The main reason it's mostly astronomers who care and they're being ignored is that it's not even close to "havoc".

I grew up near Portsmouth in the UK. Most nights, the stars were hidden by the kind of orange glow that a political cartoonist would use for Donald Trump's face, thanks to all the sodium vapour street lamps.

Things are so much better than they used to be (also I've moved) but that childhood memory? Most don't even think of that as "havoc".
