This excess of consumption that must supply the power stations, is more fuel consumption and, consequently, higher emissions of polluting gases into the atmosphere, among other things responsible for the greenhouse effect is increasing the average temperature of our planet and acid rain that destroys forests.
Glare:
Light falling directly from the lamp in our eyes has an intensity well above that comes reflected from the ground and the obstacles it presented, we see them doing worse since the opening of the pupils has closed to adjust to that light intensity.

By illuminating facades and windows with no light addressed to soil produce enough discomfort and facilitates the indiscretion of the passers-by.
Becomes difficult and obscure vision of the starry sky: This is a really unfortunate consequence for all and especially for the astronomer, as this wonderful spectacle, an inexhaustible source of knowledge and beauty, which undoubtedly is the vision of the rest of the Universe which we belong, has degraded so because of such contamination, until we have lost the habit of looking at the sky at night, after no longer get our attention.
