• There are many sources of light. The most common light sources are thermal: a body at a given temperature emits a characteristic of black body radiation.

• “Many of the effects of natural light may put whole ecosystems in danger.”
• By changing the environment on which animals develop and reproduce, natural light effects their lives and the growing of their species.”

• Categories of light pollution include light trespass, over-illumination, glare, clutter, and sky glow.
• Light trespass occurs when unwanted light enters one's property by shining over a neighbor’s fence.
• Over-illumination is the excessive use of light.
• Glare is the result of contrast between bright and dark areas in the field of view.
• Clutter refers to continues groupings of lights.
• Sky glow refers to the "glow" effect that can be seen over populated areas.
