artists depiction of epsilon aurigae from free program

Hidden Costs of Light Pollution. Video transcript: It's more than one billion cars burning 2 billion headlights It's argon gas and less than an inch of tungsten metal swinging naked from the ceiling.

It's malls. It's your work. It's outside your bedroom window keeping you from sleeping. It's insomnia. It's the slow extinction of animals and insects dependent on darkness for migration and mating. It's the device you obsessively check as you walk down the street raising your dopamine levels while reducing your melatonin. It's a carcinogen. It's one of the reasons women in developed nations are five times more likely to have breast cancer. It's looking down instead of up.
