Light pollution

Light pollution is another kind of environment pollution.

Light Pollution

Light pollution is the brightening of the night sky inhibiting the visibility of stars and planets by the use of improper lighting of communities. Some examples of what causes light pollution:

• Street lamps that shine light in all directions, instead of with a hood to point light downward toward the street.
• Extra, unnecessary lights around the home
• Cities that run lights all night long

Light pollution uses more energy (by shining more light up instead of down, meaning you need brighter bulbs for the same amount of light), may affect human health and our sleep cycles, and most importantly, corrupts our kids telescopes and their curiosity. (I grew up in a city. My first no-light night in the country blew my mind. Let's not make that such a rare occasion!)
