Well, seeing the stars everywhere at night is the default and our activities are preventing it. So I don't think it's quite the same as seeing Niagara Falls. Light pollution is a solved problem and solving it has other potential benefits (like better sleep at night).

But no one cares. Why don't they care? I don't know. For me, the inability to see the stars at night is like not being able to see the sun during the day. It's like every night is cloudy.
