Science in Seconds - Light Pollution

Science in Seconds Know Everything RANTS – Light Pollution Torah Kachur: Our cities, and our planet is now the victim of light pollution. Our determination to light up our lives has wrecked havoc with creepy crawlies, birds, and our own bodies. Why, that sounds terribly dangerous, and it is. It's time to embrace the darkness. Like a moth to a flame, many insects are attracted to the artificial light, in the middle of night, that just shouldn't be there, which means they're sitting ducks for predators. Population levels are changing because we're too lazy to turn off our porch light. This may have serious implications to population levels of insects and their predators, all the way up the food chain. It's not just gross insects. It's also baby sea turtles. The hatchlings normally scramble to the reflection of the ocean to start their lives. But now they're more attracted to the lights of the big city. This is not a quest for Broadway, but a march to their deaths. The 9/11 Tribute in Light, on the 10th anniversary, was poignant for more than just a memorial to those lost. It was also evidence of how our towering lit skyscrapers disrupt bird migration. The longer artificial days we have created have been shown to cause early breeding in birds and early migrations, resulting in population declines from reduced breeding success. Not to mention what light pollution is doing to our own bodies. The presence of light defines our circadian rhythm, the unconscious sleep‑wake cycle that impacts our health. Several studies have linked increased breast cancer risk to women exposed to unnatural levels of light at night, possibly through suppressing a hormone called melatonin. Reduced melatonin levels have also been linked to immune suppression, type 2 diabetes, coronary heart disease, and even obesity. It's time to not see. The dark is the new green, so dim it or hit the switch. Courtesy of Science in Seconds – All rights reserved No profit or advertisement use allowed. (Translators are invited to put their name here)

Digital advertising, sky scrapers with lights on all night long and garden lights are more than just a drain on our electrical grid, they are seriously affecting the tiny little critters that need the night. No, not vampires but beetles, possums, turtles, birds, spiders and moths.

Make darkness your new best friend.
