Light pollution is a growing environmental problem in the world, as man illuminates larger and larger parts of the globe. The illuminated area increases by more than two percent per year.
– France is one of the strictest countries. They have adopted national legislation and are very actively working on banning lights at certain times of the day. Times vary depending on the lighting function, be it a residential area or shopping centers. They also have requirements for the color temperature of the light. They try to get rid of the blue wavelengths that can affect the circadian rhythm in both humans and animals, says Annika Jägerbrand.
Outdoor artificial light, that is, different types of lamps, can have great ecological knowledge. Insects that are used to navigating in sunlight or moonlight can become disoriented and have a difficult time surviving. A strong light can mean that they are not finding food or are not finding a mate. But even many mammals, such as bats, can become so disturbed that they cannot cope and live in buildings with facade lighting.
But it’s not just France which works to reduce light pollution problems, this also applies, for example, to Italy and Germany, where, among other things, insect habitats are protected. Annika Jägerbrand says that Sweden is lagging behind and that this is partly due to a lack of commitment from the environmental movement.
– We do not have an active environmental movement in this area.
