Since we moved to the country-side I can't say that I don't miss the street lights in Helsinki during the dark months, when I have to take the dog out, but then again I don't find them necessary and mostly I miss them because I am scared of going out in the complete darkness, even if I know it's silly.
The thing with light pollution is that it is not only a waste of energy but it affects our health (causes stress and disrupts our natural day-rhythm). Light pollution also affects animals and organisms.
Here are some examples on the effects on wildlife:
- Birds can become lost and confused if they can't see the stars over a bright city.
- When sea turtles hatch, the babies are supposed to follow the moon to the water. Bright beach lights, however, can lead them in the wrong direction.
- Many animals like frogs, bats and fish can experience damaging behavioral and physiological changes, such as disrupted feeding and breeding habits, as a result of light pollution.
Read more on light pollution on for example wikipedia.
Here is also a nice (but long) article in Spanish.
