Light pollution

Light pollution is a type of pollution. It is defined as “any adverse (or bad) effect as a result of man-made lights.” Usually, this means too much light. Several species, including plants and humans, are badly affected by light pollution. Most people have never heard of light pollution, and those who have usually don’t care, or do anything about it. Light pollution costs Americans billions of dollars every year.

There are five kinds of light pollution:

• Sky glow
• Light trespass
• Over-illumination
• Clutter
• Glare

Sky glow usually has more of an effect on the environment than light trespass and glare, but all of them are a major problem to people today.

Sky glow is the kind of light pollution that prevents people from seeing the moon and the stars. This causes birds to not be able to migrate to the right place because they can not follow the moon and stars. Sky glow also prevents astronomers from making discoveries.

Light trespass is when light being used by a person goes into the property of another. Though light trespass is not an environmental issue, it is still light pollution.

The third kind of light pollution, glare, has different kinds. The first, disability glare, is the loss of visibility because of too many lights. Discomfort glare is when the lights cause pain..
