One thing that I wish the article would've covered is how light pollution affects sleeping patterns for humans. Light pollution is one of the big problems with cities considering how lights both installed by the government and private individuals are poorly setup and waste most of their lighting potential on illuminating the sky or things further away than intended. If governments were more serious about this, then we could have well lit cities that don't constantly blast all their light into the sky or into bedroom windows all the time. Just a tweak in design or placement is often all it takes to minimize light pollution.
