I used to do a lot of stargazing with my telescope in Brooklyn back in the 1970s. My son now does a fair amount. We already have too much light pollution.

I remember the movie Hancock, and the red heart on the moon as a way of creating empathy in people. A soda or fast food ad, jeez... I guess there will be a whole industry of garbage collection or destruction of space debris that doesn't eventually burn up in the atmosphere.
