Disgusting.
Dont spread this kind of propaganda pls.
What is the use of such a gimmick?
I am a bit disgusted by some rich people from some rich
countries who are always thinking for themselves and come up with
feel-good gimmicks while putting on pretentious themes like "earth
hour".
A poor kid in Africa does not need to be told that his family
should turn off electricity for one hour, maybe they dont have any
electricity at all, or maybe they need it because they need the
lamp to read and finish his homework.
Disgusting.
I agree with Meat Pao, people living in third-world countries or
environment/situations suffers and are still suffering Earth Hour
every hours in their lives.
I'm also celebrating no 50k ring Day everyday. 
I remembered there used to be a No-Underwear Day where people
are not allowed to wear any underwear at all underneath their
clothes.
Don't remember where I bumped across this weird festival
already....does anyone know?
