Will there eventually be more light pollution? Does it matter if we turn on one more lamp when there is already a lot of light in the area?
Yes, the amount of light pollution increases by around 8% annually in Denmark. Worldwide, light pollution increases by around 10%.
The increasing light pollution means that we will soon not be able to see a dark sky anywhere.
Light pollution spreads without boundaries, so places that try to limit light pollution will end up having their night skies destroyed by light pollution from other areas.
Every lamp counts
The total amount of light that spreads into the sky increases every time a new lamp is switched on.
You often hear the excuse that there are so many other lamps, so it makes no difference if there is one more or less.
But that is wrong. Every new lamp increases light pollution, and every lamp that is switched off will reduce light pollution to the surroundings.
