off of the clouds and makes everything even brighter. You literally see the beams of reflected light from the clouds shining through the gaps in the curtains. Awful!
Very informative presentation. Helped me a lot with my research paper. Grateful!
i am an astrophotographer too ... hate light pollution but this was too big and deep dive into disadvantages of light pollution love alyn
So true wen I lived in the city I never saw the stars, when I returned home to the country I was amazed by the bright stars & the milkyway breathtaking
Alyn, I used to live in the middle of Salisbury Plain and we had some very good dark skies. On a clear night you could easily see the Milky Way. The only problem, was like most places in UK whenever there was a major astronomical event, we were clouded out or frozen out, especially during the Winter months. Now I'm retired, I have solved even that problem, no light polution, no cloudy skies, no freezing cold nights - I now live in La Palma in the Canary Islands, tbe World's first Dark Sky reserve.
Fantastic presentation by the master in this area Alyn!
Allyn is full of sh!t. With his animations..
@@ZackWolfMusic ?
I'm seeing you everywhere
@@ZackWolfMusic you never seen the galaxy then
@@yb6. U never seen the galaxy
Brilliant Ted Talk! Thank you, Alyn!
From the uploading of the video till the date it is just 57 comments mean no body really concern of this topic but many are concerned of the opposite.
I was interested on this topic as I was living in the desert region after living in a tropical country. I never see a dark sky in the desert region in addition to that street bulbs were glowing even at daytime.
I was just observing if not have time to do a statistical research to prove that trees are growing well where there is enough darkness and mostly the trees grown on road sides are not growing well. My reasoning was the light pollution and I did not have an opportunity to bring to the notice of concerned personnel to switch off the street light at least for two to four hours (12 - 4) when there will be less traffic on the road. Additionally traffic police movement can arrange to cope with emergency situations.
Really interesting, eye opening and educational. I hadn't fully appreciated the impact to the night sky from light pollution.
Excellent talk.. this is a topic that we will take in mind and seriously
Alyn Wallace, TOP BLOKE 👍🏻👍🏻👍🏻
Great talk. Love from NYC
Thank you!
Great job Alyn!!
Great job Alyn 👏🏻
I live in NY. I’ve never seen the Milky Way. I rarely see stars. All I see is a grey sky sometimes a dark orange hue.
Such a good talk.
Very good presentation 👏🏻 and really important issue.
Excellent Alyn! Very clear.
Very well said.
Top job! Keep spreading the word! We just need to get England as dark as Wales.....
Given we are are stuck with the lights we have what are the options? Filters, shields, dimming, part night lighting?
@@peterwoolliams1283 Shielding the tops and sides of light fixtures is a good start - putting some sort of cone or cylinder over them so that all of the light points towards the ground. Dimming the power helps too - reducing the wattage. Motion sensors for outdoor lights would also help, so that way the lights turn off when they're not needed.
He explained this very well.
Light pollution is a serious problem.
Brilliant, very clear evidence 👍🏻
Came from ig, I love your images!
Didn't thought I would found u here🙂
@@seekersaurabh I am everywhere where astro is :)
I’m curious who disliked the video.
electricity company's
The Japanese
Nate Johnston Jealous people
Nate Johnston ...why Japanese?
@@anitarussum4590 just look at tokyo
2:27 holyshit! It would've been nice to actually SEE THAT PICTURE!!!
Here's a link to it
Thanks for your illuminating speech kanka
Kerim Demir ....what does Kanka mean?
@@anitarussum4590 haha. Err, like Buddy, dude, pal in Turkish
This TED talk hits differently now he's no longer with us.
Who will now pick up and carry the torch as photographer and advocate for the preservation of the night skies?
The transition to LEDs was driven by a cost saving, there will be no cost saving by changing the temperature of the LED so i think sadly this will take a long time to take effect.
Alyn went to dolomites in Italy. It was breathtaking to see his photo
Good talk. Had a holiday this year in Ganllwyd (nr Dolgellau). First night was amazing, Milky Way was clearer than Kielder... but rest of week was rain! What was the Berkekley study? Any info on that much appreciated.
I was in my late 20's before I saw the milky way. Growing up in a big city I could only dream of it. Living in Dorset I can see it most times I go out in the garden, even though I'm in a suburban area. So I'm making up for lost time!
8:25 LED revolution causing various problems; blue light scatter has far more negative impacts.
I love you
Why do we need lights after 1 in the morning? Why is that normal?
The number of satellites is already ruining some of my night photos, so light pollution is not the only problem. My backyard is Bortle 4.
I agree with all of this. If one wants to accomplish the necessary change to human behavior the focus should not really be on sea turtles or bugs, or birds, but on rich folks' children. How does the light pollution negatively effect the children of people who have money? Rich people are not hippies. Rich people control the laws.
From my personal observation from a lonely island of cyclades greece That i saw every night for some years the milky way,I believe that since 1995 that they had put everywhere public light,the clobal system made that because they had problem of the working of artificial intelligence mind control programmes at the period of the nights.Because the space sattelites they didnt had total clear vision of the europe and west population generally.
I see the milky way every night when it is possible.
i can just drive for 3 minutes to see the milky way
It's really sad to see the amount of views this video has got.
Seems no one is concerned about light pollution.🙄
Let's turn off the lights in memory of Alyn.
Let’s just got back to torches man
Artificial light at night males me sick.
is it really that difficult to not cough? Really starting to wonder
It needs to be taxed. It's the only way to solve the problem.
Noise pollution, another environmental problem.
DONT GO OVERBOARD ON THE REPRODUCTION LOL
Welcome to Russia for dark skies) There are lots of Bortle 1 skies close enough to civilization, like 2-3 hours by car.
forget the lights....what about hairstyle pollution?!
