Topic of Conversation: Light Pollution, or “Bring back the stars!”
For this discussion, you’ll need to first watch the documentary “The City Dark” at the following link:
Then make a Star Wheel (also called planisphere) using this link: https://in-the-sky.org/planisphere/index.php (Links to an external site.)
Go outside with your Star Wheel one evening (when it is not cloudy) and make note of how many stars you SHOULD be able to see and how many you ACTUALLY see. (If you have time, go to a rural area (if you live in the city) or a city area (if you live in a rural area) and repeat for comparison.)
In your initial two paragraph post, comment on the following questions:
Approximately what percentage of the stars you SHOULD be able to see (as indicated by your Star Wheel) COULD you actually see? If you did the comparison in a different location (rural vs. city), what did you observe there? Have you ever experienced the night sky without light pollution? If so, tell us about that experience.
The documentary brings up interesting studies about light and biological implications for sea turtles, birds, fireflies, and humans. What are your thoughts about “disruption of habitat”?
The city of Bar Harbor is featured for their ordinance against light pollution. Do you feel legislation is necessary? What responsibility do lawmakers have and what responsibility do individuals have? How does safety play a part in these decisions?
I live in Indianapolis, IN.
