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 KZfaq channel and hosting astophotography workshops in Wales and Europe. His work can be found at: alynwallacephotography.com/.
