Light Pollution And ‘The End Of Night’ (Tom Ashbrook, On Point)

Evening falls, and then night, and we look up into that nighttime sky, in all its glory, and see… well, there was a time when we all saw a slew of stars and planets and galaxies.
These days, many, most, are likely to look up and see reflected man-made light from street lights and gas stations, shopping centers and parking lots.  Blazing away.  Banishing the dark.
We’ve lost the dark – the true dark – says my guest today, Paul Bogard.  And with it, true night.  And, he says, there are consequences.
This hour, On Point:  our vanishing darkness and the end of night./Tom Ashbrook
