We could get rid of a lot of it, and save money, by getting the authorities to buy the right kind of street lighting. Most street lighting lets far too much light go above the horizon.

Even cheaper, tun them off after the pub closes.
In the village down the road from my unlit garden, lights go out at 22:00. Next house to me, straight line distance, 4km. Good for starwatching. On a good night I can see all of the pleiades naked eye (plus glasses, duh)
But it's still a long way to the chemist.
