Earth Hour

I think earth hour is an hour when everyone offs their lights at home.I just know that Earth hour falls on a Saturday.I think people are organising this event to save the earth.They will be offing all their lights at home and taking lit candles around their house.We could do nothing as all the things that we want to do use electricity.the other problems Earth is facing is water pollution and air pollution.We should not throw anything into the water.
