Light pollution is excess or obtrusive lights created by humans. Among other
effects, it causes adverse health effects, obscures most stars to city dwellers,
interferes with astronomical observations, wastes energy and desrupts
ecosystems.

We can do little about it as the whole world is trying to turn the attention of
all the people to the said matter. Have you heard of the recent news that the
lights of Hong Kong city will be turned off for one hour just to remind people that light pollution can be avoided if we are a little frugal with the use of
electricity?
Just type "Light pollution" onto the search windows of your
computer, and you can read numerous articles on the same subject in details.
