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.

[@illsdom6055]

watching this after Alyn passing away it's truly sad. We've lost an master this field but more important, we've lost a man with big heart. Thanks for all

[@account4935]

Rest in peace alyn😢

[@FilippoMasoni]

Such an important topic that we should take a lot more seriously. Thank you Alyn for the great talk!

[@Barkley4680y]

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.

[@jefffiles9209]

Great talk from a master in his field. This should make us all sit up a think!!

Amazing job. Time to shed some more light ironically, to this subject.

[@joshuarhys1644]

Great talk Alyn! I was born in Wales, but never realised how beautiful the night sky could be until I visited Switzerland.

[@alisonfairley5444]

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.

[@BotSquadTalks]

Great job.... I'm very lucky where I live.... North Norfolk. Great presentation.

[@ayeshamartin_868]

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?

[@deepquake9]

Beautiful. I live in guatemala and we have many areas that are amazing to view the milkyway!

[@EnigMagnum]

i follow his youtube channel..such a nice guy... love his content on astro photography

[@gauravlokhande99]

Light pollution is also major issue. We must have to Raise voice against it & try to fix this issue...

[@natejohnston480]

It disgusts me when i see big cities, love it when you are out in total darkness and just the stars

[@madhavsharma6643]

i am an astrophotographer too ... hate light pollution but this was too big and deep dive into disadvantages of light pollution love alyn

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.

[@MatthewVandeputte]

Such a good talk.

[@jbairdexp]

Really interesting, eye opening and educational. I hadn't fully appreciated the impact to the night sky from light pollution.

[@marlonlom]

Excellent talk.. this is a topic that we will take in mind and seriously

[@cynthiahh5209]

Very informative presentation. Helped me a lot with my research paper. Grateful!

Brilliant Ted Talk! Thank you, Alyn!

[@johnadastra1754]

Saddened to hear of the passing of Alyn. Taken from us way too soon!

[@peterwoolliams1283]

Top job! Keep spreading the word! We just need to get England as dark as Wales.....

[@peterwoolliams1283]

Given we are are stuck with the lights we have what are the options? Filters, shields, dimming, part night lighting?

[@ayjanu]

@@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.

[@firdhousr]

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.

[@dominiclester3232]

Excellent Alyn! Very clear.

[@krissifadwa]

He explained this very well.

[@joec.9591]

Light - and noise - pollution are extremely destructive, more so than anything else, in my experience.

Great talk. Love from NYC

[@CookedLight]

Brilliant, very clear evidence 👍🏻

[@Bee0213]

Great job Alyn 👏🏻

[@w-james9277]

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!

[@a1dreamer]

Very good presentation 👏🏻 and really important issue.

[@TheRealSmiTTTen]

Thank you!

[@ashbydav]

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.

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.

[@raghavchaudhary5748]

The irony is that the blue LED is a Nobel Prize winning invention.

[@peterjones6507]

Yes. Another award given by mad scientists to mad scientists. I expect a nomination soon for the inventors of Covid19.

[@cteyemrdy6927]

Light pollution is a serious problem.

[@peter7624]

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!

I am glad more people are becoming aware of the light pollution issue. It isn't just a local one. This problem has become global and is likely affecting migration patterns and God knows what else. If the night sky cannot be our guiding light, what can we rely on?

[@davidhuth5659]

Let's turn off the lights in memory of Alyn.

[@DougGrinbergs]

8:25 LED revolution causing various problems; blue light scatter has far more negative impacts.

[@BluegrassBuzzbomb]

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.

[@TheNadders]

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.

[@MayorInCheif]

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.

[@danwray5626]

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.

Noise pollution, another environmental problem.

It needs to be taxed. It's the only way to solve the problem.

I see the milky way every night when it is possible.

[@dimitrismitsopoulos4265]

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.
