Некоторые ученые придерживаются сенсационной точки зрения, что в течение двух лет европейская цивилизация исчезнет... Кому выгодна гибель Европы и как это скажется на России?

Scientists observed light pollution by mounting a radiometer designed especially for nighttime lights to a NOAA satellite that orbited the Earth for four years. They found that the fastest increase in the amount of artificial light is coming from developing countries, and the growth in light pollution corresponds to the global growth of gross domestic product.
In addition to the light that has been measured, more light pollution is going undetected because the sensor used in the study cannot measure light below 500 nanometers, including some of the blue light that LED bulbs emit.
Light pollution, particularly the blue light emitted by LED bulbs, doesn’t just make it hard to stargaze. It can cause serious consequences for wildlife, whose biological rhythms and nocturnal instincts are disrupted when they are near a lot of artificial light. In humans, it can disrupt circadian rhythms and make it harder to see when driving at night. And in some cases, it can even make spring arrive early.
The researchers involved in the study say there is hope that the negative impacts of light pollution can be mitigated. Well-designed LED lamps can cut down on the amount of wasted light that the bulbs emit without creating a noticeable difference for human users. Kyba, who led the study, also says that saving energy while reducing light pollution is certainly possible, as long as the energy that is saved isn’t spent on adding more light sources.
