Solutions include using lower intensity lights, turning lights off when people leave an area, and choosing LED lights that are amber instead of blue or violet, since these tend to be the most harmful to animals and humans, experts say.”We’ll Explosion-proof Electrical Factory light something that we didn’t light before, like a bicycle path though a park or a section of highway leading outside of town that in the past wasn’t lit,” he said.”Excess nighttime light not only harms natural habitats and makes stargazing impossible, it also costs nearly seven billion dollars annually in “negative impacts on wildlife, health, astronomy, and wasted energy,” according to a 2010 study in the journal Ecological Economics.But even though Milan, for example, made the switch to LED lights and saw a drop in radiance over the 2012-2016 period, there were increases elsewhere in Italy.
They were supposed to bring about an energy revolution — but the popularity of LED lights is driving an increase in light pollution worldwide, with dire consequences for human and animal health, researchers said Wednesday.Researchers only analyzed nighttime lights during the months of October, to avoid any increase from holiday lights.”There is no conclusive evidence that additional light reduces crime,” Longcore said.2 percent per year from 2012 to 2016.”With few exceptions, growth in lighting occurred throughout South America, Africa, and Asia,” said the report.People also need to question their assumptions, for instance, that nighttime lights make the world safer.2 percent per year from 2012 to 2016.
The VIIRS is mounted on the a National Oceanic and Atmospheric Administration (NOAA) satellite named Suomi NPP, which has been orbiting Earth since October 2011.”We can say with fairly high confidence even though we didn’t measure in the satellite an increase in these countries, they are nearly certainly increasing in brightness in terms of how human beings would perceive the light,” Kyba said.
