We recognize the need and often the requirement for safety and security reasons. In an attempt to shed light on the effects of non-natural light in the environment during normal periods of darkness, multiple factors must be considered and evaluated.
How can Light Pollution be defined so we understand what it is?
Most people think that, as we sleep at night, the rest of the species do the same, with a few exceptions, so it is of no concern if we send out a little light into the night time environment … … the biological activity of our fauna is more intense at night than during the day and this fauna needs the night for their normal activities.
Therefore, we do not realize that protecting the night sky is a valuable step to conserving bio-diversity. We rarely stop to think that the night is necessary and good for life.
