On Saturday, March 27th, at 8:30 local time, the lights will go out in millions of homes, businesses, and schools in celebration of Earth Hour 2010. Started in Sydney, Australia in 2007, Earth Hour is now a global event organized by WWF in which people show their support for environmental action by turning off the lights for one hour. This year, 120 countries and territories will take part in this show of solidarity (up from 88 last year).
