Let's see... I love to gaze into a clear sky on a dark night out in the country as much as the next guy -- really, I do! -- but, if the choice is between light pollution and living in 1948, I'll take the light pollution, thank you very much. ;-)
"99%"? Two-thirds of the planet is covered with water. Of the remaining one third, maybe 15% (at worst?) is "polluted" with light.
You could always go out to sea, move out to the country, or settle in N. Korea, China, Greenland, ... if that's your idea of living.
It isn't necessary to choose lights or darkness. We can have both. In fact, this is the law in several communities, in a couple of states, and in a few countries already. Simply control the lighting so it doesn't glare into your neighbor's yard, and stop letting all those light rays escape into the sky; shield those fixtures so the light goes where it is needed.
