Light Pollution 

When there's so very many lights from a city that it obscures the night sky, making star~viewing almost non~existant.

Gawd, I Hate Light Pollution because it interferes so badly with my viewing of the stars & moon at night! There's so much better viewing in a small city or the countryside!

light pollution is the misuse of artificial lighting at night, where so many lamps spill light upwards so that the dark sky is no longer dark. The stars are not visible, and this causes so many horrible things, silently killing off our planet.

Johnny: "Hey, where'd the stars go?!"

Annie: "There are so many lights that shine into the sky, the beautiful night sky is hidden from our view. To reverse light pollution, people can change all lights to ones that shine their light downwards, where it is needed."
