Earth Hour is an hour which we all switch off our electrical things.
It is held on 28 March 2009
It is to help the earth by using less electrical things which helps reduce global warming.
I am not very sure what people do during earth hour besides switching off lights and waiting in darkness
Earth is facing many pollutions and dangers that is treahtening it.
Besides earth hour,we can recycle,use less water and other things we can do to save earth.
