Light Pollution is killing the stars.
A little melodramatic I know but so many urban dwellers have never seen the milkyway, something which up until the last 200 years or so(probably even less than that) was a common sight in our night skies.
There is an independent film coming out this summer called The City Dark
It looks at the problem of light pollution and the potential long term ramification it has on humans as well as other animals as we move towards a 24/7 global society.
The trailer seems interesting and I am looking forward to watching it.
