Earth Hour, the largest environmental event in history, is an activity families can easily do together to raise awareness about protecting the planet. Every year, hundreds of millions of people, businesses, and governments worldwide switch off their lights for an hour to send an impactful message and call to action regarding climate change.
During last year’s Earth Hour 2011, more than 5,200 cities and towns in 135 countries worldwide participated in this global event. Earth Hour is scheduled on the last Saturday of every March to closely coincide with the equinox so that most cities around the world will be in the dark.
