I'm all in favour of luminescent mood lightening. Worked on Pandora.
But there is a practical problem with trees: they are so slow to
install. Outside my window I have a smallish tree that is ~30 years old.
Along my street many of the big trees are at least 60 years old or more.
So replacing the street-lights would take many decades. Maybe we should
go for bioluminescent ivy or wines.
Crime prevention: light doesn't really deter crimes, human visibility
does. Being alone on a well-lit street with empty offices is no real
comfort. But people tend to feel better about well-lit areas, so from a
comfort standpoint it matters. This is also why person-sensitive lamps
don't really help: you do not see where you are going, and this is
It is worth remembering that many people need light when walking at
night (or morning/afternoon in the case of Sweden). I am sure that to an
American it sounds downright strange that a sizeable fraction of people
here get to their jobs/homes by walking, including many with rather bad
eyesight. Or, as the case might be, drunk.
