as excessive use of artificial lighting, resulting in the disappearance of our starsnight skies.At present, more than 2016 of the international population lives under light pollution, and pollution in

activities, the animals sleeping at night suddenly extend the time of the day, because there is no longer darkness, the night animals who want to be active in the dark may try to leave their normal habitat, to escape the light, "she said."Changing the amount of light at night also means we cover up the season, which can lead to a change in reproductionxa0If the offspring are born at the wrong

a huge driving force for change.\ "It started throwing away bird migrations where birds needed Star navigation, and a German study showed that the number of Red Sea Turtles dropped sharply as they

not object to the use of artificial light, on the contrary, it urges society to use light in an appropriate and effective manner.There are very few governments and policy makers who can adapt to the problem of light pollution, so very "ordinary" urban lighting decisions are being made, he said."On a global scale, we estimate that more than outdoor lighting is actually a waste, and it is quite considerable when we use the total energy consumption for outdoor lighting, he said."As an example of a bad urban lighting, my lights have recently been upgraded.They are shooting half the light on their side so that the light does not shine on the street where people need them, but on someone's front yard.Excessive use of LED lighting makes this problem more complicated.Mr. barristers saidxa0Due to the fact that more lights are being installed now, the energy efficiency of the LED cannot be achieved.He says the blue is higher.The light in the LED has the effect of whiteningLight,

said that humans evolved from sitting by the campfire and walking in the moonlight, where their bodies were designed to be warm, low-level light at night, and weExpansion is to protect yourself from
